64 bit programs

I have just recently bought a 64 bit computer and want to take full advantage of it's power.

Is there a C compiler that will compile source code into a 64 bit program? (for Linux)

There are several.

I would recommend gcc, as it a) is competitive in terms of optimizing power and b) is a standard compiler for Linux. So long as you have installed the 64-bit version of a Linux distro, it should be installed by default.

Tip: Always compile production code with -O3 for speed, and development code with -Wall to trap common mistakes. You can also set various other flags to tweak the speed of your program; see the manpage.

Code:

man gcc
