I have been writing quite a lot of OPenGL in Ada using GLOBE_3D.
However, I have just tried to "Checking for OpenGL functionality" as described in Apple's OpenGL Programming Guide for Mac.
However, gl.GetString(GL.VENDOR) and other calls to gl.GetString result in:
raised CONSTRAINT_ERROR : erroneous memory access
even if gl.GetString(GL.VENDOR) is in the only instruction in the program.
Any ideas on what's causing this will be appreciated.
Roger
