To compile and install SDL:
0. If you have downloaded this from the website, skip to the next step.
If you have checked this out from subversion, you'll need to run
./autogen.sh to build the configure script.
1. Run './configure; make; make install'
If you are compiling for Windows using gcc, read the FAQ at:
http://www.libsdl.org/faq.php?action=listentries&category=4#42
If you are compiling using Visual C++ on Win32, you should read
the file VisualC.html
2. Look at the example programs in ./test, and check out the HTML
documentation in ./docs to see how to use the SDL library.
3. Join the SDL developer mailing list by sending E-mail to
sdl-request@libsdl.org
and put "subscribe" in the subject of the message.
Or alternatively you can use the web interface:
http://www.libsdl.org/mailing-list.php
That's it!

To compile and install SDL:
1. Windows with Visual Studio:
* Read VisualC.html
Windows with gcc, either native or cross-compiling:
* Read the FAQ at http://wiki.libsdl.org/moin.fcg/FAQWindows
* Run './configure; make; make install'
Mac OS X with Xcode:
* Read README-macosx.txt
Mac OS X from the command line:
* Run './configure; make; make install'
Linux and other UNIX systems:
* Run './configure; make; make install'
Android:
* Read README-android.txt
iOS:
* Read README-ios.txt
Using Cmake:
* Read README-cmake.txt
2. Look at the example programs in ./test, and check out the online
documentation at http://wiki.libsdl.org/
3. Join the SDL developer mailing list by sending E-mail to
sdl-request@libsdl.org
and put "subscribe" in the subject of the message.
Or alternatively you can use the web interface:
http://www.libsdl.org/mailing-list.php
That's it!

Simple DirectMedia Layer
(SDL)
Version 2.0
---
http://www.libsdl.org/
This is the Simple DirectMedia Layer, a general API that provides low
level access to audio, keyboard, mouse, joystick, 3D hardware via OpenGL,
and 2D framebuffer across multiple platforms.
The current version supports Windows, Windows CE, Mac OS X, Linux, FreeBSD,
NetBSD, OpenBSD, BSD/OS, Solaris, iOS, and Android. The code contains
support for other operating systems but those are not officially supported.
SDL is written in C, but works with C++ natively, and has bindings to
several other languages, including Ada, C#, Eiffel, Erlang, Euphoria,
Go, Guile, Haskell, Java, Lisp, Lua, ML, Objective C, Pascal, Perl, PHP,
Pike, Pliant, Python, Ruby, and Smalltalk.
This library is distributed under the zlib license, which can be found
in the file "COPYING".
The best way to learn how to use SDL is to check out the header files in
the "include" subdirectory and the programs in the "test" subdirectory.
The header files and test programs are well commented and always up to date.
More documentation is available in HTML format in "docs/index.html", and
a documentation wiki is available online at:
http://www.libsdl.org/cgi/docwiki.cgi
The test programs in the "test" subdirectory are in the public domain.
Frequently asked questions are answered online:
http://www.libsdl.org/faq.php
If you need help with the library, or just want to discuss SDL related
issues, you can join the developers mailing list:
http://www.libsdl.org/mailing-list.php
Enjoy!
Sam Lantinga (slouken@libsdl.org)

Simple DirectMedia Layer for Android
================================================================================
Requirements:
Android SDK (version 10 or later)
http://developer.android.com/sdk/index.html
Android NDK r7 or later
http://developer.android.com/sdk/ndk/index.html
Minimum API level supported by SDL: 10 (Android 2.3.3)
================================================================================
How the port works
================================================================================
- Android applications are Java-based, optionally with parts written in C
- As SDL apps are C-based, we use a small Java shim that uses JNI to talk to
the SDL library
- This means that your application C code must be placed inside an Android
Java project, along with some C support code that communicates with Java
- This eventually produces a standard Android .apk package
The Android Java code implements an "Activity" and can be found in:
android-project/src/org/libsdl/app/SDLActivity.java
The Java code loads your game code, the SDL shared library, and
dispatches to native functions implemented in the SDL library:
src/SDL_android.c
Your project must include some glue code that starts your main() routine:
src/main/android/SDL_android_main.c
================================================================================
Building an app
================================================================================
Instructions:
1. Copy the android-project directory wherever you want to keep your projects
and rename it to the name of your project.
2. Move or symlink this SDL directory into the <project>/jni directory
3. Edit <project>/jni/src/Android.mk to include your source files
4. Run 'ndk-build' (a script provided by the NDK). This compiles the C source
If you want to use the Eclipse IDE, skip to the Eclipse section below.
5. Create <project>/local.properties and use that to point to the Android SDK directory, by writing a line with the following form:
sdk.dir=PATH_TO_ANDROID_SDK
6. Run 'ant debug' in android/project. This compiles the .java and eventually
creates a .apk with the native code embedded
7. 'ant debug install' will push the apk to the device or emulator (if connected)
Here's an explanation of the files in the Android project, so you can customize them:
android-project/
AndroidManifest.xml - package manifest. Among others, it contains the class name
of the main Activity and the package name of the application.
build.properties - empty
build.xml - build description file, used by ant. The actual application name
is specified here.
default.properties - holds the target ABI for the application, android-10 and up
project.properties - holds the target ABI for the application, android-10 and up
local.properties - holds the SDK path, you should change this to the path to your SDK
jni/ - directory holding native code
jni/Android.mk - Android makefile that can call recursively the Android.mk files
in all subdirectories
jni/SDL/ - (symlink to) directory holding the SDL library files
jni/SDL/Android.mk - Android makefile for creating the SDL shared library
jni/src/ - directory holding your C/C++ source
jni/src/Android.mk - Android makefile that you should customize to include your
source code and any library references
res/ - directory holding resources for your application
res/drawable-* - directories holding icons for different phone hardware. Could be
one dir called "drawable".
res/layout/main.xml - Usually contains a file main.xml, which declares the screen layout.
We don't need it because we use the SDL video output.
res/values/strings.xml - strings used in your application, including the application name
shown on the phone.
src/org/libsdl/app/SDLActivity.java - the Java class handling the initialization and binding
to SDL. Be very careful changing this, as the SDL library relies
on this implementation.
================================================================================
Customizing your application name
================================================================================
To customize your application name, edit AndroidManifest.xml and replace
"org.libsdl.app" with an identifier for your product package.
Then create a Java class extending SDLActivity and place it in a directory
under src matching your package, e.g.
src/com/gamemaker/game/MyGame.java
Here's an example of a minimal class file:
--- MyGame.java --------------------------
package com.gamemaker.game;
import org.libsdl.app.SDLActivity;
/*
* A sample wrapper class that just calls SDLActivity
*/
public class MyGame extends SDLActivity { }
------------------------------------------
Then replace "SDLActivity" in AndroidManifest.xml with the name of your
class, .e.g. "MyGame"
================================================================================
Customizing your application icon
================================================================================
Conceptually changing your icon is just replacing the "ic_launcher.png" files in
the drawable directories under the res directory. There are four directories for
different screen sizes. These can be replaced with one dir called "drawable",
containing an icon file "ic_launcher.png" with dimensions 48x48 or 72x72.
You may need to change the name of your icon in AndroidManifest.xml to match
this icon filename.
================================================================================
Loading assets
================================================================================
Any files you put in the "assets" directory of your android-project directory
will get bundled into the application package and you can load them using the
standard functions in SDL_rwops.h.
There are also a few Android specific functions that allow you to get other
useful paths for saving and loading data:
SDL_AndroidGetInternalStoragePath()
SDL_AndroidGetExternalStorageState()
SDL_AndroidGetExternalStoragePath()
See SDL_system.h for more details on these functions.
The asset packaging system will, by default, compress certain file extensions.
SDL includes two asset file access mechanisms, the preferred one is the so
called "File Descriptor" method, which is faster and doesn't involve the Dalvik
GC, but given this method does not work on compressed assets, there is also the
"Input Stream" method, which is automatically used as a fall back by SDL. You
may want to keep this fact in mind when building your APK, specially when large
files are involved.
For more information on which extensions get compressed by default and how to
disable this behaviour, see for example:
http://ponystyle.com/blog/2010/03/26/dealing-with-asset-compression-in-android-apps/
================================================================================
Pause / Resume behaviour
================================================================================
If SDL is compiled with SDL_ANDROID_BLOCK_ON_PAUSE defined (the default),
the event loop will block itself when the app is paused (ie, when the user
returns to the main Android dashboard). Blocking is better in terms of battery
use, and it allows your app to spring back to life instantaneously after resume
(versus polling for a resume message).
Upon resume, SDL will attempt to restore the GL context automatically.
In modern devices (Android 3.0 and up) this will most likely succeed and your
app can continue to operate as it was.
However, there's a chance (on older hardware, or on systems under heavy load),
where the GL context can not be restored. In that case you have to listen for
a specific message, (which is not yet implemented!) and restore your textures
manually or quit the app (which is actually the kind of behaviour you'll see
under iOS, if the OS can not restore your GL context it will just kill your app)
================================================================================
Threads and the Java VM
================================================================================
For a quick tour on how Linux native threads interoperate with the Java VM, take
a look here: http://developer.android.com/guide/practices/jni.html
If you want to use threads in your SDL app, it's strongly recommended that you
do so by creating them using SDL functions. This way, the required attach/detach
handling is managed by SDL automagically. If you have threads created by other
means and they make calls to SDL functions, make sure that you call
Android_JNI_SetupThread before doing anything else otherwise SDL will attach
your thread automatically anyway (when you make an SDL call), but it'll never
detach it.
================================================================================
Using STL
================================================================================
You can use STL in your project by creating an Application.mk file in the jni
folder and adding the following line:
APP_STL := stlport_static
For more information check out CPLUSPLUS-SUPPORT.html in the NDK documentation.
================================================================================
Additional documentation
================================================================================
The documentation in the NDK docs directory is very helpful in understanding the
build process and how to work with native code on the Android platform.
The best place to start is with docs/OVERVIEW.TXT
================================================================================
Using Eclipse
================================================================================
First make sure that you've installed Eclipse and the Android extensions as described here:
http://developer.android.com/sdk/eclipse-adt.html
Once you've copied the SDL android project and customized it, you can create an Eclipse project from it:
* File -> New -> Other
* Select the Android -> Android Project wizard and click Next
* Enter the name you'd like your project to have
* Select "Create project from existing source" and browse for your project directory
* Make sure the Build Target is set to Android 2.0
* Click Finish
================================================================================
Using the emulator
================================================================================
There are some good tips and tricks for getting the most out of the
emulator here: http://developer.android.com/tools/devices/emulator.html
Especially useful is the info on setting up OpenGL ES 2.0 emulation.
Notice that this software emulator is incredibly slow and needs a lot of disk space.
Using a real device works better.
================================================================================
Troubleshooting
================================================================================
You can create and run an emulator from the Eclipse IDE:
* Window -> Android SDK and AVD Manager
You can see if adb can see any devices with the following command:
adb devices
You can see the output of log messages on the default device with:
adb logcat
You can push files to the device with:
adb push local_file remote_path_and_file
You can push files to the SD Card at /sdcard, for example:
adb push moose.dat /sdcard/moose.dat
You can see the files on the SD card with a shell command:
adb shell ls /sdcard/
You can start a command shell on the default device with:
adb shell
You can remove the library files of your project (and not the SDL lib files) with:
ndk-build clean
You can do a build with the following command:
ndk-build
You can see the complete command line that ndk-build is using by passing V=1 on the command line:
ndk-build V=1
If your application crashes in native code, you can use addr2line to convert the
addresses in the stack trace to lines in your code.
For example, if your crash looks like this:
I/DEBUG ( 31): signal 11 (SIGSEGV), code 2 (SEGV_ACCERR), fault addr 400085d0
I/DEBUG ( 31): r0 00000000 r1 00001000 r2 00000003 r3 400085d4
I/DEBUG ( 31): r4 400085d0 r5 40008000 r6 afd41504 r7 436c6a7c
I/DEBUG ( 31): r8 436c6b30 r9 435c6fb0 10 435c6f9c fp 4168d82c
I/DEBUG ( 31): ip 8346aff0 sp 436c6a60 lr afd1c8ff pc afd1c902 cpsr 60000030
I/DEBUG ( 31): #00 pc 0001c902 /system/lib/libc.so
I/DEBUG ( 31): #01 pc 0001ccf6 /system/lib/libc.so
I/DEBUG ( 31): #02 pc 000014bc /data/data/org.libsdl.app/lib/libmain.so
I/DEBUG ( 31): #03 pc 00001506 /data/data/org.libsdl.app/lib/libmain.so
You can see that there's a crash in the C library being called from the main code.
I run addr2line with the debug version of my code:
arm-eabi-addr2line -C -f -e obj/local/armeabi/libmain.so
and then paste in the number after "pc" in the call stack, from the line that I care about:
000014bc
I get output from addr2line showing that it's in the quit function, in testspriteminimal.c, on line 23.
You can add logging to your code to help show what's happening:
#include <android/log.h>
__android_log_print(ANDROID_LOG_INFO, "foo", "Something happened! x = %d", x);
If you need to build without optimization turned on, you can create a file called
"Application.mk" in the jni directory, with the following line in it:
APP_OPTIM := debug
================================================================================
Memory debugging
================================================================================
The best (and slowest) way to debug memory issues on Android is valgrind.
Valgrind has support for Android out of the box, just grab code using:
svn co svn://svn.valgrind.org/valgrind/trunk valgrind
... and follow the instructions in the file README.android to build it.
One thing I needed to do on Mac OS X was change the path to the toolchain,
and add ranlib to the environment variables:
export RANLIB=$NDKROOT/toolchains/arm-linux-androideabi-4.4.3/prebuilt/darwin-x86/bin/arm-linux-androideabi-ranlib
Once valgrind is built, you can create a wrapper script to launch your
application with it, changing org.libsdl.app to your package identifier:
--- start_valgrind_app -------------------
#!/system/bin/sh
export TMPDIR=/data/data/org.libsdl.app
exec /data/local/Inst/bin/valgrind --log-file=/sdcard/valgrind.log --error-limit=no $*
------------------------------------------
Then push it to the device:
adb push start_valgrind_app /data/local
and make it executable:
adb shell chmod 755 /data/local/start_valgrind_app
and tell Android to use the script to launch your application:
adb shell setprop wrap.org.libsdl.app "logwrapper /data/local/start_valgrind_app"
If the setprop command says "could not set property", it's likely that
your package name is too long and you should make it shorter by changing
AndroidManifest.xml and the path to your class file in android-project/src
You can then launch your application normally and waaaaaaaiiittt for it.
You can monitor the startup process with the logcat command above, and
when it's done (or even while it's running) you can grab the valgrind
output file:
adb pull /sdcard/valgrind.log
When you're done instrumenting with valgrind, you can disable the wrapper:
adb shell setprop wrap.org.libsdl.app ""
================================================================================
Why is API level 10 the minimum required?
================================================================================
API level 10 is required because SDL requires some functionality for running not
available on older devices and some for building which is not in older NDK/SDKs.
Support for native OpenGL ES and ES2 applications was introduced in the NDK for
API level 4 and 8. EGL was made a stable API in the NDK for API level 9, which
has since then been obsoleted, with the recommendation to developers to bump the
required API level to 10.
As of this writing, according to http://developer.android.com/about/dashboards/index.html
about 90% of the Android devices accessing Google Play support API level 10 or
higher (March 2013).
================================================================================
A note regarding the use of the "dirty rectangles" rendering technique
================================================================================
If your app uses a variation of the "dirty rectangles" rendering technique,
where you only update a portion of the screen on each frame, you may notice a
variety of visual glitches on Android, that are not present on other platforms.
This is caused by SDL's use of EGL as the support system to handle OpenGL ES/ES2
contexts, in particular the use of the eglSwapBuffers function. As stated in the
documentation for the function "The contents of ancillary buffers are always
undefined after calling eglSwapBuffers".
Setting the EGL_SWAP_BEHAVIOR attribute of the surface to EGL_BUFFER_PRESERVED
is not possible for SDL as it requires EGL 1.4, available only on the API level
17+, so the only workaround available on this platform is to redraw the entire
screen each frame.

