When creating my C++ program, I'm getting the error message
undefined reference to 'vtable...
What is the reason for this issue? How would I fix it?
My code:
class CGameModule : public CDasherModule {
public:
CGameModule(Dasher::CEventHandler pEventHandler, CSettingsStore *pSettingsStore, CDasherInterfaceBase *pInterface, ModuleID_t iID, const char *szName)
: CDasherModule(pEventHandler, pSettingsStore, iID, 0, szName)
{
g_pLogger->Log("Inside game module constructor");
m_pInterface = pInterface;
}
virtual ~CGameModule() {};
std::string GetTypedTarget();
std::string GetUntypedTarget();
bool DecorateView(CDasherView *pView) {
//g_pLogger->Log("Decorating the view");
return false;
}
void SetDasherModel(CDasherModel *pModel) { m_pModel = pModel; }
virtual void HandleEvent(Dasher::CEvent *pEvent);
private:
CDasherNode *pLastTypedNode;
CDasherNode *pNextTargetNode;
std::string m_sTargetString;
size_t m_stCurrentStringPos;
CDasherModel *m_pModel;
CDasherInterfaceBase *m_pInterface;
};
Inherits from...
*class CDasherModule;
typedef std::vector<CDasherModule*>::size_type ModuleID_t;
/// \ingroup Core
/// @{
class CDasherModule : public Dasher::CDasherComponent {
public:
CDasherModule(Dasher::CEventHandler * pEventHandler, CSettingsStore * pSettingsStore, ModuleID_t iID, int iType, const char *szName);
virtual ModuleID_t GetID();
virtual void SetID(ModuleID_t);
virtual int GetType();
virtual const char *GetName();
virtual bool GetSettings(SModuleSettings pSettings, int *iCount) {
return false;
};
private:
ModuleID_t m_iID;
int m_iType;
const char *m_szName;
};
