[vlc-devel] failure in building ffmpeg-20051126

[Yan Lu]

Hi 

 

I'm intending to build ffmpeg-20051126 using cygwin with
contrib-20051208-gcc3.3.3-only. I have got error: framehook.c:50:
`RTLD_NOW' undeclared (first use in this function)

I have changed "dlfcn=no" to "dlfcn=yes" in "configure" file, and then I
was able to successful built libavcodec.a and libavformat.a. But I was
failure in building ffmpeg_g.exe, and I have got errors: 

ffmpeg.o: In function `av_encode':

/home/ffmpeg-20051126/ffmpeg.c:2133: undefined reference to `_fifo_free'

The script used for building ffmpeg is such as: 

./configure --enable-mingw32 --enable-memalign-hack \

                --extra-cflags=-I/usr/win32/include
--extra-ldflags=-L/usr/win32/lib \

--prefix=/usr/win32 \

--cc="gcc -mno-cygwin" \

--enable-faac --enable-mp3lame --enable-pp --enable-gpl \

--enable-amr_nb --enable-amr_wb \