CMake build system for SDL (www.cmake.org)
================================================================================
SDL's build system was traditionally based on autotools. Over time, this
approach has suffered from several issues across the different supported
platforms.
To solve these problems, a new build system based on CMake is under development.
It works in parallel to the legacy system, so users can experiment with it
without complication.
While still experimental, the build system should be usable on the following
platforms:
* FreeBSD
* Linux
* VS.NET 2010
* MinGW and Msys
* OS X with support for XCode
================================================================================
Usage
================================================================================
Assuming the source for SDL is located at ~/sdl
cd ~
mkdir build
cd build
cmake ../sdl
This will build the static and dynamic versions of SDL in the ~/build directory.

SDL on DirectFB
Supports:
- Hardware YUV overlays
- OpenGL - software only
- 2D/3D accelerations (depends on directfb driver)
- multiple displays
- windows
What you need:
DirectFB 1.0.1, 1.2.x, 1.3.0
Kernel-Framebuffer support: required: vesafb, radeonfb ....
Mesa 7.0.x - optional for OpenGL
/etc/directfbrc
This file should contain the following lines to make
your joystick work and avoid crashes:
------------------------
disable-module=joystick
disable-module=cle266
disable-module=cyber5k
no-linux-input-grab
------------------------
To disable to use x11 backend when DISPLAY variable is found use
export SDL_DIRECTFB_X11_CHECK=0
To disable the use of linux input devices, i.e. multimice/multikeyboard support,
use
export SDL_DIRECTFB_LINUX_INPUT=0
To use hardware accelerated YUV-overlays for YUV-textures, use:
export SDL_DIRECTFB_YUV_DIRECT=1
This is disabled by default. It will only support one
YUV texture, namely the first. Every other YUV texture will be
rendered in software.
In addition, you may use (directfb-1.2.x)
export SDL_DIRECTFB_YUV_UNDERLAY=1
to make the YUV texture an underlay. This will make the cursor to
be shown.
Simple Window Manager
=====================
The driver has support for a very, very basic window manager you may
want to use when running with "wm=default". Use
export SDL_DIRECTFB_WM=1
to enable basic window borders. In order to have the window title rendered,
you need to have the following font installed:
/usr/share/fonts/truetype/freefont/FreeSans.ttf
OpenGL Support
==============
The following instructions will give you *software* OpenGL. However this
works at least on all directfb supported platforms.
As of this writing 20100802 you need to pull Mesa from git and do the following:
------------------------
git clone git://anongit.freedesktop.org/git/mesa/mesa
cd mesa
git checkout 2c9fdaf7292423c157fc79b5ce43f0f199dd753a

