Re: GNUstep on Darwin!

[John Davidorff Pell]

Here is my GNUstep tutorial so far, critics welcome:
http://gaelicwizard.kicks-ass.net/~pell/content.php?content=gnustep

The unresolved symbol is ___CFConstantStringClassReference its defined 
in CoreFoundation.framework, so i linked -base to with -framework 
CoreFoundation. It seemed OK... :-)

The tools from -base crash mostly with undefined symbols:
rest_world
save_world

And ideas? Is this related to the ObjC runtime?

the GNUstep libObjC library is actually build shared, not static, so it 
is named libobjc.dylib and its in /GNUstep/System/Library/Libraries

iBelieve that its being found correctly. An issue, -base has MANY 
undefined symbols from libobjc, so I added '-lobjc' to its compile 
line. Is this OK? Is it a bug? Or should it only be linked in when 
building binaries? Since libobjc is shared, iDon't think it matters. 
:-)

Where are 'rest_world' and 'save_world' defined??

P.S. iShould note that I'm using an "almost stock" apple compiler. I 
applied the bundle loading patch that was on the list a while back, 
AFAIK everything else is *identical* to stock. :-)
