C++ for Macs possible?

#1 OS 5?? Goodness man, that's far too old to even consider using now. That version was around in the '80s.

Now, there are only two Mac OSes a developer should be looking at: 9.2 and 10.1.

9.2 is the latest (and probably last) incarnation of the classic Mac operating system. People still program for it using an API called Carbon, simply for compatibility with people who don't have OS 10 yet.

Mac OS 10.1 is the latest operating system, and is completely rebuilt from the ground up over the Unix kernel, with a whole bunch of tightly layered technologies built-in, OpenGL being one of them.

In terms of compilers, if you're using OS 9.2 or below, you should go with Codewarrior from Metrowerks. That's long been the most compatible compiler for Mac. But, it costs.

If you seriously plan to program for the Mac, get OS 10.1. With it, Apple includes their free IDE and compiler called Project Builder. Not only is this a better package than CodeWarrior, but it is made by Apple for guaranteed compatibility, includes ALL APIs and SDKs to program for their new OS, and takes full advantage of well, everything.

You won't find anybody using OSes 5, 6, 7, maybe even 8 anymore. Heck, the first two on that list were black-and-white only, and 7 was the first to introduce multitasking. :P

#2 The problem is I'm designing an app for a Primary School, they don't have the latest and greatest...

I'm hoping they've got something round 8, but I know for certain they don't have anything higher than that :(

Thanks for the link to metrowerks :)
