The changelog is no longer maintained by hand. It made sense to have a single
timeline when we were using CVS, but modern revision control tools make this
redundant, at best.
If you want a list of changes, updated in real time, just point your web

The latest PhysicsFS information and releases can be found at:
http://icculus.org/physfs/
Building is (ahem) very easy.
ALL PLATFORMS:
Please understand your rights and mine: read the text file LICENSE.txt in the
root of the source tree. If you can't abide by it, delete this source tree
now. The license is extremely liberal, even to closed-source, commercial
applications.
If you've got Doxygen (http://www.doxygen.org/) installed, you can run it
without any command line arguments in the root of the source tree to generate
the API reference (or build the "docs" target from your build system). This
is optional. You can browse the API docs online here:
http://icculus.org/physfs/docs/
UNIX:
You will need CMake (http://www.cmake.org/) 2.4 or later installed.
Make a directory, wherever you like. This will be your build directory.
Chdir to your build directory. Run "cmake /where/i/unpacked/physfs" to
generate Makefiles. You can then run "ccmake ." and customize the build,
but the defaults are probably okay. You can have CMake generate KDevelop
project files if you prefer these.
Run "make". PhysicsFS will now build.
As root, run "make install".
If you get sick of the library, run "xargs rm < install_manifest.txt" as root
and it will remove all traces of the library from the system paths.
Once you are satisfied, you can delete the build directory.
Primary Unix development is done with GNU/Linux, but PhysicsFS is known to
work out of the box with several flavors of Unix. It it doesn't work, patches
to get it running can be sent to icculus@icculus.org.
BeOS, Zeta, and Haiku:
Use the "Unix" instructions, above. The CMake port to BeOS is fairly new at
the time of this writing, but it works. You can get a build of CMake from
bebits.com or build it yourself from source from cmake.org.
Windows:
If building with Cygwin, mingw32, MSYS, or something else that uses the GNU
toolchain, follow the Unix instructions, above.
If you want to use Visual Studio, nmake, or the Platform SDK, you will need
CMake (http://www.cmake.org/) 2.4 or later installed. Point CMake at the
CMakeLists.txt file in the root of the source directory and hit the
"Configure" button. After telling it what type of compiler you are targeting
(Borland, Visual Studio, etc), CMake will process for while and then give you
a list of options you can change (what archivers you want to support, etc).
If you aren't sure, the defaults are probably fine. Hit the "Configure"
button again, then "OK" once configuration has completed with options that
match your liking. Now project files for your favorite programming
environment will be generated for you in the directory you specified.
Go there and use them to build PhysicsFS.
PhysicsFS will only link directly against system libraries that have existed
since Windows 95 and Windows NT 3.51. If there's a newer API we want to use,
we try to dynamically load it at runtime and fallback to a reasonable
behaviour when we can't find it...this is used for Unicode support and
locating user-specific directories, etc.
PhysicsFS has not been tested on 64-bit Windows, but probably works. There is
no 16-bit Windows support at all. Reports of success and problems can go to
Ryan at icculus@icculus.org ...
If someone is willing to maintain prebuilt PhysicsFS DLLs, I'd like to hear
from you; send an email to icculus@icculus.org ...
PocketPC/WindowsCE:
Code exists for PocketPC support, and there are shipping titles that used
PhysicsFS 1.0 on PocketPC...but it isn't tested in 2.0, and is probably
broken with the new build system. Please send patches.
MAC OS 8/9:
Classic Mac OS support has been dropped in PhysicsFS 2.0. Apple hasn't updated
pre-OSX versions in more than a decade at this point, none of the hardware
they've shipped will boot it for almost as many years, and finding
developer tools for it is becoming almost impossible. As the switch to Intel
hardware has removed the "Classic" emulation environment, it was time to
remove support from PhysicsFS. That being said, the PhysicsFS 1.0 branch can
still target back to Mac OS 8.5, so you can use that if you need support for
this legacy OS. We still very much support Mac OS X, though: see below.
MAC OS X:
You will need CMake (http://www.cmake.org/) 2.4 or later installed.
You can either generate a Unix makefile with CMake, or generate an Xcode
project, whichever makes you more comfortable.
PowerPC and Intel Macs should both be supported.
If someone is willing to maintain prebuilt PhysicsFS Shared Libraries for
Mac OS X, I'd like to hear from you; send an email to icculus@icculus.org.
OS/2:
You need Innotek GCC and libc installed (or kLIBC). I tried this on a stock
Warp 4 install, no fixpaks. You need to install link386.exe (Selective
Install, "link object modules" option). Once klibc and GCC are installed
correctly, unpack the source to PhysicsFS and run the script
file "makeos2.cmd". I know this isn't ideal, but I wanted to have this build
without users having to hunt down a "make" program.
Someone please port CMake to OS/2. Ideally I'd like to be able to target
Innotek GCC and OpenWatcom with CMake.
If someone is willing to maintain prebuilt PhysicsFS Shared Libraries for
OS/2, I'd like to hear from you; send an email to icculus@icculus.org.
OTHER PLATFORMS:
Many Unix-like platforms might "just work" with CMake. Some of these platforms
are known to have worked at one time, but have not been heavily tested, if
tested at all. PhysicsFS is, as far as we know, 64-bit and byteorder clean,
and is known to compile on several compilers across many platforms. To
implement a new platform or archiver, please read the heavily-commented
physfs_internal.h and look in the platform/ and archiver/ directories for
examples.

