OpenGL programs generator a glide error on Voodoo4/5 cards

From Bugzilla Helper: User-Agent: Mozilla/5.0 (X11; U; Linux 2.4.2-0.1.49 i686; en-US; 0.7) Gecko/20010316 The libglide3.so in XFree86-libs-4.0.3-5 has a bug when used on a Voodoo4/5 graphics accellerator w/ OpenGL software. Specifically, the error message is: gd error (glide): gd error (glide): grSstSelect: non-existent SSTgd error (glide): grSstSelect: non-existent SSTSegmentation fault (core dumped) A good example for reliably generating this error is tuxracer. Reproducible: Always Steps to Reproduce: 1. Combine the libglide3.so from XFree86-libs-4.0.3-5 with a Voodoo5 card. 2. Run an OpenGL program. Actual Results: The above error Expected Results: The program should run. There is an RPM for SuSe linux that contains just the libglide3.so compiled w/ proper 3dFX support, however even that libglide3 isn't flawless. Better to fix the XFree86-libs version.
There are *two* glide libraries for XFree86-4.0.3. One is for Voodoo 3, and the other for Voodoo 5. I dunno which one Voodoo 4 is supposed to use however as I have no 3dfx cards to test with. Upon installation, there is a symlink pointing from: /usr/lib/libglide3.so.3.10.0 to /usr/lib/glide/libglide3-v3.so You need to manually change the symlink to point to the voodoo 5 library by doing: "cd /usr/lib ; ln -sf glide/libglide3-v5.so libglide3.so.3.10.0" Make sure the link was made correctly, run "ldconfig", and it should work. This should all be done by Xconfigurator I suppose, so I'm reassigning it there.
Well, I did as you suggested and linked /usr/lib/glide3/libglide3-v5.so to /usr/lib/libglide3.so.3.10.0 and I no longer get that error. Instead I get some very pretty but very non-working results when I run an OpenGL program. To describe it, it looks something like the northern lights.. A very colorful blob starting from a single pixel in the lower left corner of the display window and expanding up and to the right (kind of like a spotlight) would be a more accure description. I haven't got the slightest idea why, but that's what it's doing now.

The above attachment is a screen capture of a window that exibits these problems. XMMS has an OpenGL Spectrum Analyzer as one of its visualization plugins. You'll be able to view the expected results of running that. error.png shows what I get.
