Warum hab ich diese Linker fehler

[TheGamer]

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?

Du hast vergessen deine ganzen statischen Variablen auch noch irgendwo zu definieren.

Im Cpp File sollte also noch etwas in der Art von

LPDIRECTSOUND8 DirectSound::m_pDSound = NULL;

usw.

stehen
