Circular Dependencies / Incomplete Types

Question

In C++, I have a problem with circular dependencies / incomplete types. The situation is as follows:

Stuffcollection.h

#include \"Spritesheet.h\";
cl         


        

Answer 1

You should include Spritesheet.h in Stuffcollection.cpp
Just use forward declaration in the header file not the cpp file, that solves the circular dependency of the header file. The source file has no circular dependency actually.

Stuffcollection.cpp needs to know the complete layout of class Spritesheet(because you dereference it), So you need to include the header which defines the class Spritesheet in that file.

From your previous Q here, I believe that class Stuffcollection is used in the class declaration of Spritesheet header file and hence the above proposed solution.
