Compiling on one computer, installing/running on another

Would this be possible to do? I assume it would be as long as your CFLAGS aren't set to your processor. Can a P4 compile specifically for a AMD-K6 II? Or would it just need a generic x86 compilation?

I'd like to be able to do this because my computer is much faster than the one I need to install a few programs on.

You should look into using distcc. It's not very difficult to set up. Then you can put some or (almost)all of the load on the faster machine. And it doesn't matter what the cflags are on the fast machine, the compiler options get set for the machine doing the emerge. But yes you can compile optimized binaries for any x86 cpu on any other, as long as the compile process doesn't require running anything that you compiled. I other words configure scripts would be a problem. I'm not sure if k6-2 optimized binaries will run on a p4 or not. I know they will run on any later amd cpu but I suspect a p4 would give you problems. But you could use i586+mmx optimization. That would run on either cpu fine. But you wouldn't be taking advantage of the k6-2's full capabilities.

Thanks, I'll look into distcc.

I second Distcc. Great way to compile on slow machines. The more boxes you throw in the faster it gets. I have 7 computers in my house and I use them all when I compile. Open Office only takes about an hour or so this way as oppsed to the 11 or so it takes my pentium 4 to do on its own.

You can also use the Gentoo reference packages which are superb. They are the way to go if you have a slow connection, slow computer or just want to install fast like an RPM distro. The instructions are included in the installation documents.
