    Getting Errors when calling pModel (Model Loading again)

    Okay, so I declared the pointer extern in MS3D.H and wrote it in the .cpp file the way its spose to be, I add the header file MS3D.H to my main cpp file, the only problem is, when i call the pointer it does this.


    I call pModel like this

    Code:
    	pModel = new MS3DModel();
    	if ( pModel->LoadModelData( "data/model.ms3d" ) == false )
    	{
    		MessageBox( NULL, "Couldn't load the model data/model.ms3d", "Error", MB_OK | MB_ICONERROR );
    		return 0;									// If Model Didn't Load, Quit
    	}
    Code:
    --------------------Configuration: NeHeGL - Win32 Debug--------------------
    Compiling...
    Example.cpp
    C:\Documents and Settings\colemanjon\Desktop\RenderEngine\Example.cpp(27) : error C2501: 'pModel' : missing storage-class or type specifiers

            This conversion requires a reinterpret_cast, a C-style cast or function-style cast

    is pModel declared as a MS3DModel?

    Sorry for the stupid question but I can't figure out what it could be.

    I declare it like this

    Code:
    MS3DModel *pModel = NULL;
    and call it like the first post

    Why do you have that bit of code just floating in the global namespace like that? Put it in a function where it belongs.

    yeah yeah, i know, im just putting it there so i know its not hiding under anything and missing the declaration, its being a pain, i'd normally have it in the winmain section..

    No, I mean that's why you are getting the errors.

    Well I'd have to see the whole project to really say, but yes it should work correctly if it's in winmain and you use extern correctly.

    i fixed it, no floating declarations of the Mode class, only in a cpp file where I need it, then calling it in winmain
