porting cocoafibs, trouble with nibs

[Paddy Smith]

Hi,

we are attempting to port cocoafibs
(http://sourceforge.net/projects/cocoafibs/) to gnustep at
http://sourceforge.net/projects/stepfibs/

converting the nib files is giving us trouble.

One of them, the Invite nib will go through nib2gmodel.  the resulting
gmodel will load in gorm (1.1.0 built against the gnustep in debian
sid). the nib that gorm emits from that will not load in the macosx IB
(xcode2.4), giving the error "-[NSPlaceHolderMutableString
initWithString]: nil argument "

which is interesting because trying to load the macosx nib directly
(saved out to xml) in gorm results in the error "Exception
-initWithSring: given nil string".

There are errors with other nibs like "no class for name
'NSUserDefaultsController'".

[incidentally, it would be really nice to be able to cut'n'paste these
errors off the gorm gui]

the original source in question can be got from the cocoafibs cvs on
sourceforge, but the nibs there are in the binary format. I have
posted the macosx IB output of those nibs in the xml format and the
Invite nib output from gorm mentioned above on the stepfibs
sourceforge under Files.

So, help, suggestions, advice, encouragement, etc. all gratefully received :-)

What do people suggest: should we stick with nibs, or use renaissance,
or something else ?

Any suggestions on how to convert nibs to renaissance?  is there a
program to do this ?

Regards,
Paddy