===========================================================================
Dollar Gestures
===========================================================================
SDL Provides an implementation of the $1 gesture recognition system. This allows for recording, saving, loading, and performing single stroke gestures.
Gestures can be performed with any number of fingers (the centroid of the fingers must follow the path of the gesture), but the number of fingers must be constant (a finger cannot go down in the middle of a gesture). The path of a gesture is considered the path from the time when the final finger went down, to the first time any finger comes up.
Dollar gestures are assigned an Id based on a hash function. This is guaranteed to remain constant for a given gesture. There is a (small) chance that two different gestures will be assigned the same ID. In this case, simply re-recording one of the gestures should result in a different ID.
Recording:
----------
To begin recording on a touch device call:
SDL_RecordGesture(SDL_TouchID touchId), where touchId is the id of the touch device you wish to record on, or -1 to record on all connected devices.
Recording terminates as soon as a finger comes up. Recording is acknowledged by an SDL_DOLLARRECORD event.
A SDL_DOLLARRECORD event is a dgesture with the following fields:
event.dgesture.touchId - the Id of the touch used to record the gesture.
event.dgesture.gestureId - the unique id of the recorded gesture.
Performing:
-----------
As long as there is a dollar gesture assigned to a touch, every finger-up event will also cause an SDL_DOLLARGESTURE event with the following fields:
event.dgesture.touchId - the Id of the touch which performed the gesture.
event.dgesture.gestureId - the unique id of the closest gesture to the performed stroke.
event.dgesture.error - the difference between the gesture template and the actual performed gesture. Lower error is a better match.
event.dgesture.numFingers - the number of fingers used to draw the stroke.
Most programs will want to define an appropriate error threshold and check to be sure that the error of a gesture is not abnormally high (an indicator that no gesture was performed).
Saving:
-------
To save a template, call SDL_SaveDollarTemplate(gestureId, src) where gestureId is the id of the gesture you want to save, and src is an SDL_RWops pointer to the file where the gesture will be stored.
To save all currently loaded templates, call SDL_SaveAllDollarTemplates(src) where source is an SDL_RWops pointer to the file where the gesture will be stored.
Both functions return the number of gestures successfully saved.
Loading:
--------
To load templates from a file, call SDL_LoadDollarTemplates(touchId,src) where touchId is the id of the touch to load to (or -1 to load to all touch devices), and src is an SDL_RWops pointer to a gesture save file.
SDL_LoadDollarTemplates returns the number of templates successfully loaded.
===========================================================================
Multi Gestures
===========================================================================
SDL provides simple support for pinch/rotate/swipe gestures.
Every time a finger is moved an SDL_MULTIGESTURE event is sent with the following fields:
event.mgesture.touchId - the Id of the touch on which the gesture was performed.
event.mgesture.x - the normalized x coordinate of the gesture. (0..1)
event.mgesture.y - the normalized y coordinate of the gesture. (0..1)
event.mgesture.dTheta - the amount that the fingers rotated during this motion.
event.mgesture.dDist - the amount that the fingers pinched during this motion.
event.mgesture.numFingers - the number of fingers used in the gesture.

Building the Simple DirectMedia Layer for iPhone OS 2.0
==============================================================================
Requirements: Mac OS X v10.5 or later and the iPhone SDK.
Instructions:
1. Open SDL.xcodeproj (located in Xcode-iOS/SDL) in XCode.
2. Select your desired target, and hit build.
There are three build targets:
- libSDL.a:
Build SDL as a statically linked library
- testsdl
Build a test program (there are known test failures which are fine)
- Template:
Package a project template together with the SDL for iPhone static libraries and copies of the SDL headers. The template includes proper references to the SDL library and headers, skeleton code for a basic SDL program, and placeholder graphics for the application icon and startup screen.
==============================================================================
Build SDL for iOS from the command line
==============================================================================
1. cd (PATH WHERE THE SDL CODE IS)/build-scripts
2. ./iosbuild.sh
If everything goes fine, you should see a build/ios directory, inside there's
two directories "lib" and "include".
"include" contains a copy of the SDL headers that you'll need for your project,
make sure to configure XCode to look for headers there.
"lib" contains find two files, libSDL2.a and libSDL2main.a, you have to add both
to your XCode project. These libraries contain three architectures in them,
armv6 for legacy devices, armv7, and i386 (for the simulator).
By default, iosbuild.sh will autodetect the SDK version you have installed using
xcodebuild -showsdks, and build for iOS >= 3.0, you can override this behaviour
by setting the MIN_OS_VERSION variable, ie:
MIN_OS_VERSION=4.2 ./iosbuild.sh
==============================================================================
Using the Simple DirectMedia Layer for iOS
==============================================================================
FIXME: This needs to be updated for the latest methods
Here is the easiest method:
1. Build the SDL libraries (libSDL.a and libSDLSimulator.a) and the iPhone SDL Application template.
1. Install the iPhone SDL Application template by copying it to one of XCode's template directories. I recommend creating a directory called "SDL" in "/Developer/Platforms/iOS.platform/Developer/Library/XCode/Project Templates/" and placing it there.
2. Start a new project using the template. The project should be immediately ready for use with SDL.
Here is a more manual method:
1. Create a new iPhone view based application.
2. Build the SDL static libraries (libSDL.a and libSDLSimulator.a) for iPhone and include them in your project. XCode will ignore the library that is not currently of the correct architecture, hence your app will work both on iPhone and in the iPhone Simulator.
3. Include the SDL header files in your project.
4. Remove the ApplicationDelegate.h and ApplicationDelegate.m files -- SDL for iPhone provides its own UIApplicationDelegate. Remove MainWindow.xib -- SDL for iPhone produces its user interface programmatically.
5. Delete the contents of main.m and program your app as a regular SDL program instead. You may replace main.m with your own main.c, but you must tell XCode not to use the project prefix file, as it includes Objective-C code.
==============================================================================
Notes -- Application events
==============================================================================
On iOS the application goes through a fixed life cycle and you will get
notifications of state changes via application events. When these events
are delivered you must handle them in an event callback because the OS may
not give you any processing time after the events are delivered.
e.g.
int HandleAppEvents(void *userdata, SDL_Event *event)
{
switch (event->type)
{
case SDL_APP_TERMINATING:
/* Terminate the app.
Shut everything down before returning from this function.
*/
return 0;
case SDL_APP_LOWMEMORY:
/* You will get this when your app is paused and iOS wants more memory.
Release as much memory as possible.
*/
return 0;
case SDL_APP_WILLENTERBACKGROUND:
/* Prepare your app to go into the background. Stop loops, etc.
This gets called when the user hits the home button, or gets a call.
*/
return 0;
case SDL_APP_DIDENTERBACKGROUND:
/* This will get called if the user accepted whatever sent your app to the background.
If the user got a phone call and canceled it, you'll instead get an SDL_APP_DIDENTERFOREGROUND event and restart your loops.
When you get this, you have 5 seconds to save all your state or the app will be terminated.
Your app is NOT active at this point.
*/
return 0;
case SDL_APP_WILLENTERFOREGROUND:
/* This call happens when your app is coming back to the foreground.
Restore all your state here.
*/
return 0;
case SDL_APP_DIDENTERFOREGROUND:
/* Restart your loops here.
Your app is interactive and getting CPU again.
*/
return 0;
default:
/* No special processing, add it to the event queue */
return 1;
}
}
int main(int argc, char *argv[])
{
SDL_SetEventFilter(HandleAppEvents, NULL);
... run your main loop
return 0;
}

Notes -- Accelerometer as Joystick
==============================================================================
SDL for iPhone supports polling the built in accelerometer as a joystick device. For an example on how to do this, see the accelerometer.c in the demos directory.
The main thing to note when using the accelerometer with SDL is that while the iPhone natively reports accelerometer as floating point values in units of g-force, SDL_JoystickGetAxis reports joystick values as signed integers. Hence, in order to convert between the two, some clamping and scaling is necessary on the part of the iPhone SDL joystick driver. To convert SDL_JoystickGetAxis reported values BACK to units of g-force, simply multiply the values by SDL_IPHONE_MAX_GFORCE / 0x7FFF.
==============================================================================
Notes -- OpenGL ES
==============================================================================
Your SDL application for iPhone uses OpenGL ES for video by default.
OpenGL ES for iPhone supports several display pixel formats, such as RGBA8 and RGB565, which provide a 32 bit and 16 bit color buffer respectively. By default, the implementation uses RGB565, but you may use RGBA8 by setting each color component to 8 bits in SDL_GL_SetAttribute.
If your application doesn't use OpenGL's depth buffer, you may find significant performance improvement by setting SDL_GL_DEPTH_SIZE to 0.
Finally, if your application completely redraws the screen each frame, you may find significant performance improvement by setting the attribute SDL_GL_RETAINED_BACKING to 1.
==============================================================================
Notes -- Keyboard
==============================================================================
The SDL keyboard API has been extended to support on-screen keyboards:
void SDL_StartTextInput()
-- enables text events and reveals the onscreen keyboard.
void SDL_StopTextInput()
-- disables text events and hides the onscreen keyboard.
SDL_bool SDL_IsTextInputActive()
-- returns whether or not text events are enabled (and the onscreen keyboard is visible)
==============================================================================
Notes -- Reading and Writing files
==============================================================================
Each application installed on iPhone resides in a sandbox which includes its own Application Home directory. Your application may not access files outside this directory.
Once your application is installed its directory tree looks like:
MySDLApp Home/
MySDLApp.app
Documents/
Library/
Preferences/
tmp/
When your SDL based iPhone application starts up, it sets the working directory to the main bundle (MySDLApp Home/MySDLApp.app), where your application resources are stored. You cannot write to this directory. Instead, I advise you to write document files to "../Documents/" and preferences to "../Library/Preferences".
More information on this subject is available here:
http://developer.apple.com/library/ios/#documentation/iPhone/Conceptual/iPhoneOSProgrammingGuide/Introduction/Introduction.html
==============================================================================
Notes -- iPhone SDL limitations
==============================================================================
Windows:
Full-size, single window applications only. You cannot create multi-window SDL applications for iPhone OS. The application window will fill the display, though you have the option of turning on or off the menu-bar (pass SDL_CreateWindow the flag SDL_WINDOW_BORDERLESS).
Textures:
The optimal texture formats on iOS are SDL_PIXELFORMAT_ABGR8888, SDL_PIXELFORMAT_ABGR8888, SDL_PIXELFORMAT_BGR888, and SDL_PIXELFORMAT_RGB24 pixel formats.
Loading Shared Objects:
This is disabled by default since it seems to break the terms of the iPhone SDK agreement. It can be re-enabled in SDL_config_iphoneos.h.
==============================================================================
Game Center
==============================================================================
Game Center integration requires that you break up your main loop in order to yield control back to the system. In other words, instead of running an endless main loop, you run each frame in a callback function, using:
int SDL_iPhoneSetAnimationCallback(SDL_Window * window, int interval, void (*callback)(void*), void *callbackParam);
This will set up the given function to be called back on the animation callback, and then you have to return from main() to let the Cocoa event loop run.
e.g.
extern "C"
void ShowFrame(void*)
{
... do event handling, frame logic and rendering
}
int main(int argc, char *argv[])
{
... initialize game ...
#if __IPHONEOS__
// Initialize the Game Center for scoring and matchmaking
InitGameCenter();
// Set up the game to run in the window animation callback on iOS
// so that Game Center and so forth works correctly.
SDL_iPhoneSetAnimationCallback(window, 1, ShowFrame, NULL);
#else
while ( running ) {
ShowFrame(0);
DelayFrame();
}
#endif
return 0;
}

