AMD64, Gentoo = Compile Errors

[bleh]

Try removing "-march=i686". If it compiles, try more specific ones from gcc man page. Also try option -m64.

edit: I haven't compiled 64-bit version

Heh,

Yeah i figured as much, and just built a 32 bit binary, works
Who am I to argue with results. And I actually bet its faster for my
1-client setup (at the very least the performance gain is negligible).

Yeah, have to watch those CFLAGS

I myself only add one at a time and run a test compile... add another, repeat... etc. as I tweak out my Gentoo systems.

I think the proper gcc -march flag for amd64 would be -march=k8. At least that is what I use in my /etc/make.conf for all my amd64 gentoo servers at work. My gentoo box that I run eqemu on is an old 1 Gig athlon-tbird. I make sure to change all of the makefiles to reflect this by switching -march=i686 to -march=athon-tbird and -O to -O2. The same settings that I use in make.conf. I also make sure to remove the -pg flags while I am in the makefiles. I have yet to have a compile error "knock no wood"...

Here is a helpful guide on the gentoo wiki about cflags http://gentoo-wiki.com/Safe_Cflags

Sounds like a good balance, Cubber
