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=3Dcore2 CFLAGS=3D-O2 -pipe -march=3Dnative NO_CPU_CFLAGS=3Dyes COPTFLAGS=3D-O2 -pipe -march=3Dnative NO_CPU_COPTFLAGS=3Dyes 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= " > --=20 Olivier Smedts=A0 =A0 =A0 =A0 =A0 =A0 =A0 =A0 =A0 =A0 =A0 =A0 =A0 =A0 =A0 = =A0 =A0 =A0 =A0 =A0 =A0 =A0 =A0 =A0=A0 _ =A0 =A0 =A0 =A0 =A0 =A0 =A0 =A0 =A0 =A0 =A0 =A0 =A0 =A0 =A0 =A0 =A0 =A0 =A0= =A0 ASCII ribbon campaign ( ) e-mail: olivier@gid0.org=A0 =A0 =A0 =A0 - against HTML email & vCards=A0 X www: http://www.gid0.org=A0 =A0 - against proprietary attachments / \ =A0 "Il y a seulement 10 sortes de gens dans le monde : =A0 ceux qui comprennent le binaire, =A0 et ceux qui ne le comprennent pas."
