Does OGo directly depend on the libFoundation library or can the gnustep-base library used as a replacement?
OGo has little dependencies on libFoundation, instead it tries to follow the Foundation API as described in the OpenStep standard. Nevertheless it won’t compile with gstep-base out of the box, some minor tweaks are probably necessary. We are very interested in someone contributing a gnustep-base port of OGo, since this will give us two things required: full Unicode support and a better base for porting OGo to Windows. So if you are interested in porting to GNUstep, please send mail to contribute@opengroupware.org! Sidenote: the strategy for porting to MacOSX is to actually use the Cocoa Foundation library and the Cocoa Objective-C runtime instead of libFoundation. Everything up to SOPE already works on MacOSX.
