Yuk! Your libs and mine are not setup anywhere near the same way.
I have NOTHING in /usr/local/lib. All the X stuff is in /usr/X11R6/lib.
The Mesalibs were already there when I installed off the Mandrake CD so
I left them there, even though the Mesa docs that came off the Mandrake CD
say to put them in /usr/local/lib. When I downloaded the ldglite zip file
I got a link error since the GL softlinks weren't there. This is what I
did. Shoot me if I did it wrong, but it seems to work for me.
[dheyse@localhost lib]$ cd /usr/X11R6/lib

[root@localhost lib]# ls -l *GL*

I cut out all the middleman soft links and hooked libGL.so straight to
LibMesaGL.so.3.1
Same for libGLU.so
libglut.so was there already so I left it alone.
Anyways, after I made those two softlinks I could link ldglite and
it just worked. Did you try removing the executable and relinking?
I didn't provide a "make clean" in the makefile yet so you have to do
that by hand.
Hmmm, I have redhat 5.2 on a 486 somewhere. Perhaps I'll try installing
Mesa from scratch on that and see what happens.

| I just thought of another thing to try. In main.c search for #ifdef DRAW_AXIS. Put this right above it. #define DRAW_AXIS 1 This will draw the x,y,z axis in red, green, and blue like in the gif file on the website. That'll show if GL is working. I (...)
