glGetIntegerv( GL_MAX_TEXTURE_UNITS_ARB) problem

[Jake]

Sorry for my 100th thread in the last few days, but I keep crashing on the glGetint line here


GLint maxTexelUnits; (class declaration)

maxTexelUnits = 1;
NSLog(@"%d",maxTexelUnits);
glGetIntegerv( GL_MAX_TEXTURE_UNITS_ARB, &maxTexelUnits );
NSLog(@"%d",maxTexelUnits);


Any ideas??? It worked in a NeHe example. I also have the same includes that they have.

It might not be safe to issue GL commands in your GLview subclass init called from awakeFromNib. Did you make the context current? Is the view visible on screen at that time?

That must be the problem, If I don't make another post assume that was the problem (it sounds like it is).

Thanks
