[gst-devel] problem compiling gst-ffmpeg under gentoo with cpu that doesnt support sse

[Matt Henley]

i am using gentoo on an old athlon tbird.  It doesnt support sse
although configure scripts happily report that it does.  Therefore I
have added  -mno-sse -mno-sse2 to my make.conf.  When I try to compile
 the gst plugin gst-ffmpeg I get the following:

Is there a switch that will tell it not to use sse?
