win, x86 mac, ppc mac and linux?
In theory, for things like wxMax, one could even say six, since static libs created on gcc on 10.4 and 10.5 won't play happy together.
looks like you've got the workings of a new BMax IDE
well, I'm in no hurry to take that direction!
Currently messing around with a small SQLite database manager, which lets me test wxCodeGen and a few of the wxMax controls (like wxScintilla, wxListCtrl, wxSheet, etc) - which otherwise won't be getting much work.
Half the problem is general take up isn't going to happen until it gets a proper release, where the code then gets exposed to a larger audience, and proper testing, which then highlights all the bugs that haven't appeared yet via the small set of developers currently trying it out.
I imagine this is the same for lots of projects though...
