_glutKeyboardUpFunc@4

In can compile my code, but when I launch it I have this message :
_glutKeyboardUpFunc@4 not found in GLUT32.DLL

The function glutKeyboardUpFunc is in my DLL.
I tryed to add : #define GLUT_API_VERSION 4
but that doesn’t work too.

I found my mistake!

I downloaded the last verion of GLUT 3.7 : http://www.opengl.org/developers/documentation/glut/index.html?GLUT#windows

And that work very well.
