How to declare a class template taking an instance of another template as parameter ?

Hi guys,

I am trying to build a class template who is supposed to take an instance of another class template as parameter. Here's the idea :

Rough idea of the call in main():

const aClassTemplate<type> templateObjectName;
otherClassTemplate<type,> secondTemplateObjectName;

My .hpp declares the template with this line :

template <typename Type, const aClassTemplate<Type>& NameOfInstance>

The problem is that this doesn't seem to work. Even when compiling i get a 'linkage error', does anyone know how to do this properly ?

As asked, compliant code of actual class (content doesn't matter) :

template <typename Type, const ConPol<Type>& Div>
class ModPol : public Pol<Type>, public VectFix<Type, Div.size()>{
private:
    //
    
protected:
    //
    
public:
    // constructors & destructor
    ModPol();                                  
    virtual ~ModPol();
    
};

Call in main():

const ConPol<int> poly;
ModPol<int, &poly> modpoly;

Actual error:

error: non-type template argument refers to object 'poly'
that does not have linkage
