Linking...
LIBCD.lib(crt0.obj) : error LNK2001: unresolved external symbol _main
Debug/NullEngine.exe : fatal error LNK1120: 1 unresolved externals
Error executing link.exe.

your compiler was expecting to find a function "main", and didn''t.

Why does it want a main()??? I have a WinMain, isn''t that the same thing???

No.
It most likely wants a main() because your project is a Win32 Console App, instead of a ''normal'' Win32 app.

Yes. it''s in MSDN. If you have MSVC and the MSDN Library installed, highlight the error code in the output pane and hit F1. otherwise, you''ll have to search MSDN Library Online.

Thanks to Kylotan for the idea!

Ok then, where in a project settings is the ability to tell the compiler it is a win32 application and not a console application??

(I''m using Micro$oft visual c++)

I think its easiest to just create a new Win32 project than add all of your files.

You know, main() is normal for C++, WinMain() isn''t.
When you choose to create a Win32 app, my guess is that VC++ links to a main() function that basically calls WinMain()
