You should be specifying '-march=athlon64'. '-athlon64' is not a valid CFLAG, also -sse/2 and -3dnow are all implied by -march=athlon64 and I'm quite sure that -mfpmath=sse is also the default on amd64. It may be useful to specify '-msse3' in the CFLAGS though if your cpu supports SSE3 as no -march setting implies it yet. Although it's unlikely that gcc utilises sse3 properly. I recommend the following CFLAGS: CFLAGS="-O2 -march=athlon64 -pipe" Adding -msse3 if appropriate for your cpu. > > Those were the options I used, and from what I can see you did indeed > download the proper image for your processor (provided it is an AMD > Athlon 64 X2 Dual Core system). > > Regards, > Chris -- Raymond Lewis Rebbeck -- gentoo-user@gentoo.org mailing list
