I managed to build gambit for arm but now I have a problem with compling C code using the android provided tool-chain
export NDK=$ANDROID_SDK_ROOT/ndk-bundle export TOOLCHAIN=$NDK/toolchains/llvm/prebuilt/linux-x86_64 export TARGET=aarch64-linux-android export API=30 export AR=$TOOLCHAIN/bin/llvm-ar export CC=$TOOLCHAIN/bin/$TARGET$API-clang export AS=$CC export CXX=$TOOLCHAIN/bin/$TARGET$API-clang++ export LD=$TOOLCHAIN/bin/ld export RANLIB=$TOOLCHAIN/bin/llvm-ranlib export STRIP=$TOOLCHAIN/bin/llvm-strip
./configure --prefix=/home/sto/gambit-arm --build=x86_64 --host=$TARGET
the build-ambit-android.sh as pointed out by Francoi Magan is obsolete https://developer.android.com/ndk/guides/standalone_toolchain
this is how I tried to compile hello.c
sto@gambit:~/workspace/hello$ clang --target=aarch64-linux-android-30 hello.c hello_.c -I$GAMBIT/include $GAMBIT/lib/libgambit.a --sysroot=$TOOLCHAIN/llvm/prebuilt/linux-x86_64/sysroot/ In file included from hello.c:40: /home/sto/gambit/include/gambit.h:866:10: fatal error: 'wchar.h' file not found #include <wchar.h> ^~~~~~~~~ 1 error generated.

sto@gambit:~/android$ find . -name wchar.h ./ndk-bundle/toolchains/llvm/prebuilt/linux-x86_64/sysroot/usr/include/wchar.h ./ndk-bundle/toolchains/llvm/prebuilt/linux-x86_64/sysroot/usr/include/c++/v1/wchar.h ./ndk-bundle/toolchains/llvm/prebuilt/linux-x86_64/sysroot/usr/include/c++/v1/support/solaris/wchar.h ./ndk-bundle/toolchains/llvm/prebuilt/linux-x86_64/sysroot/usr/local/include/wchar.h ./ndk-bundle/sources/cxx-stl/llvm-libc++/include/wchar.h ./ndk-bundle/sources/cxx-stl/llvm-libc++/include/support/solaris/wchar.h ./ndk-bundle/sources/android/support/include/wchar.h

clang --target=aarch64-linux-android-30 hello.c hello_.c -I$GAMBIT/include $GAMBIT/lib/libgambit.a --sysroot=$TOOLCHAIN/llvm/prebuilt/linux-x86_64/sysroot/ -I$TOOLCHAIN/sysroot/usr/include In file included from hello.c:40: /home/sto/gambit/include/gambit.h:866:10: fatal error: 'wchar.h' file not found #include <wchar.h> ^~~~~~~~~ 1 error generated. In file included from hello_.c:9499: /home/sto/gambit/include/gambit.h:866:10: fatal error: 'wchar.h' file not found
I am not sure how to fix this. I've explicitly added -I$TOOLCHAIN/sysroot/usr/include which is where wchar.h is located but its still complaining that it cannot find that file

Yes and there a script for that in `misc` folder named `build-ambit-android.sh`. Didn't try it yet, Francois

Thanks Alexander! that was helpful.

This error probably means I need to build libgambit.a for ARM.
probably yes.