==============================================================================
Using the Simple DirectMedia Layer with Mac OS X
==============================================================================
These instructions are for people using Apple's Mac OS X (pronounced
"ten").
From the developer's point of view, OS X is a sort of hybrid Mac and
Unix system, and you have the option of using either traditional
command line tools or Apple's IDE Xcode.
To build SDL using the command line, use the standard configure and make
process:
./configure
make
sudo make install
You can also build SDL as a Universal library (a single binary for both
PowerPC and Intel architectures), on Mac OS X 10.4 and newer, by using
the fatbuild.sh script in build-scripts:
sh build-scripts/fatbuild.sh
sudo build-scripts/fatbuild.sh install
This script builds SDL with 10.2 ABI compatibility on PowerPC and 10.4
ABI compatibility on Intel architectures. For best compatibility you
should compile your application the same way. A script which wraps
gcc to make this easy is provided in test/gcc-fat.sh
To use the library once it's built, you essential have two possibilities:
use the traditional autoconf/automake/make method, or use Xcode.
==============================================================================
Using the Simple DirectMedia Layer with a traditional Makefile
==============================================================================
An existing autoconf/automake build system for your SDL app has good chances
to work almost unchanged on OS X. However, to produce a "real" Mac OS X binary
that you can distribute to users, you need to put the generated binary into a
so called "bundle", which basically is a fancy folder with a name like
"MyCoolGame.app".
To get this build automatically, add something like the following rule to
your Makefile.am:
bundle_contents = APP_NAME.app/Contents
APP_NAME_bundle: EXE_NAME
mkdir -p $(bundle_contents)/MacOS
mkdir -p $(bundle_contents)/Resources
echo "APPL????" > $(bundle_contents)/PkgInfo
$(INSTALL_PROGRAM) $< $(bundle_contents)/MacOS/
You should replace EXE_NAME with the name of the executable. APP_NAME is what
will be visible to the user in the Finder. Usually it will be the same
as EXE_NAME but capitalized. E.g. if EXE_NAME is "testgame" then APP_NAME
usually is "TestGame". You might also want to use @PACKAGE@ to use the package
name as specified in your configure.in file.
If your project builds more than one application, you will have to do a bit
more. For each of your target applications, you need a separate rule.
If you want the created bundles to be installed, you may want to add this
rule to your Makefile.am:
install-exec-hook: APP_NAME_bundle
rm -rf $(DESTDIR)$(prefix)/Applications/APP_NAME.app
mkdir -p $(DESTDIR)$(prefix)/Applications/
cp -r $< /$(DESTDIR)$(prefix)Applications/
This rule takes the Bundle created by the rule from step 3 and installs them
into $(DESTDIR)$(prefix)/Applications/.
Again, if you want to install multiple applications, you will have to augment
the make rule accordingly.
But beware! That is only part of the story! With the above, you end up with
a bare bone .app bundle, which is double clickable from the Finder. But
there are some more things you should do before shipping your product...
1) The bundle right now probably is dynamically linked against SDL. That
means that when you copy it to another computer, *it will not run*,
unless you also install SDL on that other computer. A good solution
for this dilemma is to static link against SDL. On OS X, you can
achieve that by linking against the libraries listed by
sdl-config --static-libs
instead of those listed by
sdl-config --libs
Depending on how exactly SDL is integrated into your build systems, the
way to achieve that varies, so I won't describe it here in detail
2) Add an 'Info.plist' to your application. That is a special XML file which
contains some meta-information about your application (like some copyright
information, the version of your app, the name of an optional icon file,
and other things). Part of that information is displayed by the Finder
when you click on the .app, or if you look at the "Get Info" window.
More information about Info.plist files can be found on Apple's homepage.
As a final remark, let me add that I use some of the techniques (and some
variations of them) in Exult and ScummVM; both are available in source on
the net, so feel free to take a peek at them for inspiration!
==============================================================================
Using the Simple DirectMedia Layer with Xcode
==============================================================================
These instructions are for using Apple's Xcode IDE to build SDL applications.
- First steps
The first thing to do is to unpack the Xcode.tar.gz archive in the
top level SDL directory (where the Xcode.tar.gz archive resides).
Because Stuffit Expander will unpack the archive into a subdirectory,
you should unpack the archive manually from the command line:
cd [path_to_SDL_source]
tar zxf Xcode.tar.gz
This will create a new folder called Xcode, which you can browse
normally from the Finder.
- Building the Framework
The SDL Library is packaged as a framework bundle, an organized
relocatable folder hierarchy of executable code, interface headers,
and additional resources. For practical purposes, you can think of a
framework as a more user and system-friendly shared library, whose library
file behaves more or less like a standard UNIX shared library.
To build the framework, simply open the framework project and build it.
By default, the framework bundle "SDL.framework" is installed in
/Library/Frameworks. Therefore, the testers and project stationary expect
it to be located there. However, it will function the same in any of the
following locations:
~/Library/Frameworks
/Local/Library/Frameworks
/System/Library/Frameworks
- Build Options
There are two "Build Styles" (See the "Targets" tab) for SDL.
"Deployment" should be used if you aren't tweaking the SDL library.
"Development" should be used to debug SDL apps or the library itself.
- Building the Testers
Open the SDLTest project and build away!
- Using the Project Stationary
Copy the stationary to the indicated folders to access it from
the "New Project" and "Add target" menus. What could be easier?
- Setting up a new project by hand
Some of you won't want to use the Stationary so I'll give some tips:
* Create a new "Cocoa Application"
* Add src/main/macosx/SDLMain.m , .h and .nib to your project
* Remove "main.c" from your project
* Remove "MainMenu.nib" from your project
* Add "$(HOME)/Library/Frameworks/SDL.framework/Headers" to include path
* Add "$(HOME)/Library/Frameworks" to the frameworks search path
* Add "-framework SDL -framework Foundation -framework AppKit" to "OTHER_LDFLAGS"
* Set the "Main Nib File" under "Application Settings" to "SDLMain.nib"
* Add your files
* Clean and build
- Building from command line
Use pbxbuild in the same directory as your .pbproj file
- Running your app
You can send command line args to your app by either invoking it from
the command line (in *.app/Contents/MacOS) or by entering them in the
"Executables" panel of the target settings.
- Implementation Notes
Some things that may be of interest about how it all works...
* Working directory
As defined in the SDL_main.m file, the working directory of your SDL app
is by default set to its parent. You may wish to change this to better
suit your needs.
* You have a Cocoa App!
Your SDL app is essentially a Cocoa application. When your app
starts up and the libraries finish loading, a Cocoa procedure is called,
which sets up the working directory and calls your main() method.
You are free to modify your Cocoa app with generally no consequence
to SDL. You cannot, however, easily change the SDL window itself.
Functionality may be added in the future to help this.

SDL 2.0 with open pandora console support ( http://openpandora.org/ )
=====================================================================
- A pandora specific video driver was written to allow SDL 2.0 with OpenGL ES
support to work on the pandora under the framebuffer. This driver do not have
input support for now, so if you use it you will have to add your own control code.
The video driver name is "pandora" so if you have problem running it from
the framebuffer, try to set the following variable before starting your application :
"export SDL_VIDEODRIVER=pandora"
- OpenGL ES support was added to the x11 driver, so it's working like the normal
x11 driver one with OpenGLX support, with SDL input event's etc..

* Porting To A New Platform
The first thing you have to do when porting to a new platform, is look at
include/SDL_platform.h and create an entry there for your operating system.
The standard format is __PLATFORM__, where PLATFORM is the name of the OS.
Ideally SDL_platform.h will be able to auto-detect the system it's building
on based on C preprocessor symbols.
There are two basic ways of building SDL at the moment:
1. The "UNIX" way: ./configure; make; make install
If you have a GNUish system, then you might try this. Edit configure.in,
take a look at the large section labelled:
"Set up the configuration based on the target platform!"
Add a section for your platform, and then re-run autogen.sh and build!
2. Using an IDE:
If you're using an IDE or other non-configure build system, you'll probably
want to create a custom SDL_config.h for your platform. Edit SDL_config.h,
add a section for your platform, and create a custom SDL_config_{platform}.h,
based on SDL_config.h.minimal and SDL_config.h.in
Add the top level include directory to the header search path, and then add
the following sources to the project:
src/*.c
src/atomic/*.c
src/audio/*.c
src/cpuinfo/*.c
src/events/*.c
src/file/*.c
src/haptic/*.c
src/joystick/*.c
src/power/*.c
src/render/*.c
src/stdlib/*.c
src/thread/*.c
src/timer/*.c
src/video/*.c
src/audio/disk/*.c
src/audio/dummy/*.c
src/video/dummy/*.c
src/haptic/dummy/*.c
src/joystick/dummy/*.c
src/main/dummy/*.c
src/thread/generic/*.c
src/timer/dummy/*.c
src/loadso/dummy/*.c
Once you have a working library without any drivers, you can go back to each
of the major subsystems and start implementing drivers for your platform.
If you have any questions, don't hesitate to ask on the SDL mailing list:
http://www.libsdl.org/mailing-list.php
Enjoy!

