namespace jme {
template <class T> class Data {
    T data;
    int id;
    Data(T, const int);
    virtual ~Data();
    Data(const Data& other);
    Data& operator=(const Data& other);
    const int getId();
    const T& getData() {
        return data;

template <class T>
jme::Data<T>::Data() {}

template <class T>
jme::Data<T>::Data(T _data, const int _id) {
    this->data = _data;
    this->id = _id;
template <class T>
jme::Data<T>::~Data() {}

template <class T>
jme::Data<T>::Data(const Data& other) {
    //copy ctor
template <class T>
jme::Data<T>::operator=(const Data& rhs) {
    //if (this == &rhs) return *this; // handle self assignment
    //assignment operator
    this->T = rhs.T;
    //this->id =;
    return *this;
template <class T>
const int jme::Data<T>::getId() {
    return id;
int main(){
    jme::Data d;
    std::cout << "Hello world!" << std::endl;
    return 0;

The above program gives me this error message:

-------------- Build: Debug in data ---------------

Linking console executable: bin\Debug\list.exe
obj\Debug\main.o: In function `main':

What am I doing wrong?
