I’ve got the latest version of my videocard driver for OpenGL 2.0, but I haven’t got the headers. I’m using VC 6.0++ with the <GL/gl.h> header version 1.1. Where can I download the new header for version 2.0?
Try to check your vendor website.
You need glext.h to program with greater than v1.1.
And, please read this FAQ section. You may get the idea how to program with extensions
Yes, I have the vendor specific OpenGL headers for Linux when I install the driver, but I do not know there is any for Windows. (Anyway, I never use them.)
download GLEE or GLEW extensions loading libraries.
