c++孤子&&A template declaration cannot appear at block scope

 抄写了一个C++的孤子实现，代码来自与arcemu项目。
Singleton.h

#ifndef __SINGLETON_H__
#define __SINGLETON_H__
#include<assert.h>
#define initialiseSingleton( type )\
template <> type* Singleton<type>::mSingleton_=0
#define createSingleton( type )\
initialiseSingleton( type );\
type the##type

template<class T>
class Singleton
{
public:
    Singleton(){
    assert(this->mSingleton_==0);
    this->mSingleton_=static_cast<T*>(this);
    }
    virtual ~Singleton()
    {
        this->mSingleton_=0;
    }
  static T &getSingleton(){
      assert(mSingleton_);
      return *mSingleton_;
      }
    static T* getSingletonptr()
    {
        assert(mSingleton_);
        return mSingleton_;
    }
protected:
    static T *mSingleton_;
};

#endif // __SINGLETON_H__

test.cpp

#include<iostream>
#include<stdio.h>
#include<string.h>
#include"Singleton.h"
class TestSingleton:public Singleton<TestSingleton>
{
public:
    TestSingleton(){}
    ~TestSingleton(){}
    void print(char *s,int len)
    {
        printf("%s %d\n",s,len);
    }
};
createSingleton(TestSingleton);
int main()
{
    char s[]="hello fuck";
    TestSingleton::getSingleton().print(s,strlen(s));
}

 遇见错误的代码是这样的，提示A template declaration cannot appear at block scope。原因就是宏定义里面涉及到类的静态成员的初始化。You cannot define template inside a function, and main is a function。

int main()
{
    char s[]="hello fuck";
    createSingleton(TestSingleton);//wrong use
    TestSingleton::getSingleton().print(s,strlen(s));
}
