Using mingw to cross-compile an opengl application for windows

Question

heya, I am running linux (ubuntu),

I have problems with this. I tried loading glut32.dll and pasting it into the mingw lib / directory, and setting the appropriate headers in include /, however, although compilation is fine - the linker has a serious problem finding characters.

How can i do this? how can i create an opengl application for windows using mingw?

thanks,
