Jack's problem did not occur during compilation but rather when trying to load a shader. There are still a large number of shaders that will run on his hardware although not as fast as they would with more current hardware. The error and handling are in line with the spec and worked as designed in this case.
<br><br>GEM defaults to a basic level of hardware which is still very conservative (probably 5 years out of date or ancient in GPU terms). Most of the feature support issues come from open source drivers for fully compliant hardware (mesa ATI) or incomplete hardware that masquerades as a full GPU (Intel).

This happened to me too. I had to track down the Gem objects using<br>"glsl", delete them, and recompile Gem.<br><br>An alternative is to use the "--with-glversion" switch; this appeared<br>on an earlier thread,
