Re: singleton question

I try to implement the Singleton for my Driver. The code piece:

/////////////////////////
MySingleton.h
/////////////////////////
template<class T> class CSingleton
{
public:
   static T* GetInstance();

protected:
   CSingleton();
   ~CSingleton();

private:
   CSingleton(CSingleton const&);
   CSingleton& operator=(CSingleton const&);
   static T* m_pInstance;
};

/////////////////////////
MySingleton.cpp
/////////////////////////

#include "StdAfx.h"
#include "MySingleton.h"

template<class T> T* CSingleton<T>::m_pInstance=NULL;
template<class T> T* CSingleton<T>::GetInstance()
{
   if(!m_pInstance)
   m_pInstance = new T;

   assert(m_pInstance !=NULL);

   return m_pInstance;
}

/////////////////////////
Driver.h
/////////////////////////

class CDriver
{
public:
   CDriver(void);
   ~CDriver(void);

   int GetData();

private:
   int m_nData;
};

/////////////////////////
Driver.cpp
/////////////////////////

#include "StdAfx.h"
#include "Driver.h"

CDriver::CDriver(void):
   m_nData(100)
{
}

CDriver::~CDriver(void)
{
}

int CDriver::GetData()
{
   return m_nData;
}

In my MFC dialog button routine:

void CMyDlg::OnBnClickedButtonSingleton()
{
   int n = 1;
   CDriver *pDriver = CSingleton<CDriver>::GetInstance();
   n = pDriver->GetData();
}

When I try to build it in studio 2010, I got link error:

MyDlg.obj : error LNK2019: unresolved external symbol "public: static
class CDriver * __cdecl CSingleton<class
CDriver>::GetInstance(void)" (?GetInstance@?
$CSingleton@VCDriver@@@@SAPAVCDriver@@XZ) referenced in function

OnBnClickedButtonSingleton@CBoostDlg@@QAEXXZ)
C:\Temp\Studio 2010\TestDlg\Debug\Test.exe : fatal error LNK1120: 1

What is wrong?
