You seem to be using the wrong type of project. If you are using GLUT then (I think) that you need to have a Win32 console application. If you are not using GLUT then a Win32 application is the type of project that you need.

Good luck

Of course doing a clean build didn't fix it. You created a console app, and you have NO MAIN FUNCTION!

Say it with me...

Win32 Console app = main() entry point
Win32 Application = WinMain() entry point

Any questions?

You can also force entry point (I prefer main(), since it's more portable than WinMain), regardless if you're building a Console or Windows app.

The command line flag for using main() is:


There is probably a similar setting accessible from the IDE too.

Now you can use main() - always (for building GLUT Windows applications too)!

The thing is, it is already a WinMain() function. Anyone got any other suggestions???

It may well be a WinMain() function - but is that in a project type of "Win32 console Application" or "Win32 Application"

The "console" part is important!

Look at what Latrans said!

Stupid, Stupid, Stupid. (Bashes Head Against Desk)!!!

I started a new project (Win32 App), added a C++ source file, copied the code and presto. It worked.