===========================================================================
System Specific Notes
===========================================================================
Linux:
The linux touch system is currently based off event streams, and proc/bus/devices. The active user must be given permissions to read /dev/input/TOUCHDEVICE, where TOUCHDEVICE is the event stream for your device. Currently only Wacom tablets are supported. If you have an unsupported tablet contact me at jim.tla+sdl_touch@gmail.com and I will help you get support for it.
Mac:
The Mac and iPhone APIs are pretty. If your touch device supports them then you'll be fine. If it doesn't, then there isn't much we can do.
iPhone:
Works out of box.
Windows:
Unfortunately there is no windows support as of yet. Support for Windows 7 is planned, but we currently have no way to test. If you have a Windows 7 WM_TOUCH supported device, and are willing to help test please contact me at jim.tla+sdl_touch@gmail.com
===========================================================================
Events
===========================================================================
SDL_FINGERDOWN:
Sent when a finger (or stylus) is placed on a touch device.
Fields:
event.tfinger.touchId - the Id of the touch device.
event.tfinger.fingerId - the Id of the finger which just went down.
event.tfinger.x - the x coordinate of the touch (0..1)
event.tfinger.y - the y coordinate of the touch (0..1)
event.tfinger.pressure - the pressure of the touch (0..1)
SDL_FINGERMOTION:
Sent when a finger (or stylus) is moved on the touch device.
Fields:
Same as SDL_FINGERDOWN but with additional:
event.tfinger.dx - change in x coordinate during this motion event.
event.tfinger.dy - change in y coordinate during this motion event.
SDL_FINGERUP:
Sent when a finger (or stylus) is lifted from the touch device.
Fields:
Same as SDL_FINGERDOWN.
===========================================================================
Functions
===========================================================================
SDL provides the ability to access the underlying Finger structures.
These structures should _never_ be modified.
The following functions are included from SDL_touch.h
To get a SDL_TouchID call SDL_GetTouchDevice(index).
This returns a SDL_TouchID.
IMPORTANT: If the touch has been removed, or there is no touch with the given ID, SDL_GetTouchID will return 0. Be sure to check for this!
The number of touch devices can be queried with SDL_GetNumTouchDevices().
A SDL_TouchID may be used to get pointers to SDL_Finger.
SDL_GetNumTouchFingers(touchID) may be used to get the number of fingers currently down on the device.
The most common reason to access SDL_Finger is to query the fingers outside the event. In most cases accessing the fingers is using the event. This would be accomplished by code like the following:
float x = event.tfinger.x;
float y = event.tfinger.y;
To get a SDL_Finger, call SDL_GetTouchFinger(touchID,index), where touchID is a SDL_TouchID, and index is the requested finger.
This returns a SDL_Finger*, or NULL if the finger does not exist, or has been removed.
A SDL_Finger is guaranteed to be persistent for the duration of a touch, but it will be de-allocated as soon as the finger is removed. This occurs when the SDL_FINGERUP event is _added_ to the event queue, and thus _before_ the SDL_FINGERUP event is polled.
As a result, be very careful to check for NULL return values.
A SDL_Finger has the following fields:
>x,y,pressure:
The current coordinates of the touch.
>pressure:
The pressure of the touch.

SDL on DirectFB
Supports:
- Hardware YUV overlays
- OpenGL - software only
- 2D/3D accelerations (depends on directfb driver)
- multiple displays
- windows
What you need:
DirectFB 1.0.1, 1.2.x, 1.3.0
Kernel-Framebuffer support: required: vesafb, radeonfb ....
Mesa 7.0.x - optional for OpenGL
/etc/directfbrc
This file should contain the following lines to make
your joystick work and avoid crashes:
------------------------
disable-module=joystick
disable-module=cle266
disable-module=cyber5k
no-linux-input-grab
------------------------
To disable to use x11 backend when DISPLAY variable is found use
export SDL_DIRECTFB_X11_CHECK=0
To disable the use of linux input devices, i.e. multimice/multikeyboard support,
use
export SDL_DIRECTFB_LINUX_INPUT=0
To use hardware accelerated YUV-overlays for YUV-textures, use:
export SDL_DIRECTFB_YUV_DIRECT=1
This is disabled by default. It will only support one
YUV texture, namely the first. Every other YUV texture will be
rendered in software.
In addition, you may use (directfb-1.2.x)
export SDL_DIRECTFB_YUV_UNDERLAY=1
to make the YUV texture an underlay. This will make the cursor to
be shown.
Simple Window Manager
=====================
The driver has support for a very, very basic window manager you may
want to use when runnning with "wm=default". Use
export SDL_DIRECTFB_WM=1
to enable basic window borders. In order to have the window title rendered,
you need to have the following font installed:
/usr/share/fonts/truetype/freefont/FreeSans.ttf
OPENGL Support
==============
The following instructions will give you *software* opengl. However this
works at least on all directfb supported platforms.

framework as a more user and system-friendly shared library, whose library
file behaves more or less like a standard UNIX shared library.
To build the framework, simply open the framework project and build it.
By default, the framework bundle "SDL.framework" is installed in
/Library/Frameworks. Therefore, the testers and project stationary expect
it to be located there. However, it will function the same in any of the
following locations:
~/Library/Frameworks
/Local/Library/Frameworks
/System/Library/Frameworks
- Build Options
There are two "Build Styles" (See the "Targets" tab) for SDL.
"Deployment" should be used if you aren't tweaking the SDL library.
"Development" should be used to debug SDL apps or the library itself.
- Building the Testers
Open the SDLTest project and build away!
- Using the Project Stationary
Copy the stationary to the indicated folders to access it from
the "New Project" and "Add target" menus. What could be easier?
- Setting up a new project by hand
Some of you won't want to use the Stationary so I'll give some tips:
* Create a new "Cocoa Application"
* Add src/main/macosx/SDLMain.m , .h and .nib to your project
* Remove "main.c" from your project
* Remove "MainMenu.nib" from your project
* Add "$(HOME)/Library/Frameworks/SDL.framework/Headers" to include path
* Add "$(HOME)/Library/Frameworks" to the frameworks search path
* Add "-framework SDL -framework Foundation -framework AppKit" to "OTHER_LDFLAGS"
* Set the "Main Nib File" under "Application Settings" to "SDLMain.nib"
* Add your files
* Clean and build
- Building from command line
Use pbxbuild in the same directory as your .pbproj file
- Running your app
You can send command line args to your app by either invoking it from
the command line (in *.app/Contents/MacOS) or by entering them in the
"Executibles" panel of the target settings.
- Implementation Notes
Some things that may be of interest about how it all works...
* Working directory
As defined in the SDL_main.m file, the working directory of your SDL app
is by default set to its parent. You may wish to change this to better
suit your needs.
* You have a Cocoa App!
Your SDL app is essentially a Cocoa application. When your app
starts up and the libraries finish loading, a Cocoa procedure is called,
which sets up the working directory and calls your main() method.
You are free to modify your Cocoa app with generally no consequence
to SDL. You cannot, however, easily change the SDL window itself.
Functionality may be added in the future to help this.

* Porting To A New Platform
The first thing you have to do when porting to a new platform, is look at
include/SDL_platform.h and create an entry there for your operating system.
The standard format is __PLATFORM__, where PLATFORM is the name of the OS.
Ideally SDL_platform.h will be able to auto-detect the system it's building
on based on C preprocessor symbols.
There are two basic ways of building SDL at the moment:
1. The "UNIX" way: ./configure; make; make install
If you have a GNUish system, then you might try this. Edit configure.in,
take a look at the large section labelled:
"Set up the configuration based on the target platform!"
Add a section for your platform, and then re-run autogen.sh and build!
2. Using an IDE:
If you're using an IDE or other non-configure build system, you'll probably
want to create a custom SDL_config.h for your platform. Edit SDL_config.h,
add a section for your platform, and create a custom SDL_config_{platform}.h,
based on SDL_config.h.minimal and SDL_config.h.in
Add the top level include directory to the header search path, and then add
the following sources to the project:
src/*.c
src/audio/*.c
src/cdrom/*.c
src/cpuinfo/*.c
src/events/*.c
src/file/*.c
src/joystick/*.c
src/stdlib/*.c
src/thread/*.c
src/timer/*.c
src/video/*.c
src/audio/disk/*.c
src/audio/dummy/*.c
src/video/dummy/*.c
src/joystick/dummy/*.c
src/cdrom/dummy/*.c
src/thread/generic/*.c
src/timer/dummy/*.c
src/loadso/dummy/*.c
Once you have a working library without any drivers, you can go back to each
of the major subsystems and start implementing drivers for your platform.
If you have any questions, don't hesitate to ask on the SDL mailing list:
http://www.libsdl.org/mailing-list.php
Enjoy!

- all possible WinCE devices (Pocket PC, Smartphones, HPC)
with different orientations of video memory and resolutions.
- 4, 8 and 16 bpp devices
- special handling of 8bpp on 8bpp devices
- VGA mode, you can even switch between VGA and GAPI in runtime

