Yep - it certainly does. V.impressive.

Well, it would be more usual to link them in the order:

    -lglut -lGLU -lGL -L/usr/X11R6/lib -lX11 -lXi -lXext -lXmu

...since glut uses both GLU and GL functions, GLU uses only GL functions, and
GL doesn't use either of the others.

But I'd have thought that if it got through the linker OK, you'd be
alright.  The linking process is getting so damned complicated these
days that I'd believe anything - so try relinking your program with
the libraries in that order.

Or just run 'gdb' on the core file and type 'where' to get a stack
backtrace.

It certainly wasn't necessary for me.  I installed the nVidia drivers
over the top of Mesa - and Mesa's GLU "just worked".

I didn't recompile it or anything...and I've not had any crashes at
all.  Having said that, I'm not a *heavy* user of GLU - so I may well
not be exercising the part that's giving you problems.

If you are desperate, you could try the GLU that comes with the
SGI reference implementation of OpenGL - but I don't think that
should be necessary - and it would be nice to track this one
down first.
