It say's not to use Athlon-4. I'm not even sure what that is, but the make.conf file has an example with athlon-xp so I would assume it's ok. Jason Ted Ozolins wrote: Mike Williams wrote: On Tue, 2003-03-04 at 20:44, Jason Giangrande wrote: Anyone have any examples of the CFLAGS and CXXFLA

I don't believe there are any other differecnces between the XP and MP and some early XP's didn't have the smp capability disabled, so, I would imagine, they are exactly like MP's. Jason Ted Goodridge, Jr wrote: ->Physically, I believe, the CPUs are the same. i.e. you can do SMP with 2 ->XP's

Thanks for the link. Do you know what "-fomit-frame-pointer" does? It's one of the recommend flags for pretty much every processor. Jason Dhruba Bandopadhyay wrote: Jason Giangrande said: Anyone have any examples of the CFLAGS and CXXFLAGS settings for a dual Athlon system or know of any l

It depends on the Athlon. AMD has XP and MP versions of the cpus. Richard may have the XP version. Since I have the MP version I used it. On Tue, 04 Mar 2003 16:04:08 -0500 Jason Giangrande <[EMAIL PROTECTED]> wrote: Thanks. Quick question, though. Why athlon-xp instead of athlon-mp? Jas

It tells make how many processes it can run in parallel. Usually the number of cpus plus 1 is recommended. On Tue, 4 Mar 2003 21:11:31 - (GMT) "Dhruba Bandopadhyay" <[EMAIL PROTECTED]> wrote: Richard Kilgore said: CHOST="i686-pc-linux-gnu" CFLAGS="-march=athlon-xp -mcpu=athlon-xp -O3
