Um, Build Modules on a Mac?

I finally splashed out on an iMac and want to test my BlitzMax apps on it. Trouble is when I click Build Modules or Rebuild All Modules, i get the following error:

Building Modules
Compiling:blitz_app.c
sh: line 1: gcc: command not found
Build Error: failed to compile /Applications/BlitzMax/mod/brl.mod/blitz.mod/blitz_app.c
Process complete

Can anyone tell me what I need to do?

BTW i'm using Mac OS X, 10.4.8.

You need to install XCode, I know that much. Also, on my Mac, even with XCode installed back in the day, I managed to screw up the env variables somehow with some GUI app that was supposed to make setting the env variables "easier". I Uninstalled that program, and it worked for me. Otherwise.....you'll have to wait for someone with more uber Mac knowledge to respond!

Yah install xcode it includes gcc and other bits needed to compile - libraries and frameworks, etc.

Contrary to popular belief you don't need to install ALL of the xcode package because that's more than a Gig of needed space, I was able to get max to compile with about 300k of xcode packages installed.

But, I'd recommend all of XCode, there's lots of cool stuff.

Its free from Apple's site, and it should be on a disk with the computer.

I installed it (fully) and now the modules are buildign. Thanks, chaps. :)

Yah it's good to have it all if you have the space. I had to trim it down to 300k on a 3 gig harddrive.
