tearing opengl

[codist]

I have an OpenGL application. When I try to draw a multi-color triangle, it tears.
How do I fix that? A timer would work where it calls the draw function 60 times a second, but how do you do that?

OpenGL has a function to sync the frame buffer with the vertical refresh to prevent tearing.

What function? Can you give some examples.

It gives me an error:

undefined reference to 'wglSwapIntervalEXT(int)@4'

[codist]

Is there another way of doing it?

Did you link the proper libraries?

[codist]

What library? I have linked gdi32, opengl32, glu32, user32

I don't think wglSwapIntervalEXT is supported by my hardware. Is there another way of doing this?
