Re: porting cocoafibs, trouble with nibs

[Fred Kiefer]

Nice thing that you are doing here. Your main problem seems to be that
GNUstep currently does not support NSController and its subclasses (in
your case NSUserDefaultsController). With that missing your NIB file
will never work, which ever way you convert it.
I see two ways to proceed: Either you manage to remove the need for that
class from the original NIB file or we need to add that class somewhere.
I have some basic implementation for some of the controller classes
lying around here, but I never committed them to GNUstep as not to bloat
our code with unused classes.

Cheers
Fred
