'defaultHealthCalc' is not a member of 'GameStuff'

[Observer]

Hello!

Why I received this message:

GameCharacter.h:13: error: 'defaultHealthCalc' is not a member of 'GameStuff'
explicit GameCharacter( std::string name, HealthCalcFunc hcf = GameStuff::defaultHealthCalc )

GameCharacter.h

#ifndef GAMECHARACTER_H
#define GAMECHARACTER_H

#include <string>
#include "functionsForHealthCalc.h"

namespace GameStuff {

    class GameCharacter {
    public:
        typedef int (*HealthCalcFunc)(const GameCharacter&);

        explicit GameCharacter( std::string name, HealthCalcFunc hcf = GameStuff::defaultHealthCalc )
        {
        }

    };
}

#endif // GAMECHARACTER_H 

functionsForHealthCalc.h

#ifndef FUNCTIONS_FOR_HEALTHCALC_H
#define FUNCTIONS_FOR_HEALTHCALC_H

#include "GameCharacter.h"

namespace GameStuff {

    class GameCharacter;

    int defaultHealthCalc( const GameCharacter& gc );
}

#endif // FUNCTIONS_FOR_HEALTHCALC_H 

functionsForHealthCalc.cpp

namespace GameStuff {

    int defaultHealthCalc( const GameCharacter& gc ) {
        return 1;
    }
}

main.cpp

#include <iostream>

int main() {

    return 0;
}

There are all my files. Please, help me!

#include "functionsForHealthCalc.h" needs to be in your main.cpp

Sorry - you need to have #include "functionsForHealthCalc.h" in your gameCharacter files.

Thanks! I just removed #include "GameCharacter.h" from functionsForHealthCalc.h
