I'm trying to make template for singleton. But I have problem
initialize the static pointer.

in .h file:
template<typename Type>
class Singleton
{
public:
static Type* theItem()
{
if(!item)
{
item = new Type;
}
return item;
}

private:
Singleton();
~Singleton();
Singleton(const Singleton&){}
static Type* item;

};

In cpp file:
template<typename Type>
Type* Singleton::item =0;
doesn't work.
How can I initialize static template type?

Try this small,simple and smart Singleton class

template<typename T>
class Singleton
{
Singleton();
Singleton(const Singleton<T>&);
public:
static T* instance()
{
static T holder;
return &holder;
}
};
