Hi everyone! I was starting to think to recompile everything for my pc to speed up everything. I started googling and I found almost nothing about how to change make.conf on bsd. Almost everything was about Gentoo, somehow not unsurprisingly. The first thing I noticed is that for linux all the instructions are about doing CFLAGS=" value" while it seems from /etc/share/examples/make.conf that in bsd I don't need ". Is it correct? Second question: If I set MAKEOPTS= -j 3 will that be used when portupgrading? (It's really to slow otherwise!) Third question...The most difficult..Which are the best flags for my machine? (freebsd 7.0-RELEASE with an intel centrino core2 duo) I have seen in the ..../examples/etc/make.conf that one of the possible "CPUTYPE" is core2 which looks to me as the right one but a geekier friend of mine that lives inside gentoo-linux told me that this option is unknown is gcc 4.2 and will be working from gcc4.3, so he told me to use "prescott". And what do I have to set to make gcc aware of the type of CPU I have? CPUTYPE= cpu and then CFLAGS= --O2 -pipe (etc..) or should I not write the cputype and then do: CLFAGS= -march=mycpu --O2 etc.... Can someone give me some advice on how to configure this file? Or can you provide me some documentation? Thank you!
