Weird. It was looking for the object libraries at runtime, yet the filesize
was wicked huge. (I wonder what's up with that? It should only be a few Kb
in size.)
Now I just linked it a different way -- closer to what the Mesa demos do --
and it comes out nice and small -- 3360 bytes. (Unfortunately, it still
just gives a blank white window, same as before. :)

| libtool eh? What the heck is that? I seem to have it in /usr/local/bin but "man libtool" turns up nothing. I guess I'll have to read the man pages on gcc and ld to find out more about the shared libs vs static linking switches. Oh well, I was gonna (...) (25 years ago, 26-Jan-00, to lugnet.cad.dev)
