Bonjour,

Je cherche a créer une classe singleton.
J'ai suivi le tuto mais je rencontre une erreur:

Voici le .h

Code :

Sélectionner tout - Visualiser dans une fenêtre à part

class Ressources_Manager {
public:
	static Ressources_Manager& Instance();
 
private:
	Ressources_Manager& operator= (const Ressources_Manager&){}
	Ressources_Manager (const Ressources_Manager&){}
 
	static Ressources_Manager&  m_instance;
	Ressources_Manager();
	virtual ~Ressources_Manager();
 
	sf::Texture H_Sp_Prairie;
	sf::Image   Img_H_Prairie;
 
	void Load_Textures();
	void Load_Images();
};

et le .cpp

Code :

Ressources_Manager Ressources_Manager::m_instance=Ressources_Manager();
 
		Ressources_Manager::Ressources_Manager() {
 
			Load_Images();
			Load_Textures();
		}
 
		Ressources_Manager::~Ressources_Manager() {
 
		}
 
		Ressources_Manager& Ressources_Manager::Instance()
		{
		    return m_instance;
		}
 
		void Ressources_Manager::Load_Images()
		{
			Img_H_Prairie.loadFromFile("Image/HexaTestSize.bmp");
			Img_H_Prairie.createMaskFromColor(sf::Color(255,255,255));
		}
 
		void Ressources_Manager::Load_Textures()
		{
			H_Sp_Prairie.loadFromImage(Img_H_Prairie);
		}

et l'erreur affichée est:

Une idée?

Merci

Mea culpa,

Dans mon.h :
static Ressources_Manager& m_instance;

au lieu de:
static Ressources_Manager m_instance;
