well, your problem has been introduced by the [glsl_*]-objects, whichare using openGL-2.0 features. your options are: install an openGL that supports openGL-2.0 specs. (if you have an nvidia-card, install the nvidia-glx(-devel) packages; else i don't know (so you are probably out of luck)) OR remove following files from the Gem-sources: src/Manips/glsl_*.{cpp,h,o} src/openGL/GEMglUniform*.{cpp,h,o} and recompile
I did what you suggested and recompiled Gem successfully, -lib Gem loads and seems to work fine. Just one last question-- by having removed the above files, what functions in Gem am I sacrificing? Thanks again, /Brad.
