I recently attempted to compile winex. It kept reporting that I had no support for openGL. I found this confusing becuase I was using the required Nvidia driver. I decided to update the driver and after I updated glxgears stopped working and winex still failed to compile. Also on nearly every program with a GUI reported this before starting.
Xlib: extension "GLX" missing on display ":0.0".
Xlib: extension "GLX" missing on display ":0.0".
kbuildsycoca running...
Xlib: extension "GLX" missing on display ":0.0".
Xlib: extension "GLX" missing on display ":0.0".
Have no idea what is going on please some on enlighten me.

do you have load glx in your xf86config file?

yes I do but still won't work here is the full config file

Ok, here is your problem in this secion of your config file:

Section "Device"
Identifier "device1"
VendorName "nVidia Corporation"
BoardName "NVIDIA GeForce2 DDR (generic)"
Driver "nv" <---- This needs to be "nvidia"... not "nv"
Option "DPMS"
EndSection

So it should look this this:

Section "Device"
Identifier "device1"
VendorName "nVidia Corporation"
BoardName "NVIDIA GeForce2 DDR (generic)"
Driver "nvidia"
Option "DPMS"
EndSection

Hope that helps ya. Oh, and you need to be root in order to edit it. So at your prompt just run vi, pico or do what i do, and just type:

kwrite xf86config-4

That'll bring it up in kwrite so you can use your mouse.

this maybe a stupid question but i noticed that you have "nv" as your driver, you did change this to "nvidia" right?

I changed it and it worked fine thanks

No problem.

About the winex compile:There are probably some libraries missing - just check for development packages for opengl.When you compile stuff on a binary distro there's always stuff like this popping up.
