slackware compile flags

sh1ft · 12-16-2004, 11:04 PM

I remember when I was using gentoo, there was the ability to set the gcc compile flags to optimize for my specific cpu (-march=pentium4)

I'm wondering how I could set a system wide flag in the same manner on slackware, so whatever programs I compile from source will have that negligible boost it gives(more so for the warm feeling I get believing I'm getting the most out of my apps) . I guess it's not so much a distro question as a gcc question.

For system wide settings, I would put :

CFLAGS="-march=pentium4" # or whatever settings you want
CXXFLAGS="$CFLAGS"
CHOST="i686-pc-linux-gnu"

export CFLAGS CXXFLAGS CHOST

in /etc/profile, say at the bottom of the file

You could also put the above in your .bash_profile or .bashrc file for a specific user (although compile flags are something that should be system wide).

Thanks that was exactly what I was looking for.
