[PD] can't run Gem in Fedora with generic graphics (no GLX shader)?

[Miller Puckette]

Hi all,

I've been trying to compile and run Gem on my Fedora 5 box, i386, clean
install, on-board Intel graphics.  Gem fails to load complaining as follows:

$ pd/bin/pd -nogui -lib Gem/src/Gem
./Gem/src/Gem.pd_linux: ./Gem/src/Gem.pd_linux: undefined symbol:
+glGetShaderInfoLog
Gem/src/Gem: can't load library

Gem works fine on another machine I'm using with the proprietry nvidia
driver.  Is there a way to either: (1) install the "GLX shader" extension
on generic hardware, or (2) compile Gem with "shading" disabled?

thanks
Miller
