Hi,
I have recently tried to build an mplayer snapshot, which pulls ffmpeg
git. Unfortunately, it is impossible to build it with gcc-4.7 prerelease,
which Fedora switched to:
{{{
ffmpeg/libavcodec/libavcodec.a(ffv1.o): In function `encode_init':
/builddir/build/BUILD/mplayer-
export-2012-02-26/ffmpeg/libavcodec/ffv1.c:1041: undefined reference to
`__builtin_iround'
collect2: error: ld returned 1 exit status
make: *** [mplayer] Error 1
make: *** Waiting for unfinished jobs....

`__builtin_iround'
collect2: error: ld returned 1 exit status
make: *** [mencoder] Error 1
}}}
Any ideas on how to fix this? Or is it perhaps a gcc error? Cheers.
