I am trying to test Objective-C on Linux (Ubuntu 10.04), mainly to decide if it's worth it to get a Mac and XCode. I have to like a language before I seriously consider programming in it (even more so when I have to pay a lot for it)
I am using gcc (with gobjc++). But this of course does not include the Foundation Kit and the rest of the Cocoa API (not overly concerned about this one).
Short of GNUStep, what is the best way for me to get into Obj-C programming in Linux or Windows? I want to get at least class in the FoundationKit.
