GLX X-extensions on AIX4.3.3

I am new to OpenGL.
I am re-compiling a c graphic program developed in AIX3.2 with Motif2.1 and OpenGL in the AIX4.3.3. The AIX4.3.3 release does not state explicitly whether it supports the GLX X-extensions. It only addressed that the functions in GL/utilities/ are not going to be supported. I got the message"Xlib: GLX is missing in display:0.0" when I run the program. (It passed the compilation)

Can anyone help me?