Stuff that needs to be done and wishlist:
These are in no particular order.
Some might be dupes, some might be done already.
UNICODE:
- OS/2: Codepages. No full Unicode in the filesystem, but we can probably make
a conversion effort.
Stuff:
- Other archivers: perhaps tar(.gz|.bz2), RPM, ARJ, etc. These are less
important, since streaming archives aren't of much value to games (which
is why zipfiles are king: random access), but it could have uses for, say,
an installer/updater.
- Reduce malloc() pressure all over the place. We fragment memory like mad.
- profile string list interpolation.
- We have two different ways to find dir entries in zip.c.
- Do symlinks in zip archiver work when they point to dirs?
- Enable more warnings?
- Use __cdecl in physfs.h?
- Look for FIXMEs (many marked with "!!!" in comments).
- Find some way to relax or remove the security model for external tools.
- OSX shouldn't use ~/.app for userdir.
- fscanf and fprintf support in extras dir.
- Why do we call it openArchive and dirClose?
- Sanity check byte order at runtime.
- Memory locking?
- Find a better name than dvoid and fvoid.
- Can windows.c and pocketpc.c get merged?
- There's so much cut-and-paste between archivers...can this be reduced?
- General code audit.
- Multiple write dirs with mount points?
- Deprecate PHYSFS_setSaneConfig and move it to extras?
- Why is physfsrwops.c cut-and-pasted into the ruby bindings?
- Replace code from SDL...
- Should file enumeration return an error or set error state?
- Need "getmountpoint" command in test_physfs.c ...
- Look for calloc() calls that aren't going through the allocation hooks.
- Write up a simple HOWTO on embedding physicsfs in another project.
- Archivers need abstracted i/o to read from memory or files (archives in archives?)
- Probably other stuff. Requests and recommendations are welcome.

/*
* GRP support routines for PhysicsFS.
*
* This driver handles BUILD engine archives ("groupfiles"). This format
* (but not this driver) was put together by Ken Silverman.
*
* The format is simple enough. In Ken's words:
*
* What's the .GRP file format?
*
* The ".grp" file format is just a collection of a lot of files stored
* into 1 big one. I tried to make the format as simple as possible: The
* first 12 bytes contains my name, "KenSilverman". The next 4 bytes is
* the number of files that were compacted into the group file. Then for
* each file, there is a 16 byte structure, where the first 12 bytes are
* the filename, and the last 4 bytes are the file's size. The rest of
* the group file is just the raw data packed one after the other in the
* same order as the list of files.
*
* (That info is from http://www.advsys.net/ken/build.htm ...)

/*
* HOG support routines for PhysicsFS.
*
* This driver handles Descent I/II HOG archives.
*
* The format is very simple:
*
* The file always starts with the 3-byte signature "DHF" (Descent
* HOG file). After that the files of a HOG are just attached after
* another, divided by a 17 bytes header, which specifies the name
* and length (in bytes) of the forthcoming file! So you just read
* the header with its information of how big the following file is,
* and then skip exact that number of bytes to get to the next file
* in that HOG.
*
* char sig[3] = {'D', 'H', 'F'}; // "DHF"=Descent HOG File
*
* struct {
* char file_name[13]; // Filename, padded to 13 bytes with 0s
* int file_size; // filesize in bytes
* char data[file_size]; // The file data
* } FILE_STRUCT; // Repeated until the end of the file.
*
* (That info is from http://www.descent2.com/ddn/specs/hog/)
*
* Please see the file LICENSE.txt in the source's root directory.
*
* This file written by Bradley Bell.
* Based on grp.c by Ryan C. Gordon.

/*
* WAD support routines for PhysicsFS.
*
* This driver handles DOOM engine archives ("wads").
* This format (but not this driver) was designed by id Software for use
* with the DOOM engine.
* The specs of the format are from the unofficial doom specs v1.666
* found here: http://www.gamers.org/dhs/helpdocs/dmsp1666.html
* The format of the archive: (from the specs)
*
* A WAD file has three parts:
* (1) a twelve-byte header
* (2) one or more "lumps"
* (3) a directory or "info table" that contains the names, offsets, and
* sizes of all the lumps in the WAD
*
* The header consists of three four-byte parts:
* (a) an ASCII string which must be either "IWAD" or "PWAD"
* (b) a 4-byte (long) integer which is the number of lumps in the wad
* (c) a long integer which is the file offset to the start of
* the directory
*
* The directory has one 16-byte entry for every lump. Each entry consists
* of three parts:
*
* (a) a long integer, the file offset to the start of the lump
* (b) a long integer, the size of the lump in bytes
* (c) an 8-byte ASCII string, the name of the lump, padded with zeros.
* For example, the "DEMO1" entry in hexadecimal would be
* (44 45 4D 4F 31 00 00 00)
*
* Note that there is no way to tell if an opened WAD archive is a
* IWAD or PWAD with this archiver.
* I couldn't think of a way to provide that information, without being too
* hacky.
* I don't think it's really that important though.
*
*
* Please see the file LICENSE.txt in the source's root directory.
*
* This file written by Travis Wells, based on the GRP archiver by
* Ryan C. Gordon.
