[FFmpeg-user] Building ffmpeg and libx264 on ubuntu

[Alastair Mason]

Hi

I'm trying to build ffmpeg with libx264 on ubuntu 10.04. I have
followed this guide http://ubuntuforums.org/showthread.php?t=786095

but i get the following message on both the beta and the latest
version of ffmpeg:

CC    libavutil/x86/cpu.o
AR    libavutil/libavutil.a
CC    ffmpeg.o
ffmpeg.c: In function ‘term_exit’:

i have used this guide a number of times before successfully.
Googled but no luck on an answer.

the .configure:

./configure --enable-gpl --enable-version3 --enable-nonfree
--enable-postproc \
   --enable-libfaac --enable-libmp3lame --enable-libopencore-amrnb \
   --enable-libopencore-amrwb --enable-libtheora --enable-libvorbis \
   --enable-libvpx --enable-libx264 --enable-libxvid --enable-x11grab

Thanks for your help in advance
