[FFmpeg-user] how to build ffmpeg into one static program without any dependent dynamic library

[qw]

Hi,


I use the following command to configure and build static ffmpeg :


./configure --disable-ffplay --disable-indev=sndio --disable-outdev=sndio \
--extra-libs='-static -L/usr/lib' --extra-cflags='--static' \
--enable-gpl --enable-stripping


make reports some warnings :
libavformat/libavformat.a(rtpproto.o): In function `rtp_resolve_host':
/export/qiang/buildDir/jdcloud_vod_ffmpeg/JD_FFmpeg/libavformat/rtpproto.c:140: warning: Using 'getaddrinfo' in statically linked applications requires at runtime the shared libraries from the glibc version used for linking
/usr/lib/gcc/x86_64-redhat-linux/4.8.5/../../../../lib64/libpthread.a(libpthread.o): In function `sem_open':
(.text+0x6a23): warning: the use of `mktemp' is dangerous, better use `mkstemp'
libavformat/libavformat.a(rtpproto.o): In function `rtp_resolve_host':
/export/qiang/buildDir/jdcloud_vod_ffmpeg/JD_FFmpeg/libavformat/rtpproto.c:140: warning: Using 'getaddrinfo' in statically linked applications requires at runtime the shared libraries from the glibc version used for linking

However, ffmpeg is static without any dependent dynamic library.


If I want to use Intel qsv codec, the option of '--enable-libmfx' should be added. Then configure will report error :
/bin/ld: cannot find -lva
/bin/ld: cannot find -lva-drm


The reason why it fails is that, there is no static libva library.


Can I specify which static libraries are used and which dynamic libraries are used to build ffmpeg?


Thanks!


Regards


Andrew
