As far as I can tell, GNUStep hasn't worked properly in the last 3 versions of Ubuntu (including 11.04) amd64.
I am using the GNUStep packages from Ubuntu's repository.
I just downloaded and compiled ProjectCenter 0.60. It compiles fine, but when I try to run it, I get an error:
Downloads/ProjectCenter-0.6.0$ openapp ./ProjectCenter Downloads/ProjectCenter-0.6.0/ProjectCenter.app/ProjectCenter: error while loading shared libraries: libProjectCenter.so.0: cannot open shared object file: No such file or directory
When I try to run the version of ProjectCenter in the Ubuntu repository, I get this:
2011-05-21 12:34:05.481 ProjectCenter Did not find correct version of backend (libgnustep-back-018.bundle), falling back to std (libgnustep-back.bundle).
2011-05-21 12:34:05.691 ProjectCenter NSApplication.m:304 Assertion failed in initialize_gnustep_backend. Unable to find backend back ProjectCenter: Uncaught exception NSInternalInconsistencyException, reason: NSApplication.m:304 Assertion failed in initialize_gnustep_backend. Unable to find backend back
Gorm and SystemPreferences give similar errors.
I haven't been able to get anything (Gorm, SystemPreferences, etc.) running on the two previous versions of Ubuntu either (10.10 and 10.04).
