We seem to have VERY diff sets of information.

I tried to compile GNUstep on MacOSX from cvs HEAD only a few weeks ago. For my full procedure, go to: http://gaelicwizard.kicks-ass.net/~pell/content.php?content=gnustep

If you ignore the opinions (which from your email seems to be unlikely, no offense), you'll find that there is a whole lot that I had to do to get a GNUstep-base to compile in a usable way, including compiling GNU's objc runtime. GNUSTEP BASE WILL NOT WORK ON APPLE's RUNTIME! The "additions" do compile, but then I don't have a working GNUstep-base, and no DO.

FYI, I have never used, nor know anyone who uses, ONLY GNUstep-base. I'm talking about GNUstep as in ALL OG GNUStep, including GNUstep-gui.

Also you info about libffi is not really correct, the source in GCC do work, just not the ones
in any released versions (read 3.4).

Also GDB (I think 6.0 that is) now supports Objective-C without downloading a patch.

We (GNUStep but I am not really part of this we) know (and so does GCC for that fact, I am working on it) that GNU's libobjc is hard to compile on Darwin (aka Mac OS X). Also the reason why GNUStep Base does not work with NeXT (Apple)'s runtime, it was made
as a replacement on other platforms not on the NeXT (or Apple).

I think you should read some history about GNU's Objective-C and GNUStep to see why they did this (also GNUStep is an implementation of the OpenStep specs and not Cocoa
which has extensions upon the OpenStep specs).
