Error C2061 In visual studio

Question

I try to reference a struct from another class in my code and it gives me an error, saying I have a syntax problem.

#pragma once

#include "Definitions.h"

#include "GV.h"
#include "UI.h"
#include "Tile.h"
#include "Item.h"

class Figure {
public:
    //Figure index
    struct FIGURE_TYPE {
        //Where to crop the image from
        SDL_Rect crop;
        int x;
        int y;
    };

    //The game figure
    FIGURE_TYPE figure_index[FIGURE_COUNT];

    //The figure array
    int figure_array[MAP_HEIGHT / 64][MAP_WIDTH / 64];

    //Functions
    Figure ( void );
    bool draw_figures ( SDL_Surface* screen, SDL_Surface* figures, SDL_Rect camera, Figure::FIGURE_TYPE figure_spec[FIGURE_COUNT] );
};

That's the struct in Figure.h,

#pragma once

#include "Definitions.h"

#include "GV.h"
#include "Tile.h"
#include "Item.h"
#include "Figure.h"

class UI {
public:
    UI ( void );
    void set_camera ( SDL_Rect& camera, Figure::FIGURE_TYPE figure_spec[FIGURE_COUNT] );
    bool draw_map ( SDL_Surface* screen, SDL_Rect& camera, SDL_Surface* tiles, SDL_Surface* figures, Figure::FIGURE_TYPE figure_spec[FIGURE_COUNT] );
    bool draw_status ( void );
};

And that is where I reference it, from another header file called UI.h. I know there is a problem with referencing structures, I just don't know how to fix it. Simple problem, any one wanna help?

The problem is not that Figure Type is declared outside of Figure.h, or that it is private as opposed to public.

Answer 1

You have a circular dependency: UI.h depends on Figure.h, and Figure.h depends on UI.h. You need to break the circular dependency by removing the #include of one file in the other. In this case, since I don't see anything in Figure.h using anything in UI.h, you should just remove the #include "UI.h" from Figure.h and be all set.
