[FFmpeg-devel] ffmpeg build error!

[Bombay Boy]

Hello Experts,
I am a newbie trying to build "ffmpeg" for Linux(Debian) for x86.
I got the latest source code from:
svn checkout svn://svn.mplayerhq.hu/ffmpeg/trunk ffmpeg

However, I try to build, I get the following error: Could you folks please help me how to resolve this?
?
