Building libsdl with Android standalone toolchain

Hi,

Can anyone please help me understand how to build libsdl using the
Android NDK’s standalone toolchain? I can’t use the standard ndk-build
as I have to integrate with an existing build system.

I know I probably have to put the path and name of the cross-compiler in
my PATH and CC environment variables, respectively, but I assume there
is a bunch of other things that need to be done - e.g. SSE and 3DNow
probably need to be disabled (the target architecture is ARM) etc.

Thanks,

Anders Feder

To complete my previous answer as the email went out before intended (it
happens!)…don’t use the last line (env[‘MAKE’]), and try running
configure with:

./configure --host=arm-eabi --build=i686-pc-linux-gnu
–with-sysroot=[LOCATION OF THE NDK]/platforms/android-5/arch-arm

Let us know if it works!–

I think its possible to do what you want. I compile SDL_ttf this way and it
works fine. My env variables are: (this is copy pasted from a Python script
so you might have to adjust this if you want to use BASH or something else)

env[‘PATH’] =
"%s/toolchains/arm-linux-androideabi-4.4.3/prebuilt/linux-x86/bin/:%s:%s/tools:/usr/local/bin:/usr/bin:/bin:%s"
% (ANDROID_NDK, ANDROID_NDK, ANDROID_SDK, ‘’) #env[‘PATH’])
env[‘ARCH’] = "armeabi"
env[‘SDK’] = ANDROID_SDK

#env['ARCH'] = "armeabi-v7a"
env['CFLAGS'] ="-DANDROID -mandroid -fomit-frame-pointer --sysroot

%s/platforms/android-5/arch-arm" % (ANDROID_NDK)
if env[‘ARCH’] == “armeabi-v7a”:
env[‘CFLAGS’]+=" -march=armv7-a -mfloat-abi=softfp -mfpu=vfp -mthumb"
env[‘CXXFLAGS’] = env[‘CFLAGS’]
env[‘CC’] = ‘arm-linux-androideabi-gcc %s’ % (env[‘CFLAGS’],)
env[‘CXX’] = ‘arm-linux-androideabi-g++ %s’ % (env[‘CXXFLAGS’],)
env[‘AR’] = "arm-linux-androideabi-ar"
env[‘RANLIB’] = "arm-linux-androideabi-ranlib"
env[‘STRIP’] = "arm-linux-androideabi-strip --strip-unneeded"
env[‘MAKE’] = ‘make -k -j4 HOSTPYTHON=%s HOSTPGEN=%s
CROSS_COMPILE=arm-eabi- CROSS_COMPILE_TARGET=yes’ % (HOSTPYTHON, HOSTPGEN)–

Thanks a lot. It compiled fine, except I had to configure with
–host=arm-eabi-linux and --disable-joystick.
