skybox error c++

I'm creating a skybox with opengl everything compiles but when the program runs nothings changed but after looking through the build report I got this error

warning LNK4031: no subsystem specified; CONSOLE assumed

Any idea what this means? I'll supply any code if needed.

Project Properties, Linker, System, SubSystem.

Set it to Windows or Console as you prefer - Console will build as a Console application, it'll have a preallocated console when it starts. Windows will build as a non-console application, and require a WinMain instead of a main

It means the /SUBSYSTEM switch wasn't supplied to link.exe.

Here is the documentation on that switch: http://msdn.microsoft.com/en-us/library/fcc1zstk.aspx

If you're building a console application, you'll want to use /SUBSYSTEM:CONSOLE. If you're building a Windows application, you'll want to use /SUBSYSTEM:WINDOWS.

If you're using Visual Studio, you can modify the "SubSystem" setting under "Project -> Properties -> Configuration Properties -> Linker -> System".
