Summary of the bug:

Cross-compiling master fails for Android arm64 architecture.

How to reproduce using Android NDK r18b:

cd $ANDROID_NDK_ROOT/build/tools
./make_standalone_toolchain.py --arch arm64 --api 21 --stl libc++ --install-dir $ANDROID_NDK_ROOT/toolchains/test-arm64

./configure --cross-prefix=$ANDROID_NDK_ROOT/toolchains/test-arm64/bin/aarch64-linux-android- --sysroot=$ANDROID_NDK_ROOT/toolchains/test-arm64/sysroot --arch=arm64 --target-os=android

make -j4

make fails with these errors.

  • Component changed from build system to avcodec
  • Keywords changed from android,arm64 to android arm64
  • Reproduced by developer set

Either use a patch by Martin Storsjö or --extra-cflags=-fno-integrated-as:

Thanks, --extra-cflags=-fno-integrated-as fixed errors for me.

I tried to build with patch too, but it failed with these.
