c++ - Template Classes Multiple-File Project - How to?

I'm working on a project where I need my "stack" to save data. But I don't want to code a different version for every single filetype (and I don't want to use vectors).

So I'm trying to use a template class, and this is my code:

StructStack.h

#ifndef STRUCTSTACK_H_

#define STRUCTSTACK_H_

template  class StructStack {
    StructStack();
    ~StructStack();
    struct Element {
        Element *pointer;
        AnyType value;
    };
    Element *pointerToLastElement;

    int stackSize;
    int pop();
    void push(int value);
    int size();
};

#endif

StructStack.cpp

#include "stdafx.h"
#include "StructStack.h"
#include 
using namespace std;


template  void StructStack::StructStack() {
    //code
}


template  void StructStack::~StructStack() {
    //code
}

template  AnyType StructStack::pop() {
    //code
}

template  void StructStack::push(AnyType value){

    //code
}

template  AnyType StructStack::size() {
    //code
}

If I try to compile these two files, I'm getting a bunch of compiling errors. I read online that it is kind of hard to create a template class in a multiple-file project.

So how can this be done?

Answer

You can solve this by putting all the definitions (code you currently have in StructStack.cpp) in StructStack.h, and removing the former. The compiler needs to have access to the implementation code so it can instantiate the class template as needed.
