I am trying to upgrade the installed OpenGL version from v1.1 to 1.2+. I am running Red Hat AS 4. How does OpenGL get updated? Does upgrading the NVidia drivers "automatically" update the OpenGL version, if so what is the library and include path to use this version of OpenGL for programming? If not, is the Mesa version of OpenGL sufficient for Linux? Just for information: this box does not and cannot connect to the internet for downloads, so using the Red Hat Network is out of the question. I have contacted Red Hat, but they just said they can only provide the Mesa versions of OpenGL.
