Building frameworks on GNUstep Windows

[Andreas Höschler]

Hello all,

we have installed GNUstep base on Windows using the the binary 
installer (good work) and even managed to build gui. However, we 
encounter problems while porting our frameworks to windows. Building 
any framework gives us

...
SRManager.m: undefined reference to '__objc_class_name_NSString'
SRManager.m: undefined reference to '__objc_class_name_NSData'
SRManager.m: undefined reference to '__objc_class_name_NSArray'
C:\GNUstep\Development\msys\1.0\mingw\bin\dllwrap.exe: no export 
definition file provided.
Creating one. This might not what you want.

Any idea what this means and how this can be fixed? The same makefile 
works great on Linux and Solaris. Has anybody ever managed to build a 
framework under GNUstep windows?

Thanks a lot!

Regards,

  Andreas
