Maybe this is a documentation bug with > .../share/examples/etc/make.conf ? CPYTYPE is make.conf and -march in gcc are different things. After a lot of reading (/usr/share/examples/etc/make.conf and man gcc) and testing, here is what I use for my core2 : CPUTYPE=core2 CFLAGS=-O2 -pipe -march=native NO_CPU_CFLAGS=yes COPTFLAGS=-O2 -pipe -march=native NO_CPU_COPTFLAGS=yes I think you can use the same for your i5. > Thanks, > -Garrett > _______________________________________________ > freebsd-hackers@freebsd.org mailing list > http://lists.freebsd.org/mailman/listinfo/freebsd-hackers > To unsubscribe, send any mail to "freebsd-hackers-unsubscribe@freebsd.org" > -- Olivier Smedts _ ASCII ribbon campaign ( ) e-mail: olivier@gid0.org - against HTML email & vCards X www: http://www.gid0.org - against proprietary attachments / \ "Il y a seulement 10 sortes de gens dans le monde : ceux qui comprennent le binaire, et ceux qui ne le comprennent pas."
