What flags should I use for compatibility?

Festy

I have a network with 6 computers I want to run Gentoo on:

Pentium III 700
Pentium III 667
Athlon XP 2100+
Athlon Tbird 1400
Duron 900
K6/2 500

What compiling flags would I have to use in the make.conf to make every package i compile on one system (which will then be put into a common package directory) work on every other system, so to allow for fast as possible installs for anything that has been compiled on another system?

Thanks

Burn.

You would have to set :
CHOST="i586-pc-linux-gnu"
CFLAGS="-march=i586"

You can add about everything to CFLAGS not related to CPU type.
You could add "-pipe -O2 -fomit-frame-pointer" for example, but not "-msse".

Note that only the K6 is i586, all other are i686, and I think they all support sse, so maybe you want to split up the 4 big machines, and the slowest one.

On each computer you could also add -mcpu=<...>(athlon-xp for example)., to make the code optimized for that cpu, but still allowing it to run on others.
