Running 32 bit apps on 64 bit OS


Just a couple questions I've been wondering about for a while. One, can a 64 bit Linux installation (FC7 x86_64, for example since thats what I'm using) run 32 bit binaries? Also, if you compile a program from source on a 64 bit OS, will the program then be 64 bit? Or does the program actually have to be written as 64 bit?

Yes, as far as I know, Fedore 7 x86_64 is a multi-lib distribution. It will run both 32-bit and 64-bit binaries.

The program you compile on a 64 bit OS will be 64-bit, to put it simple.
