I assume that's a stock Suse 9.2.

OK, the extensions is here.

Hm, ok so you do have the old, non-nVidia OpenGL libs still there. That
shouldn't be a problem, but just in case, can you try calling ldd on
your executable?

OK, makes sense.

OK, there are no changes after that.

I'm stumped! The driver is reasonably up-to-date, and it says that the
usual extensions are supported, but then when you ask for any actual
function all you get is NULL! This doesn't make sense at all!
Can you run any other OpenSG applications, or any other applications
that use extensions? Is anybody else using a Suse 9.2 with a Quadro 4
that could confirm this problem?
I attached a small patch for OSGWindow.cpp, can you please apply that
and try it again, it should give a little more information about what's
going on.
Thanks
Dirk
