Fri Dec 16 08:51:59 UTC 2011

Hi
I have two computer installed FC16 on them. On the First FC16x86-64
installed and on the other FC16-i386 installed.
Can I compile some program on one and run on the other?
I want to compile my program on 64 bit os and run on 32bit os or vice versa.

any suggestion or guideline for me?