================================================================================
Simple DirectMedia Layer for Android
================================================================================
Requirements:
Android SDK
http://developer.android.com/sdk/index.html
Android NDK r4 or later
http://developer.android.com/sdk/ndk/index.html
================================================================================
How the port works
================================================================================
- Android applications are Java-based, optionally with parts written in C
- As SDL apps are C-based, we use a small Java shim that uses JNI to talk to
the SDL library
- This means that your application C code must be placed inside an android
Java project, along with some C support code that communicates with Java
- This eventually produces a standard Android .apk package
The Android Java code implements an "activity" and can be found in:
android-project/src/org/libsdl/app/SDLActivity.java
The Java code loads your game code, the SDL shared library, and
dispatches to native functions implemented in the SDL library:
src/SDL_android.cpp
Your project must include some glue code that starts your main() routine:
src/main/android/SDL_android_main.cpp
================================================================================
Building an app
================================================================================
Instructions:
1. Copy the android-project directory wherever you want to keep your projects and rename it to the name of your project.
2. Move this SDL directory into the <project>/jni directory and then copy
SDL_config_android.h to SDL_config.h inside the include folder
3. Place your application source files in the <project>/jni/src directory
4. Edit <project>/jni/src/Android.mk to include your source files
5. Run 'ndk-build' (a script provided by the NDK). This compiles the C source
If you want to use the Eclipse IDE, skip to the Eclipse section below.
6. Edit <project>/local.properties to point to the Android SDK directory
7. Run 'ant debug' in android/project. This compiles the .java and eventually
creates a .apk with the native code embedded
8. 'ant install' will push the apk to the device or emulator (if connected)
Here's an explanation of the files in the Android project, so you can customize them:
android-project/
AndroidManifest.xml - package manifest, do not modify
build.properties - empty
build.xml - build description file, used by ant
default.properties - holds the ABI for the application, currently android-4 which corresponds to the Android 1.6 system image
local.properties - holds the SDK path, you should change this to the path to your SDK
jni/ - directory holding native code
jni/Android.mk - Android makefile that includes all subdirectories
jni/SDL/ - directory holding the SDL library files
jni/SDL/Android.mk - Android makefile for creating the SDL shared library
jni/src/ - directory holding your C/C++ source
jni/src/Android.mk - Android makefile that you should customize to include your source code and any library references
res/ - directory holding resources for your application
res/drawable-* - directories holding icons for different phone hardware
res/layout/main.xml - place holder for the main screen layout, overridden by the SDL video output
res/values/strings.xml - strings used in your application, including the application name shown on the phone.
src/org/libsdl/app/SDLActivity.java - the Java class handling the initialization and binding to SDL. Be very careful changing this, as the SDL library relies on this implementation.
================================================================================
Additional documentation
================================================================================
The documentation in the NDK docs directory is very helpful in understanding the build process and how to work with native code on the Android platform.
The best place to start is with docs/OVERVIEW.TXT
================================================================================
Using Eclipse
================================================================================
First make sure that you've installed Eclipse and the Android extensions as described here:
http://developer.android.com/sdk/eclipse-adt.html
Once you've copied the SDL android project and customized it, you can create an Eclipse project from it:
* File -> New -> Other
* Select the Android -> Android Project wizard and click Next
* Enter the name you'd like your project to have
* Select "Create project from existing source" and browse for your project directory
* Make sure the Build Target is set to Android 1.6
* Click Finish
================================================================================
Loading files and resources
================================================================================
NEED CONTENT
================================================================================
Troubleshooting
================================================================================
You can create and run an emulator from the Eclipse IDE:
* Window -> Android SDK and AVD Manager
You can see if adb can see any devices with the following command:
adb devices
You can see the output of log messages on the default device with:
adb logcat
You can push files to the device with:
adb push local_file remote_path_and_file
You can push files to the SD Card at /sdcard, for example:
adb push moose.dat /sdcard/moose.dat
You can see the files on the SD card with a shell command:
adb shell ls /sdcard/
You can start a command shell on the default device with:
adb shell
You can do a clean build with the following commands:
ndk-build clean
ndk-build
You can see the complete command line that ndk-build is using by passing V=1 on the command line:
ndk-build V=1
If your application crashes in native code, you can use addr2line to convert the addresses in the stack trace to lines in your code.
For example, if your crash looks like this:
I/DEBUG ( 31): signal 11 (SIGSEGV), code 2 (SEGV_ACCERR), fault addr 400085d0
I/DEBUG ( 31): r0 00000000 r1 00001000 r2 00000003 r3 400085d4
I/DEBUG ( 31): r4 400085d0 r5 40008000 r6 afd41504 r7 436c6a7c
I/DEBUG ( 31): r8 436c6b30 r9 435c6fb0 10 435c6f9c fp 4168d82c
I/DEBUG ( 31): ip 8346aff0 sp 436c6a60 lr afd1c8ff pc afd1c902 cpsr 60000030
I/DEBUG ( 31): #00 pc 0001c902 /system/lib/libc.so
I/DEBUG ( 31): #01 pc 0001ccf6 /system/lib/libc.so
I/DEBUG ( 31): #02 pc 000014bc /data/data/org.libsdl.app/lib/libmain.so
I/DEBUG ( 31): #03 pc 00001506 /data/data/org.libsdl.app/lib/libmain.so
You can see that there's a crash in the C library being called from the main code. I run addr2line with the debug version of my code:
arm-eabi-addr2line -C -f -e obj/local/armeabi/libmain.so
and then paste in the number after "pc" in the call stack, from the line that I care about:
000014bc
I get output from addr2line showing that it's in the quit function, in testspriteminimal.c, on line 23.
You can add logging to your code to help show what's happening:
#include <android/log.h>
__android_log_print(ANDROID_LOG_INFO, "foo", "Something happened! x = %d", x);
If you need to build without optimization turned on, you can create a file called "Application.mk" in the jni directory, with the following line in it:
APP_OPTIM := debug
================================================================================
Known issues
================================================================================
- SDL audio (although it's mostly written, just not working properly yet)
- TODO. I'm sure there's a bunch more stuff I haven't thought of

Simple DirectMedia Layer for Nintendo DS
================================================================================
-Requirements-
* The devkitpro SDK available at http://devkitpro.org.
Read the information at http://devkitpro.org/wiki/Getting_Started/devkitARM
The necessary packages are devkitARM, libnds, libfat and default arm7.
* Optionally, use a DS emulator, such as desmume (http://desmume.org/)
to program and debug.
-Building SDL-
After setting the devkitpro environment, cd into your SDL directory and type:
make -f Makefile.ds
This will compile and install the library and headers into the
devkitpro's portlibs directory (../portlibs/arm/lib/ and
../portlibs/arm/include/). Additionally it will compile several tests
that you can run either on the DS or with desmume. For instance:
desmume --cflash-path=test/ test/nds-test-progs/testsprite2/testsprite2.nds
desmume --cflash-path=test/ test/nds-test-progs/testspriteminimal/testspriteminimal.nds
desmume --cflash-path=test/ test/nds-test-progs/testscale/testscale.nds
desmume test/nds-test-progs/general/general.nds
-Notes-
* The renderer code is based on the gl like engine. It's not using the sprite engine.
* The hardware renderer is using the parts of the libgl2d abstraction library that can be found at:
http://rel.phatcode.net/junk.php?id=117
Used with the author's permission.
* The port is very basic and incomplete:
- SDL currently has to be compiled for either framebuffer mode or renderer mode.
See USE_HW_RENDERER in Makefile.ds.
- some optional renderer functions are not implemented.
- no sound
-Limitations-
* in hardware renderer mode, don't load too many textures. The internal format is
2 bytes per pixel. And there is only 256KB reserved for the textures. For instance,
testscale won't display sample.bmp, unless it's resized to a smaller picture.
* the screen size is 256 x 384. Anything else won't work.
* there is no 8 bits/pixel mode because SDL 2.0 doesn't support palettes.
-Joystick mapping-
The Joystick presented to SDL has 2 axes and 8 buttons
KEY | Code
A | 0
B | 1
X | 2
Y | 3
L | 4
R | 5
select | 6
start | 7
Left-right is axe 0.
Up-down is axe 1.
-Mouse mapping-
todo
-Examples-
Due to memory limitations, to be able to successfully run the testscale example, sample.bmp must be resized to 256x105.

===========================================================================
Dollar Gestures
===========================================================================
SDL Provides an implementation of the $1 gesture recognition system. This allows for recording, saving, loading, and performing single stroke gestures.
Gestures can be performed with any number of fingers (the centroid of the fingers must follow the path of the gesture), but the number of fingers must be constant (a finger cannot go down in the middle of a gesture). The path of a gesture is considered the path from the time when the final finger went down, to the first time any finger comes up.
Dollar gestures are assigned an Id based on a hash function. This is guaranteed to remain constant for a given gesture. There is a (small) chance that two different gestures will be assigned the same ID. In this case, simply re-recording one of the gestures should result in a different ID.
Recording:
----------
To begin recording on a touch device call:
SDL_RecordGesture(SDL_TouchID touchId), where touchId is the id of the touch device you wish to record on, or -1 to record on all connected devices.
Recording terminates as soon as a finger comes up. Recording is acknowledged by an SDL_DOLLARRECORD event.
A SDL_DOLLARRECORD event is a dgesture with the following fields:
event.dgesture.touchId - the Id of the touch used to record the gesture.
event.dgesture.gestureId - the unique id of the recoreded gesture.
Performing:
-----------
As long as there is a dollar gesture assigned to a touch, every finger-up event will also cause an SDL_DOLLARGESTURE event with the following fields:
event.dgesture.touchId - the Id of the touch which performed the gesture.
event.dgesture.gestureId - the unique id of the closest gesture to the performed stroke.
event.dgesture.error - the difference between the gesture template and the actual performed gesture. Lower error is a better match.
event.dgesture.numFingers - the number of fingers used to draw the stroke.
Most programs will want to define an appropriate error threshold and check to be sure taht the error of a gesture is not abnormally high (an indicator that no gesture was performed).
Saving:
-------
To save a template, call SDL_SaveDollarTemplate(gestureId, src) where gestureId is the id of the gesture you want to save, and src is an SDL_RWops pointer to the file where the gesture will be stored.
To save all currently loaded templates, call SDL_SaveAllDollarTemplates(src) where source is an SDL_RWops pointer to the file where the gesture will be stored.
Both functions return the number of gestures sucessfully saved.
Loading:
--------
To load templates from a file, call SDL_LoadDollarTemplates(touchId,src) where touchId is the id of the touch to load to (or -1 to load to all touch devices), and src is an SDL_RWops pointer to a gesture save file.
SDL_LoadDollarTemplates returns the number of templates sucessfully loaded.
===========================================================================
Multi Gestures
===========================================================================
SDL provides simple support for pinch/rotate/swipe gestures.
Every time a finger is moved an SDL_MULTIGESTURE event is sent with the following fields:
event.mgesture.touchId - the Id of the touch on which the gesture was performed.
event.mgesture.x - the normalized x cooridinate of the gesture. (0..1)
event.mgesture.y - the normalized y cooridinate of the gesture. (0..1)
event.mgesture.dTheta - the amount that the fingers rotated during this motion.
event.mgesture.dDist - the amount that the fingers pinched during this motion.
event.mgesture.numFingers - the number of fingers used in the gesture.

