Is there a opengl4.lib ?

Is there a opengl4.lib for win32 ?

where can i get it?

what’s wrong with the opengl.dll you graphics card vendor provides with their drivers?
Have you created an OpenGL 4 context with it or even attempted to?
The name of the DLL has nothing to do with the version of OpenGL supported by the hardware.

There is no opengl4.lib. The only application that uses .lib files is Microsoft Visual C++. It comes with opengl32.lib.
It provides the functions available in the system file opengl32.dll

If you want to access higher level functions…you read the Wiki

and the FAQ
