I suspect that this has to do with the GNUstep installation I compiled myself
and the available (nouveau?) NVIDIA drivers.
Again, compiling and running ProjectCenter and Gorm is ok. But this OpenGl
stuff completely fails.
Any suggestions how to prevent this error from happening on OpenSUSE .4?
Your current problem is with GNUstep back, this doesn't seem to detect
any OpenGl stuff. Could you please post the config.log file in your back
directory?
I am using OpenSuse 11.4 myself but haven't used OpenGl with GNUstep.
When checking my own config.log file I noticed that both the tests for
OpenGl fail. The first one for the library because my system seems to
lack the symbolic link libGL.so to libGL.so.1. And the second one as
there isn't any header file named GL/glx.h. There is one called
GL/glATI.h though. If things are similar on your system just adding a
few symbolic links might help. I will try that myself and see whether
configure will now correctly detect OpenGl.