Building the Simple DirectMedia Layer for iPhone OS 2.0
==============================================================================
Requirements: Mac OS X v10.5 or later and the iPhone SDK.
Instructions:
1. Open SDL.xcodeproj (located in Xcode-iOS/SDL) in XCode.
2. Select your desired target, and hit build.
There are three build targets:
- libSDL.a:
Build SDL as a statically linked library
- testsdl
Build a test program (there are known test failures which are fine)
- Template:
Package a project template together with the SDL for iPhone static libraries and copies of the SDL headers. The template includes proper references to the SDL library and headers, skeleton code for a basic SDL program, and placeholder graphics for the application icon and startup screen.
==============================================================================
Using the Simple DirectMedia Layer for iOS
==============================================================================
FIXME: This needs to be updated for the latest methods
Here is the easiest method:
1. Build the SDL libraries (libSDL.a and libSDLSimulator.a) and the iPhone SDL Application template.
1. Install the iPhone SDL Application template by copying it to one of XCode's template directories. I recommend creating a directory called "SDL" in "/Developer/Platforms/iOS.platform/Developer/Library/XCode/Project Templates/" and placing it there.
2. Start a new project using the template. The project should be immediately ready for use with SDL.
Here is a more manual method:
1. Create a new iPhone view based application.
2. Build the SDL static libraries (libSDL.a and libSDLSimulator.a) for iPhone and include them in your project. XCode will ignore the library that is not currently of the correct architecture, hence your app will work both on iPhone and in the iPhone Simulator.
3. Include the SDL header files in your project.
4. Remove the ApplicationDelegate.h and ApplicationDelegate.m files -- SDL for iPhone provides its own UIApplicationDelegate. Remove MainWindow.xib -- SDL for iPhone produces its user interface programmatically.
5. Delete the contents of main.m and program your app as a regular SDL program instead. You may replace main.m with your own main.c, but you must tell XCode not to use the project prefix file, as it includes Objective-C code.
==============================================================================
Notes -- Accelerometer as Joystick
==============================================================================
SDL for iPhone supports polling the built in accelerometer as a joystick device. For an example on how to do this, see the accelerometer.c in the demos directory.
The main thing to note when using the accelerometer with SDL is that while the iPhone natively reports accelerometer as floating point values in units of g-force, SDL_JoystickGetAxis reports joystick values as signed integers. Hence, in order to convert between the two, some clamping and scaling is necessary on the part of the iPhone SDL joystick driver. To convert SDL_JoystickGetAxis reported values BACK to units of g-force, simply multiply the values by SDL_IPHONE_MAX_GFORCE / 0x7FFF.
==============================================================================
Notes -- OpenGL ES
==============================================================================
Your SDL application for iPhone uses OpenGL ES for video by default.
OpenGL ES for iPhone supports several display pixel formats, such as RGBA8 and RGB565, which provide a 32 bit and 16 bit color buffer respectively. By default, the implementation uses RGB565, but you may use RGBA8 by setting each color component to 8 bits in SDL_GL_SetAttribute.
If your application doesn't use OpenGL's depth buffer, you may find significant performance improvement by setting SDL_GL_DEPTH_SIZE to 0.
Finally, if your application completely redraws the screen each frame, you may find significant performance improvement by setting the attribute SDL_GL_RETAINED_BACKING to 1.
==============================================================================
Notes -- Keyboard
==============================================================================
SDL for iPhone contains several additional functions related to keyboard visibility. These functions are not part of the SDL standard API, but are necessary for revealing and hiding the iPhone's virtual onscreen keyboard. You can use them in your own applications by including a copy of the SDL_uikitkeyboard.h header (located in src/video/uikit) in your project.
int SDL_iPhoneKeyboardShow(SDL_Window * window)
-- reveals the onscreen keyboard. Returns 0 on success and -1 on error.
int SDL_iPhoneKeyboardHide(SDL_Window * window)
-- hides the onscreen keyboard. Returns 0 on success and -1 on error.
SDL_bool SDL_iPhoneKeyboardIsShown(SDL_Window * window)
-- returns whether or not the onscreen keyboard is currently visible.
int SDL_iPhoneKeyboardToggle(SDL_Window * window)
-- toggles the visibility of the onscreen keyboard. Returns 0 on success and -1 on error.
==============================================================================
Notes -- Reading and Writing files
==============================================================================
Each application installed on iPhone resides in a sandbox which includes its own Application Home directory. Your application may not access files outside this directory.
Once your application is installed its directory tree looks like:
MySDLApp Home/
MySDLApp.app
Documents/
Library/
Preferences/
tmp/
When your SDL based iPhone application starts up, it sets the working directory to the main bundle (MySDLApp Home/MySDLApp.app), where your application resources are stored. You cannot write to this directory. Instead, I advise you to write document files to "../Documents/" and preferences to "../Library/Preferences".
More information on this subject is available here:
http://developer.apple.com/library/ios/#documentation/iPhone/Conceptual/iPhoneOSProgrammingGuide/Introduction/Introduction.html
==============================================================================
Notes -- iPhone SDL limitations
==============================================================================
Windows:
Full-size, single window applications only. You cannot create multi-window SDL applications for iPhone OS. The application window will fill the display, though you have the option of turning on or off the menu-bar (pass SDL_CreateWindow the flag SDL_WINDOW_BORDERLESS). Presently, landscape mode is not supported.
Video:
For real time frame-rates, you are advised to use strictly SDL 2.0 video calls. Using compatibility video calls uploads an OpenGL texture for each frame drawn, and this operation is excruciatingly slow.
Textures:
SDL for iPhone Textures supports only SDL_PIXELFORMAT_ABGR8888 and SDL_PIXELFORMAT_RGB24 pixel formats. This is because texture support in SDL for iPhone is done through OpenGL ES, which supports fewer pixel formats than OpenGL, will not re-order pixel data for you, and has no support for color-paletted formats (without extensions).
Audio:
SDL for iPhone does not yet support audio input.
Loading Shared Objects:
This is disabled by default since it seems to break the terms of the iPhone SDK agreement. It can be re-enabled in SDL_config_iphoneos.h.

- A pandora specific video driver was writed to allow SDL 2.0 with OpenGL ES
support to work on the pandora under the framebuffer. This driver do not have
input support for now, so if you use it you will have to add your own control code.
The video driver name is "pandora" so if you have problem running it from
the framebuffer, try to set the following variable before starting your application :
"export SDL_VIDEODRIVER=pandora"
- OpenGL ES support was added to the x11 driver, so it's working like the normal

System Specific Notes
===========================================================================
Linux:
The linux touch system is currently based off event streams, and proc/bus/devices. The active user must be given permissions to read /dev/input/TOUCHDEVICE, where TOUCHDEVICE is the event stream for your device. Currently only Wacom tablets are supported. If you have an unsupported tablet contact me at jim.tla+sdl_touch@gmail.com and I will help you get support for it.
Mac:
The Mac and Iphone API's are pretty. If your touch device supports them then you'll be fine. If it doesn't, then there isn't much we can do.
iPhone:
Works out of box.
Windows:
Unfortunately there is no windows support as of yet. Support for Windows 7 is planned, but we currently have no way to test. If you have a Windows 7 WM_TOUCH supported device, and are willing to help test please contact me at jim.tla+sdl_touch@gmail.com

===========================================================================
SDL_FINGERDOWN:
Sent when a finger (or stylus) is placed on a touch device.
Fields:
event.tfinger.touchId - the Id of the touch device.
event.tfinger.fingerId - the Id of the finger which just went down.
event.tfinger.x - the x coordinate of the touch (0..touch.xres)
event.tfinger.y - the y coordinate of the touch (0..touch.yres)
event.tfinger.pressure - the pressure of the touch (0..touch.pressureres)
SDL_FINGERMOTION:
Sent when a finger (or stylus) is moved on the touch device.
Fields:
Same as FINGERDOWN but with additional:
event.tfginer.dx - change in x coordinate during this motion event.
event.tfginer.dy - change in y coordinate during this motion event.
SDL_FINGERMOTION:
Sent when a finger (or stylus) is lifted from the touch device.
Fields:
Same as FINGERDOWN.
===========================================================================
Functions
===========================================================================
SDL provides the ability to access the underlying Touch and Finger structures.
These structures should _never_ be modified.
The following functions are included from SDL_Touch.h
To get a SDL_Touch device call SDL_GetTouch(touchId).
This returns an SDL_Touch*.
IMPORTANT: If the touch has been removed, or there is no touch with the given ID, SDL_GetTouch will return null. Be sure to check for this!
An SDL_Touch has the following fields:
>xres,yres,pressures:
The resolution at which x,y, and pressure values are reported. Currently these will always be equal to 2^15, but this may not always be the case.
>pressure_max, pressure_min, x_max, x_min, y_max, y_min
Which give, respectively, the maximum and minumum values that the touch digitizer can return for pressure, x coordiniate, and y coordinate AS REPORTED BY THE OPERATING SYSTEM.
On Mac/iPhone systems _max will always be 0, and _min will always be 1.
>native_xres,native_yres,native_pressureres:
The native resolution of the touch device AS REPORTED BY THE OPERATING SYSTEM.
On Mac/iPhone systems these will always be 1.
>num_fingers:
The number of fingers currently down on the device.
>fingers:
An array of pointers to the fingers which are on the device.
The most common reason to access a touch device is to normalize inputs. This would be accomplished by code like the following:
SDL_Touch* inTouch = SDL_GetTouch(event.tfinger.touchId);
if(inTouch == NULL) continue; //The touch has been removed
float x = ((float)event.tfinger.x)/inTouch->xres;
float y = ((float)event.tfinger.y)/inTouch->yres;
To get an SDL_Finger, call SDL_GetFinger(touch,fingerId), where touch is a pointer to an SDL_Touch device, and fingerId is the id of the requested finger.
This returns an SDL_Finger*, or null if the finger does not exist, or has been removed.
An SDL_Finger is guaranteed to be persistent for the duration of a touch, but it will be de-allocated as soon as the finger is removed. This occurs when the SDL_FINGERUP event is _added_ to the event queue, and thus _before_ the FINGERUP event is polled.
As a result, be very careful to check for null return values.
An SDL_Finger has the following fields:
>x,y,pressure:
The current coordinates of the touch.
>xdelta,ydelta:
The change in position resulting from the last finger motion.
>last_x, last_y, last_pressure:
The previous coordinates of the touch.

