I tried:
 GLUT.Init;
 GLUT.InitDisplayMode(GLUT.SINGLE);
 strVersionptr := gl.GetString(GL.VENDOR);

but the same problem occurred.
I'm wondering if it wants a window set up?
I don't think it should, as output to console is needed?
I not really sure what the InitDisplayMode should be set to; but I think GLUT.SINGLE should be OK!
