yes, because the USE flag is something completly different from the CFLAG > > Or is it selected automaticly by that -march=athlon-xp ? it is selected by march for the CFLAGS, but some apps have additional optimiziations built in, that have to be activated with configure options. That is where the USE flags come to action. So, set them in the useflags too, there are some apps that use them for better performance. -- gentoo-user@gentoo.org mailing list