Simple DirectMedia Layer
(SDL)
Version 2.0
---
http://www.libsdl.org/
Simple DirectMedia Layer is a cross-platform development library designed
to provide low level access to audio, keyboard, mouse, joystick, and graphics
hardware via OpenGL and Direct3D. It is used by video playback software,
emulators, and popular games including Valve's award winning catalog
and many Humble Bundle games.
SDL officially supports Windows, Mac OS X, Linux, iOS, and Android.
Support for other platforms may be found in the source code.
SDL is written in C, works natively with C++, and there are bindings
available for several other languages, including C# and Python.
This library is distributed under the zlib license, which can be found
in the file "COPYING.txt".
The best way to learn how to use SDL is to check out the header files in
the "include" subdirectory and the programs in the "test" subdirectory.
The header files and test programs are well commented and always up to date.
More documentation and FAQs are available online at:
http://wiki.libsdl.org/
If you need help with the library, or just want to discuss SDL related
issues, you can join the developers mailing list:
http://www.libsdl.org/mailing-list.php
Enjoy!
Sam Lantinga (slouken@libsdl.org)

James Turk</A>
</H3>
<p>
You can either use the precompiled libraries from <A HREF="http://www.libsdl.org/download.php"> the SDL Download web site </A>, or you can build SDL yourself.
</p>
<H3>
Building SDL
</H3>
<P>
Go into the VisualC directory and double-click on the Visual Studio solution for your version of Visual Studio, e.g. <CODE>SDL_VS2008.sln</CODE> This should open up the IDE.
</P>
<P>
There are different solution files for the various
versions of the IDE. Please use the appropiate version
2008, 2010 or 2012; the 2010EE and 2012EE files
should be used with the "Express Edition" releases.
</P>
<P>
Build the <CODE>.dll</CODE> and <CODE>.lib</CODE> files.
</P>
<P>
This is done by right clicking on each project in turn (Projects are listed in
the Workspace panel in the FileView tab), and selecting "Build".
</P>
<P>
You may get a few warnings, but you should not get any errors. You do have to
have at least the DirectX 9 SDK installed, however. The latest
version of DirectX can be downloaded from <A HREF="http://www.microsoft.com">Microsoft</A>.
</P>
<P>
Later, we will refer to the following .lib and .dll files that have just been
generated:
</P>
<ul>
<li> SDL2.dll</li>
<li> SDL2.lib</li>
<li> SDL2main.lib</li>
</ul>
<P>
Search for these using the Windows Find (Windows-F) utility inside the VisualC directory.
</P>
<H3>
Creating a Project with SDL
</H3>
<P>
Create a project as a Win32 Application.
</P>
<P>
Create a C++ file for your project.
</P>
<P>
Set the C runtime to "Multi-threaded DLL" in the menu: <CODE>Project|Settings|C/C++
tab|Code Generation|Runtime Library </CODE>.
</P>
<P>
Add the SDL <CODE>include</CODE> directory to your list of includes in the
menu: <CODE>Project|Settings|C/C++ tab|Preprocessor|Additional include directories </CODE>
.
<br>
<STRONG><FONT color="#009900">VC7 Specific: Instead of doing this I find it easier to
add the include and library directories to the list that VC7 keeps. Do this by
selecting Tools|Options|Projects|VC++ Directories and under the "Show
Directories For:" dropbox select "Include Files", and click the "New Directory
Icon" and add the [SDLROOT]\include directory (e.g. If you installed to
c:\SDL\ add c:\SDL\include).&nbsp;Proceed to&nbsp;change the
dropbox selection to "Library Files" and add [SDLROOT]\lib.</FONT></STRONG>
</P>
<P>
The "include directory" I am referring to is the <CODE>include</CODE> folder
within the main SDL directory (the one that this HTML file located within).
</P>
<P>
Now we're going to use the files that we had created earlier in the Build SDL
step.
</P>
<P>
Copy the following files into your Project directory:
</P>
<ul>
<li> SDL2.dll</li>
</ul>

Add the following files to your project (It is not necessary to copy them to
your project directory):
</P>
<ul>
<li> SDL2.lib </li>
<li> SDL2main.lib</li>
</ul>
<P>
(To add them to your project, right click on your project, and select "Add
files to project")
</P>
<P><STRONG><FONT color="#009900">Instead of adding the files to your project it is more
desireable to add them to the linker options: Project|Properties|Linker|Command

configuration (e.g. Release,Debug).</FONT></STRONG></P>

SDL 101, First Day of Class
</H3>
<P>
Now create the basic body of your project. The body of your program should take
the following form: <CODE>
<PRE>
#include "SDL.h"
int main( int argc, char* argv[] )
{
// Body of the program goes here.
return 0;
}
</PRE>
</CODE>
<P></P>
<H3>
That's it!
</H3>
<P>
I hope that this document has helped you get through the most difficult part of
using the SDL: installing it. Suggestions for improvements to this document
should be sent to the writers of this document.

Using SDL with Microsoft Visual C++
</H1>

<p>
You can either use the precompiled libraries from <A HREF="http://www.libsdl.org/download.php"> the SDL Download web site </A>, or you can build SDL yourself.
</p>
<H3>
Building SDL
</H3>
<P>
Go into the VisualC directory and double-click on the Visual Studio solution for your version of Visual Studio, e.g. <CODE>SDL_VS2008.sln</CODE> This should open up the IDE.
</P>
<P>
There are different solution files for the various
versions of the IDE. Please use the appropiate version
2008, 2010 or 2012; the 2010EE and 2012EE files
should be used with the "Express Edition" releases.
</P>
<P>
Build the <CODE>.dll</CODE> and <CODE>.lib</CODE> files.
</P>
<P>
This is done by right clicking on each project in turn (Projects are listed in
the Workspace panel in the FileView tab), and selecting "Build".
</P>
<P>
You may get a few warnings, but you should not get any errors. You do have to
have at least the DirectX 9 SDK installed, however. The latest
version of DirectX can be downloaded from <A HREF="http://www.microsoft.com">Microsoft</A>.
</P>
<P>
Later, we will refer to the following .lib and .dll files that have just been
generated:
</P>
<ul>
<li> SDL2.dll</li>
<li> SDL2.lib</li>
<li> SDL2main.lib</li>
</ul>
<P>
Search for these using the Windows Find (Windows-F) utility inside the VisualC directory.
</P>
<H3>
Creating a Project with SDL
</H3>
<P>
Create a project as a Win32 Application.
</P>
<P>
Create a C++ file for your project.
</P>
<P>
Set the C runtime to "Multi-threaded DLL" in the menu: <CODE>Project|Settings|C/C++
tab|Code Generation|Runtime Library </CODE>.
</P>
<P>
Add the SDL <CODE>include</CODE> directory to your list of includes in the
menu: <CODE>Project|Settings|C/C++ tab|Preprocessor|Additional include directories </CODE>
.
<br>
<STRONG><FONT color="#009900">VC7 Specific: Instead of doing this I find it easier to
add the include and library directories to the list that VC7 keeps. Do this by
selecting Tools|Options|Projects|VC++ Directories and under the "Show
Directories For:" dropbox select "Include Files", and click the "New Directory
Icon" and add the [SDLROOT]\include directory (e.g. If you installed to
c:\SDL\ add c:\SDL\include).&nbsp;Proceed to&nbsp;change the
dropbox selection to "Library Files" and add [SDLROOT]\lib.</FONT></STRONG>
</P>
<P>
The "include directory" I am referring to is the <CODE>include</CODE> folder
within the main SDL directory (the one that this HTML file located within).
</P>
<P>
Now we're going to use the files that we had created earlier in the Build SDL
step.
</P>
<P>
Copy the following files into your Project directory:
</P>
<ul>
<li> SDL2.dll</li>
</ul>
<P>
Add the following files to your project (It is not necessary to copy them to
your project directory):
</P>
<ul>
<li> SDL2.lib </li>
<li> SDL2main.lib</li>
</ul>
<P>
(To add them to your project, right click on your project, and select "Add
files to project")
</P>
<P><STRONG><FONT color="#009900">Instead of adding the files to your project it is more
desireable to add them to the linker options: Project|Properties|Linker|Command
Line and type the names of the libraries to link with in the "Additional
Options:" box.&nbsp; Note: This must be done&nbsp;for&nbsp;each&nbsp;build
configuration (e.g. Release,Debug).</FONT></STRONG></P>
<H3>
SDL 101, First Day of Class
</H3>
<P>
Now create the basic body of your project. The body of your program should take
the following form: <CODE>
<PRE>
#include "SDL.h"
int main( int argc, char* argv[] )
{
// Body of the program goes here.
return 0;
}
</PRE>
</CODE>
<P></P>
<H3>
That's it!
</H3>
<P>
I hope that this document has helped you get through the most difficult part of
using the SDL: installing it. Suggestions for improvements to this document
should be sent to the writers of this document.
</P>

* \section intro_sec Introduction
*
* This is the Simple DirectMedia Layer, a general API that provides low
* level access to audio, keyboard, mouse, joystick, 3D hardware via OpenGL,
* and 2D framebuffer across multiple platforms.
*
* SDL is written in C, but works with C++ natively, and has bindings to
* several other languages, including Ada, C#, Eiffel, Erlang, Euphoria,
* Guile, Haskell, Java, Lisp, Lua, ML, Objective C, Pascal, Perl, PHP,
* Pike, Pliant, Python, Ruby, and Smalltalk.
*
* This library is distributed under the zlib license, which can be
* found in the file "COPYING". This license allows you to use SDL
* freely for any purpose as long as you retain the copyright notice.
*
* The best way to learn how to use SDL is to check out the header files in
* the "include" subdirectory and the programs in the "test" subdirectory.
* The header files and test programs are well commented and always up to date.
* More documentation and FAQs are available online at:
* http://wiki.libsdl.org/
*
* If you need help with the library, or just want to discuss SDL related
* issues, you can join the developers mailing list:
* http://www.libsdl.org/mailing-list.php
*
* Enjoy!

* IMPORTANT:
* If you are not an expert in concurrent lockless programming, you should
* only be using the atomic lock and reference counting functions in this
* file. In all other cases you should be protecting your data structures
* with full mutexes.
*
* The list of "safe" functions to use are:
* SDL_AtomicLock()
* SDL_AtomicUnlock()
* SDL_AtomicIncRef()
* SDL_AtomicDecRef()
*
* Seriously, here be dragons!
* ^^^^^^^^^^^^^^^^^^^^^^^^^^^
*
* You can find out a little more about lockless programming and the
* subtle issues that can arise here:
* http://msdn.microsoft.com/en-us/library/ee418650%28v=vs.85%29.aspx
*
* There's also lots of good information here:
* http://www.1024cores.net/home/lock-free-algorithms
* http://preshing.com/
*
* These operations may or may not actually be implemented using
* processor specific atomic operations. When possible they are
* implemented as true processor specific atomic operations. When that
* is not possible the are implemented using locks that *do* use the
* available atomic operations.
*
