test if OpenGL lib are present

[Vincent]

How can I know on Macintosh if OpenGL libraries are present. They must be a gestalt fonction.

In order for this to work, you need to "weak link" the stub libs. In CodeWarrior, click on the libs, open project inspector, and check "import weak"

if ((Ptr) kUnresolvedCFragSymbolAddress ==
(Ptr) glBegin)
{
// error, opengl not installed

}
