I recently installed the Linux x64 (AMD64/EM64T) Display Driver Version 319.17 on Open Suse 12.1 and the installer didn't install the OpenGL header files gl.h, glext.h glx.h, glxext.h.
I also looked for them at the OpenGL webpage without success. Where can I find these files or is there any installer option for the header files?

Thanks for your help!
