hi@hi:~/3tb_volume/ffmpeg/ffmpeg-4.1$ which ndk-build

1.使用Android Studio默认下载的ndk编译ffmpeg4.1
export NDK=/home/hi/Android/Sdk/ndk-bundle

提示错误如下
hi@hi:~/3tb_volume/ffmpeg/ffmpeg-4.1$ ./build2.sh
/home/hi/Android/Sdk/ndk-bundle/toolchains/arm-linux-androideabi-4.9/prebuilt/linux-x86_64/bin/arm-linux-androideabi-gcc is unable to create an executable file.
C compiler test failed.

If you think configure made a mistake, make sure you are using the latest
version from Git. If the latest version fails, report the problem to the
[e-mail] mailing list or IRC #ffmpeg on irc.freenode.net.
Include the log file "ffbuild/config.log" produced by configure as this will help
solve the problem.

注：使用android-ndk-r16b也报同样的错误，也就是说新版本会报这个错误

2.ndk替换为android-ndk-r10e版本和android-ndk-r14b
export NDK=/home/hi/bin/android-ndk-r10e
不再报错：
hi@hi:~/3tb_volume/ffmpeg/ffmpeg-4.1$ ./build2.sh
install prefix ../fflib
source path .

3.执行make，还是会报错：
CC libavformat/udp.o
libavformat/udp.c: In function 'udp_set_multicast_sources':
libavformat/udp.c:290:28: error: request for member 's_addr' in something not a structure or union
mreqs.imr_multiaddr.s_addr = ((struct sockaddr_in *)addr)->sin_addr.s_addr;
^
compilation terminated due to -Wfatal-errors.
make: *** [libavformat/udp.o] 错误 1

有大神知道怎么解决吗？

楼主解决了吗？ 同样问题ndk14 windows64位 msys2编译的，也是卡在 CC libavformat/udp.o

[baobrother阿振]

附我的.sh make clean export NDK=D:/android-ndk-r14b export PLATFORM=$NDK/platforms/android-14/arch-arm export TOOLCHAIN=$NDK/toolchains/arm-linux-androideabi-4.9/prebuilt/windows-x86_64 export PREFIX=../androidfflib export ADDI_CFLAGS="-marm" export TMPDIR=D:/ffmpeg-4.0.3/temp build_one(){ ./configure --target-os=linux \ --extra-libs=-lgcc \ --prefix=$PREFIX --arch=arm \ --enable-cross-compile \ --disable-doc \ --enable-shared \ --disable-static \ --disable-asm \ --disable-symver \ --enable-gpl \ --disable-ffmpeg \ --disable-ffplay \ --disable-ffprobe \ --cc=$TOOLCHAIN/bin/arm-linux-androideabi-gcc \ --cross-prefix=$TOOLCHAIN/bin/arm-linux-androideabi- \ --sysroot=$PLATFORM \ --extra-cflags="-Os -fpic $ADDI_CFLAGS" \ --extra-ldflags="$ADDI_CFLAGS" \ $ADDITIONAL_CONFIGURE_FLAG } build_one

[baobrother阿振]

大神顺便帮我看一下我的.sh有没有什么问题

换了build编译脚本，可以编译通过了，参考： ubuntu14.04系统Android NDK编译ffmpeg遇到的问题
