class is not a template

[hadoque]

I'm making a simple stack template and the compiler (g++) is complaining about the class not being a template:

hadoque@meitner:~/skola/c$ g++ -o driver driver.cpp stackTemplate.h
driver.cpp: In function ‘int main()’:
driver.cpp:9: error: ‘stackTemplate’ is not a template

class implementation:

#include <iostream>

using namespace std;

template <class T>
class stackTemplate
{
public:
    stackTemplate(int);
    ~stackTemplate();

private:
    T *stackArray;
    int stackSize;
    int top;
};

template <class T>
stackTemplate<T>::stackTemplate(int stackSize)
{
    top = -1;
    this->stackSize = stackSize;
    stackArray = new T[stackSize];
}


template <class T>
stackTemplate<T>::~stackTemplate()
{
  delete [] stackArray;
  stackArray = NULL;
}

driver:

#include "stackTemplate.h"

int main()
{

  stackTemplate<int> apa(10); 


 return 0;
}

Visual C++ does not produce any error with this code. Any ideas?
