I've always checked supported OpenGL version by running:

if (GLEW_VERSION_3_0)

This seemed to work fine until I tried it on another computer. This computer is running Fedora 19 and the glewinfo executable reports up to version 4.0. However GLEW_VERSION_3_0 is false. I switched the keyword to GL_VERSION_3_0 and that seems to work better.

So what is the difference between these to variables?

Could it be this bug? http://sourceforge.net/p/glew/bugs/104/ – Kristian Duske Feb 08 '14 at 09:41
Oh.. yes. Quite possibly. But if I were to check that atleast one of GLEW_VERSION_3_0 or GL_VERSION_3_0 is true, would that be sufficient/safe? – bofjas Feb 08 '14 at 09:45
I don't know. Maybe you should ask on the Glew user forum what the exact meaning of these defines is? – Kristian Duske Feb 08 '14 at 10:15
