使用zeranoe的自动化脚本mingw-w64-build-3.6.4在ubutun14.04_64bit上交叉编译ffmpeg 2.5
编译期间,碰到的两个大问题,是环境变量设置问题.
先列出执行脚本是碰到的两个问题,后面给出解决方法并记录执行的命令步骤.
问题1: 编译binutils 2.5出错

-------------------------------
碰到上面两个问题,请尝试一下以下方法,个人亲试:
unset LIBRARY_PATH CPATH C_INCLUDE_PATH PKG_CONFIG_PATH CPLUS_INCLUDE_PATH INCLUDE
如果在/etc/profile 或者 ~/.bashrc中设置了ccache的话,也暂时去掉ccache的设置.
【编译32bit】 注意 一些路径要换成自己本机的路径
准备工作:
脚本获取:wget http://zeranoe.com/scripts/mingw_w64_build/mingw-w64-build-3.6.4 ，然后修改权限
ubuntu14.04情况下,执行:sudo apt-get install pax cvs flex bison texinfo
执行:bash ./mingw-w64-build-3.6.4 --build-type=multi --default-configure --disable-shared --enable-gendef
(1)ln -s "/usr/bin/pkg-config" /home/shakin/work/build_ffmpeg_for_windows/mingw-w64-i686/bin/i686-w64-mingw32-pkg-config
(2)编译 x264
./configure --enable-static --enable-win32thread --host=i686-w64-mingw32 --prefix=/home/shakin/work/build_ffmpeg_for_windows/dist/modules --cross-prefix=i686-w64-mingw32-
(3)编译libfdk_aac
./configure --host=i686-w64-mingw32 --prefix=/home/shakin/work/build_ffmpeg_for_windows/dist/modules --enable-static --disable-shared
其他的外插件略,需要安装的官网也有详细步骤.
(4)编译ffmpeg
./configure --disable-static --enable-shared --enable-version3 --enable-gpl --enable-nonfree --disable-pthreads --enable-w32threads --enable-runtime-cpudetect --enable-memalign-hack --enable-libfdk-aac --enable-libx264 --enable-zlib --enable-cross-compile --target-os=mingw32 --arch=x86 --prefix=/home/shakin/work/build_ffmpeg_for_windows/dist/modules/ffmpeg --cross-prefix=i686-w64-mingw32- --extra-cflags="-I/home/shakin/work/build_ffmpeg_for_windows/dist/modules/include" --extra-ldflags="-L/home/shakin/work/build_ffmpeg_for_windows/dist/modules/lib"
编译的 exe和 dll文件,就在/home/shakin/work/build_ffmpeg_for_windows/dist/modules/ffmpeg 路径下,另外,编译成64位版时,libx264,libfdk_aac等也要相应的变成64bit,
编译 x264
./configure --enable-static --enable-win32thread --host=x86_64-w64-mingw32 --prefix=/home/shakin/work/build_ffmpeg_for_windows/dist/modules --cross-prefix=x86_64-w64-mingw32-
编译libfdk_aac
./configure --host=x86_64-w64-mingw32 --prefix=/home/shakin/work/build_ffmpeg_for_windows/dist/modules --enable-static --disable-shared
编译ffmpeg
./configure --disable-static --enable-shared --enable-version3 --enable-gpl --enable-nonfree --disable-pthreads --enable-w32threads --enable-runtime-cpudetect --enable-memalign-hack --enable-libfdk-aac --enable-libx264 --enable-zlib --enable-cross-compile --target-os=mingw32 --arch=x86 --prefix=/home/shakin/work/build_ffmpeg_for_windows/dist/modules/ffmpeg --cross-prefix=x86_64-w64-mingw32- --extra-cflags="-I/home/shakin/work/build_ffmpeg_for_windows/dist/modules/include" --extra-ldflags="-L/home/shakin/work/build_ffmpeg_for_windows/dist/modules/lib"
