i am working on shadow mapping for my opengl 3d environment (just a simple room at the moment); and i am getting problems with the following statement glCopyTexImage2DEXT(GL_TEXTURE_2D, 0, GL_DEPTH_COMPONENT16_SGIX,0, 0, x, y, 0); i am getting two errors at the moment these are error C2065: 'GL_DEPTH_COMPONENT16_SGIX' : undeclared identifier error C3861: 'glCopyTexImage2DEXT': identifier not found, even with argument-dependent lookup at first i thought it was because my machine didnt support the extensions as it was running opengl 1.1 but i am getting the same problem with my mates machine running opengl 1.5, if anyone has encountered this problem before or quite simply knows whats wrong please could you help me

Post the configuration of the machine and the graphics card u r using.
Also some code would help debug the problem.

Use a decent library to load all of the extensions supported by your card.
GLEE 5.03 (built and maintained by Phantom) is the caviar of GL libs, of course all according to my perspective :)
