*SOME* of the flags listed on /proc/cpuinfo can be used with make.conf CFLAGS. You have to check the gcc documentation to confirm which flags can be used. If you are running gcc-3.3.5, check the page... http://gcc.gnu.org/onlinedocs/gcc-3.3.5/gcc/i386-and-x86_002d64-Options.html#i386-and-x86_002d64-Options Also *SOME* of the flags in listed on /proc/cpuinfo can be used in make.conf USE variable. This applies to mmx and sse and a few others. See http://www.gentoo.org/dyn/use-index.xml for a list of valid USE flags. Here are the CFLAGS and USE lines from my make.conf on my Pentium III. CFLAGS="-O2 -march=pentium3 -fomit-frame-pointer -mmmx -msse -mfpmath=sse" USE="-X -acl acpi alsa audiofile avi -berkdb -bidi dga dvd encode exif -fam flac gif gnome -gtk -ipv6 jpeg -kde -ldap mikmod mmx -nis -nls -odbc offensive oggvorbis openal opengl -pam plotutils png posix -qt quicktime slang sndfile -snmp -soap -speex -spell sse -tcltk tcpd theora -unicode usb videos wmf -xplc xvid zlib" Try "cat /proc/cpuinfo > cpu.txt" on your machine and post the contents of cpu.txt here, and we can advise you which flags to use. -- Walter Dnes <[EMAIL PROTECTED]> An infinite number of monkeys pounding away on keyboards will eventually produce a report showing that Windows is more secure, and has a lower TCO, than linux. -- gentoo-user@gentoo.org mailing list
