glColorTableEXT() problem

I’m getting linking error for the function glColorTableEXT(). I have included gl.h & glext.h but the program is unable to find an implementation for the function.

I believe I need opengl 1.2 version for this but I have only 1.1 in my computer.

My graphics card is GeForce 3 & I have downloaded the Nvidia drivers. But the problem persists. Nvidia’a openGL SDK does not contain opengl32.lib or .dll file.
