How to solve undefined references, is the library not imported, or other problems - win32gui

Question

I'm trying to use Win32 GUI project on a project, but when I compile it, I get a lot of undefined reference errors.

Answer 1

You includes have a forward slash in the naming. Maybe you wanted #include "path/name".

Answer 2

I believe you would have solved it by now; in case not then you can try providing correct library path. Use command line options -L for path to library folder and -l for library name while compiling/linking.
An online lookup for OpenGL suggests the library file names may be any or all from these: opengl32.a or opengl32.lib, glu32.a or glu32.lib, freeglut.a or freeglut.lib (choose .a if you are building on Linux or .lib on Windows).
