Can't use GCC in OS X Terminal

Question

I have installed the developer tools. I can compile code via Xcode and according to the docs /usr/bin/gcc & /usr/bin/cc should point to /usr/bin/gcc-4.0. Neither the symlinks or gcc-4.0 exist on my system (Snow Leopard). All I wish to do is compile some C on the terminal! I'm amazed by how complicated this task is. The command GCC is unsurprisingly returning "gcc: command not found".

Can anyone shed some light on this?

Answer 1

Did you install the latest Xcode after installing Snow Leopard, or is this the version of Xcode from a previous OS installation?

On my system with a clean Snow Leopard install the default compiler (and the one symlinked from cc and gcc) is gcc-4.2

I do have gcc-4.0 too, although it's not the default.

Answer 2

No! Reinstalling is the wrong answer!

Newer versions of XCode require you to install the command-line versions of the tools separately. In XCode, go to Preferences | Downloads, check the Components tab, and install them from there:

Answer 3

These binaries should be there after installing xcode. Check your path settings, and if you still don't have these reinstall xcode

Answer 4

Command line tools are no longer included with the latest XCode (even as an add on). Now you can download them here:
