could anyone please tell me how to use nehe''s basecode with dev c++?

Just create a new project(win32 of course), add the NeHe .cpp en .h files

and somewhere in the menus you should find something like project settings and in that dialog box under link you type :
-lopengl32 -lglu32 -lglaux to link the opengl librarys.
Compile and it should work
