【问题描述】:
我正在尝试为 OpenH264 中的不同 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).
所以我触发了以下命令
对于 x86
make os=android NDKROOT=/home/neosoft/android-ndk-r10d/ ARCH=x86 TARGET=android-12
我得到了类似的东西
/usr/bin/ld: cannot find crti.o: No such file or directory
/usr/bin/ld: cannot find -lpthread
/usr/bin/ld: skipping incompatible /usr/lib/gcc/x86_64-linux-gnu/4.8/libstdc++.so when searching for -lstdc++
/usr/bin/ld: skipping incompatible /usr/lib/gcc/x86_64-linux-gnu/4.8/libstdc++.a when searching for -lstdc++
/usr/bin/ld: cannot find -lstdc++
/usr/bin/ld: cannot find -lm
/usr/bin/ld: skipping incompatible /usr/lib/gcc/x86_64-linux-gnu/4.8/libgcc_s.so when searching for -lgcc_s
/usr/bin/ld: cannot find -lgcc_s
/usr/bin/ld: cannot find -lc
/usr/bin/ld: skipping incompatible /usr/lib/gcc/x86_64-linux-gnu/4.8/libgcc_s.so when searching for -lgcc_s
/usr/bin/ld: cannot find -lgcc_s
/usr/bin/ld: cannot find crtn.o: No such file or directory
collect2: error: ld returned 1 exit status
make: *** [libopenh264.so] Error 1
当我尝试用 armeabi 构建它时
make os=android NDKROOT=/home/neosoft/android-ndk-r10d/ ARCH=armeabi TARGET=android-12
我明白了
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
谁能告诉我如何为不同的 cpu 架构编译这个库。
