c++ - Using Template Member data

I was trying to use a template based class as a member of another class. This other class will decide based on its data member value what is the data type that the template based member should use. To this end I used bit of polymorphism to decide on run time the instantiation.

class Base
{
public:
    virtual void print() = 0;

};

template 
class templateDynamic : public Base
{
public:
    templateDynamic();
    ~templateDynamic();
    void print();
};


    template 
templateDynamic::templateDynamic()
{
}

template 
templateDynamic::~templateDynamic()
{
}


template 
void templateDynamic::print()
{

}

class Holder
{
private:

    Base * m_ABC;
public:
    Holder(int a);  
    void print();
};

void Holder::print()
{
    m_ABC->print();
}


Holder::Holder(int a)
{
    if(a == 1)
      m_ABC = new templateDynamic();
    else
      m_ABC = new templateDynamic();
}

int main()

{
    Holder aHolder(1);
    aHolder.print();
    Holder aHolder2(2);
    aHolder.print();
}

Print function will then print based on the type of T is it an int or float.
I am getting a linker error at this point.

error LNK2019: unresolved external symbol "public: __thiscall
templateDynamic::templateDynamic(void)"

__thiscall Holder::Holder(void)" (??0Holder@@QAE@XZ)
