Problem with multiple class files, main, and pointers.

[Failbound]

Okay, I have a small declaration/reference problem in my main.

  int main(int argc, char *argv[])
{
        Initialize mainkey;
        mainkey.Initial();


        Overworld key;
        key.LoadBG();
        key.DisplayBG();
    }

This is my current main, just to check if each function within each class works.
The problem is, the function DisplayBG(); is declared in my class file as
SDL_Texture* DisplayBG ();

How do I reference that function properly in my main? At the moment I get an undefined reference error.

If DisplayBG() is a public declared method of Overworld then everything should be fine. Please post Overworld class specification.

I'm guessing you haven't included the definitions of either Initialize or Overworld.
