Hi all, I have a Core2Duo T5600 1,83 MHz in my notebook. Today I read on the GentooWeeklyNewsletter to use "-march=nocona (and an amd64 profile) for Core 2 Solo/Duo"
Currently I'm using: CFLAGS="-O2 -march=pentium-m -pipe" CHOST="i686-pc-linux-gnu" CXXFLAGS="${CFLAGS}" MAKEOPTS="-j3" and /usr/portage/profiles/default-linux/x86/2006.1/desktop/ as profile and gcc -v told me I'm using 4.1.1-r1 Now my questions: 1. What wold be the benefits of chanching the CFLAGS? 2. After chanching do I have to emerge everithing again? or what should I do? 3. They mentiont to use a amd64 profile, does this mean to use 64bit? because I would like to stay with 32bit. 4. I used gcc -v to check the gcc verison I'm using, is this the rigth command? Thanks for any help Jakob
