# Google Android makefile for curl and libcurl
|
|
#
|
|
# Place the curl source (including this makefile) into external/curl/ in the
|
|
# Android source tree. Then build them with 'make curl' or just 'make libcurl'
|
|
# from the Android root. Tested with Android 1.5 and 2.1
|
|
#
|
|
# Note: you must first create a curl_config.h file by running configure in the
|
|
# Android environment. The only way I've found to do this is tricky. Perform a
|
|
# normal Android build with libcurl in the source tree, providing the target
|
|
# "showcommands" to make. The build will eventually fail (because curl_config.h
|
|
# doesn't exist yet), but the compiler commands used to build curl will be
|
|
# shown. Now, from the external/curl/ directory, run curl's normal configure
|
|
# command with flags that match what Android itself uses. This will mean
|
|
# putting the compiler directory into the PATH, putting the -I, -isystem and
|
|
# -D options into CPPFLAGS, putting the -W, -m, -f, -O and -nostdlib options
|
|
# into CFLAGS, and putting the -Wl, -L and -l options into LIBS, along with the
|
|
# path to the files libgcc.a, crtbegin_dynamic.o, and ccrtend_android.o.
|
|
# Remember that the paths must be absolute since you will not be running
|
|
# configure from the same directory as the Android make. The normal
|
|
# cross-compiler options must also be set. Note that the -c, -o, -MD and
|
|
# similar flags must not be set.
|
|
#
|
|
# To see all the LIBS options, you'll need to do the "showcommands" trick on an
|
|
# executable that's already buildable and watch what flags Android uses to link
|
|
# it (dhcpcd is a good choice to watch). You'll also want to add -L options to
|
|
# LIBS that point to the out/.../obj/lib/ and out/.../obj/system/lib/
|
|
# directories so that additional libraries can be found and used by curl.
|
|
#
|
|
# The end result will be a configure command that looks something like this
|
|
# (the environment variable A is set to the Android root path which makes the
|
|
# command shorter):
|
|
#
|
|
# A=`realpath ../..` && \
|
|
# PATH="$A/prebuilt/linux-x86/toolchain/arm-eabi-X/bin:$PATH" \
|
|
# ./configure --host=arm-linux CC=arm-eabi-gcc \
|
|
# CPPFLAGS="-I $A/system/core/include ..." \
|
|
# CFLAGS="-nostdlib -fno-exceptions -Wno-multichar ..." \
|
|
# LIBS="$A/prebuilt/linux-x86/toolchain/arm-eabi-X/lib/gcc/arm-eabi/X\
|
|
# /interwork/libgcc.a ..."
|
|
#
|
|
# Finally, copy the file COPYING to NOTICE so that the curl license gets put
|
|
# into the right place (but see the note about this below).
