系统信息:Ubuntu Release 10.04
主机编译器版本:
liwei@liwei:~$ gcc -v
Using built-in specs.
Target: i486-linux-gnu
… … … …
gcc version 4.4.3 (Ubuntu 4.4.3-4ubuntu5)
交叉编译器版本:
liwei@liwei:~$ arm-linux-gcc -v
Using built-in specs.
Target: arm-linux-uclibc
… … … …
gcc version 4.2.1
$ ./configure --arch=arm --target-os=linux --cc=arm-linux-gcc --enable-cross-compile --enable-shared --disable-network --disable-armv6 --disable-armv6t2 --disable-ffmpeg --disable-ffplay --disable-ffserver --enable-avfilter --enable-gpl --enable-swscale --enable-postproc --enable-gpl --enable-pthreads
出现如下问题:
Must specify target arch and OS when cross-compiling
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
ffmpeg-user@ffmpeg.org mailing list or IRC #ffmpeg on irc.freenode.net.
Include the log file "config.log" produced by configure as this will help
solving the problem.
通过./configure –help找到相关配置选项,传递linux给此选项,配置通过
2.拷贝目标文件:
拷贝如下头文件到/home/liwei/ffmpeg_install/include(实际为安装解码库时安装到系统目录下的头文件)
/usr/local/include/*
拷贝如下动态库文件到/home/liwei/ffmpeg_install/lib:
ffmpeg/libavcodec/libavcodec.so.53
ffmpeg/libavfilter/libavfilter.so.2
ffmpeg/libpostproc/libpostproc.so.52
ffmpeg/libavformat/libavformat.so.53
ffmpeg/libswresample/libswresample.so.0
ffmpeg/libavdevice/libavdevice.so.53
ffmpeg/libavutil/libavutil.so.51
ffmpeg/libswscale/libswscale.so.2
拷贝如下静态库文件到/home/liwei/ffmpeg_install/lib:
ffmpeg/libavcodec/libavcodec.a
ffmpeg/libavfilter/libavfilter.a
ffmpeg/libpostproc/libpostproc.a
ffmpeg/libavformat/libavformat.a
ffmpeg/libswresample/libswresample.a
ffmpeg/libavdevice/libavdevice.a
ffmpeg/libavutil/libavutil.a
ffmpeg/libswscale/libswscale.a
用arm-linux-strip工具去除动态库中的调试信息:
$cd /home/liwei/ffmpeg_install/lib/
$ arm-linux-strip *.so
