Are they the cmov instructions my cpu doesn't support? The thing is that the wiki said setting CHOST=i686.. was OK because gcc would figure out what instructions not to use when I pass -march=c3. > mjpegtools does have a fmax() that it will compile and use if the > system does not have one. > > In config.h perhaps changing > > #define HAVE_FMAX 1 > > to > > #undef HAVE_FMAX > > will work. On the other hand that could just result in a multiply > defined symol where fmax() clashes between mjpegtools and libc. I'm going to recompile the box with CHOST=i586-.. because I if that's the issue there's probably more breakage that I haven't found out about yet - and I don't need that. If it doesn't help I'll try the FMAX stuff. Thanks for you input, Steven! Regards Sebastian ------------------------------------------------------------------------- Take Surveys. Earn Cash.
