It also comes with instructions on compiling Windows apps on XCode, but not any other platform. Although it is probably possible to compile it on other platforms, it comes XCode project files, not makefiles, so you can only compile its frameworks out of the box on OS X. However, GNUStep does compile from just about any platform.

I was not able to use Objective-C++ with GNUStep a few years ago. I haven't tested those features with GNUStep, but if you use a sufficiently new version of gcc, you might be able to use them. Because GNUStep typically uses the latest version of gcc, they also add in support for Objective-C++ and a lot of the Objective-C 2.0 features. Their aim is to keep Cocotron up to date with the latest version of OS X so that any viable OS X program can run on Windows.

However, if you want the Cocoa frameworks, or at least a reasonable subset of them, then GNUStep and Cocotron are your best bets.Ĭocotron implements a lot of stuff that GNUStep does not, such as CoreGraphics and CoreData, though I can't vouch for how complete their implementation is on a specific framework. You can use it through Cygwin or get MinGW. Expanding on the two previous answers, if you just want Objective-C but not any of the Cocoa frameworks, then gcc will work on any platform.
