Warum hab ich diese Linker fehler

  • ?

    Hallo,

    ich habe folgenden code unter VC++

    class BENTGINE_API DirectSound
{
	private:
		//variables
		static BOOL						m_bInitialized;		//Initialized
		static LPDIRECTSOUND8			m_pDSound;			//IDirectSound8 interface
		static LPDIRECTSOUNDBUFFER		m_pPrimaryBuffer;	//Primary Soundbuffer
		static LPDIRECTSOUND3DLISTENER8	m_pListener;		//Listener interface
		static mathVector3				m_vOldListenerPos;	//Time stamper of the SetListener methode

	public:
		//methods
		static Engine_Result Init(Config* pConfig, HWND hWindow=NULL,
									DWORD dwCoopLevel=DSSCL_PRIORITY, BOOL b3D=TRUE);
		static Engine_Result Exit();
		static Engine_Result SetListener(const mathVector3& vListenerPos, const mathVector3& yListenerYAxis,
											mathVector3& vListenerZAxis, const float fSpeedFactor=1.0f);

		//inline methods
		static inline BOOL						IsInitialized()				{return m_bInitialized;}
		static inline LPDIRECTSOUND8			GetDSound()					{return m_pDSound;}
		static inline LPDIRECTSOUNDBUFFER		GetPrimaryBuffer()			{return m_pPrimaryBuffer;}
		static inline LPDIRECTSOUND3DLISTENER8	GetListener()				{return m_pListener;}
		static inline mathVector3				GetOldListenerPosition()	{return m_vOldListenerPos;}	
};

    und erhalte folgende Fehlermeldungen

    Warum ist das so?

    Statische Membervariablen musst du zusätzlich zur Deklaration im Header noch in einer Quelltextdatei definieren:

    // .h
class C {
    static int i;
};

// .cpp
int C::i;
