我将尝试在OpenH264中为不同的CPU架构构建.so文件。
OpenH264的README.md建议:
add "ARCH=mips" or "ARCH=x86". To build for the older armeabi ABI (which has
armv5te as baseline), add "APP_ABI=armeabi" (ARCH=arm is implicit).
我执行了以下命令:
针对x86架构:
make os=android NDKROOT=/home/neosoft/android-ndk-r10d/ ARCH=x86 TARGET=android-12
我得到的类似于
这样的东西
。/usr/bin/ld: cannot find crti.o: No such file or directory

collect2: error: ld returned 1 exit status
make: *** [libopenh264.so] Error 1
当我尝试使用armeabi编译时
make os=android NDKROOT=/home/neosoft/android-ndk-r10d/ ARCH=armeabi TARGET=android-12
我理解了
cc -O3 -DHAVE_NEON -Wall -fno-strict-aliasing -fPIC -DLINUX -MMD -MP -Icodec/common/arm/ -march=armv7-a -mfpu=neon -Icodec/api/svc -Icodec/common/inc -c -o codec/common/arm/copy_mb_neon.o codec/common/arm/copy_mb_neon.S
cc: error: unrecognized command line option ‘-mfpu=neon’
make: *** [codec/common/arm/copy_mb_neon.o] Error 1
有人能告诉我如何为不同的CPU架构编译此库吗?
