Why would including the GLUT header fix the missing symbol? Including a header is a compile time process, and the missing symbol is a linker error.

You have created the wrong type of executable project. There are two common types; Application and Console Application. An Application requires a WinMain() function, and a Console Application requires a main() function. Dependeing on which of these two functions you have, you have to create the right type of project.

No, the problem is that you don’t know your compiler enough. The settings of your project does not match the code.
