what is the correct way to compile a class that uses templates. i keep getting an error msg on the linking step. can some one help?

"Stack.h"
Code:
 
#pragmaonce
 
template <class xtype>
struct node
{
	 xtype info;
	 node * next;
};
 
template<class xtype>
class Stack
{
private:
	 node<xtype> * top;
public:
	 Stack(void);
	 ~Stack(void);
	 void Push(xtype);
	 void Pop(xtype&);
	 bool Isfull(void);
	 bool Isempty(void);
};
 
"Stack.cpp"
Code:
 
#include"Stack.h"
 
template <class xtype> 
Stack<xtype>::Stack(void)
{
	 top = NULL;
}
 
template <class xtype> 
Stack<xtype>::~Stack(void)
{
	 node<xtype>* q;
	 while(top != NULL)
	 {
		  q = top;
		  top = top->next;
		  delete q;
	 }
}
 
template <class xtype>
void Stack<xtype>::Push(xtype item)
{
	 node<xtype>* p;
	 p = new node<xtype>;
	 p->next = top;
	 p->info = item;
	 top = p;
}
 
template <class xtype>
void Stack<xtype>::Pop(xtype& item)
{
	 if( !Isempty() ) 
	 {
		  item = top->info;
		  node<xtype>* p;
		  p = top;
		  top = top->next;
		  delete p;
	 }
 
}
 
template <class xtype>
bool Stack<xtype>::Isfull()
{
	 node<xtype>* freestore;
	 freestore = new node<xtype>;
 
	 if(freestore == NULL)
		  return true;
	 else
	 {
		  delete freestore;
		  return false;
	 }
 
}
 
template <class xtype>
bool Stack<xtype>::Isempty()
{
	 return (top == NULL);
}
 
"main.cpp"
Code:
#include"Stack.h"
using namespace std;
int main()
{
	 Stack<int> q;
return 0;
 
}
