I googled, and found something like this:
char *p;
p = (char *)glGetString(GL_VERSION);
if (p == NULL) {
printf("none");
return;
};
printf(".%3c.
", p);
Unfortunatley, p is always NULL. Any idea why?

You need a valid and working context for this to work.
EDIT: didn’t noticed it: %s should be best in your printf.
A bit off-topic: any ideas how I can get graphic driver version in run-time?
More exactly, a Linux application needs to determine the following two things:
A minor detail - this should be done before a rendering context is created - thus I cannot rely on the all-mighty glGetString().
Thanks in advance!
create a context from a temporary window.
The problem is that there is no way to know what driver will be used until you have a context because the type of context requested might depend on a specific driver or might have to fall back on software rendering.
