Enum in header files

I have enum declared in a header file called "sm.h"

enum GameStates
{
  STATE_NULL = 0,
  STATE_INTRO,
  STATE_TITLE,
  STATE_MAIN,
  STATE_EXIT
};

All it does is list the possible game states

However in the following line in "base.cpp":

stateID = STATE_INTRO;

The compiler says "STATE_INTRO was not declared in this scope". I have no idea what I am doing wrong. I know that I have included the header file right and I can go to its deceleration from the .cpp file. So why am I getting this error.

stateID = STATE_INTRO;

Is used in:

bool baseFunctions::load_rc()
{
 stateID = STATE_INTRO;

 currentState = new Intro();

 return true;
}

which defines a class function in a header file.

There are no global conflicts because it is the only enum in the whole program

From your link to your files, you have the following in both sm.h and base.h

#ifndef BASE_H_INCLUDED
#define BASE_H_INCLUDED

Change the one in sm.h to something like

#ifndef SM_H_INCLUDED
#define SM_H_INCLUDED

and I expect you'll be fine.

As it is, base.cpp loads base.h, then when it gets to sm.h the #ifndef is false, so it excludes everything in sm.h.

Most likely is that you aren't including "sm.h" in base.cpp
