help you fix your problem The type of names is char const*[2]; after conversion to a pointer, it becomes char const**, not char*. You can't call the non-template function, because there is no conversion from char const** to char*.
Also, of course, the special version shouldn't be a template, since it only works for the type char const**:
code :
char const*
maxn( char const** ptr, int n )
{
    //  ...
}

around this issue You should change the order of your template parameters for the do_work<>() function template, or your instantiation will indeed be incorrect:
code :
//   template<typename OtherFoo, unsigned X> // This order is not appropriate.
                                             // Let template parameters that
                                             // cannot be deduced come first...
     template<unsigned X, typename OtherFoo>
     //       ^^^^^^^^^^  ^^^^^^^^^^^^^^^^^
     //       THIS FIRST      THEN THIS
     void do_work(const OtherFoo* __restrict, float, Foo* __restrict) const
     {
     }
foo->template do_work<123>(foo_2.get(), x, &out);

I think the issue was by ths following , SetOfCells uses cellParent - which either does not define template T get(int cellIndex) or it defines it but it is not overridden in the cell class.
Note it is not possible to do what you are trying to do: you cannot override a template member function in C++.
code :
template <class T>
class SetOfCells
{
    ....
    T get(int cellIndex)
    {
       return cellArray[cellIndex]->get();
    }
    ....
private:
    cell<T>**  cellArray;
};

fixed the issue. Will look into that further The compiler doesn't know that ref.foo is a template, so you need to tell it:
code :
ref.foo<1>();
//change to
ref.template foo<1>();

may help you . Here f is a dependent name (it depends on T), so you need to disambiguate the fact that it is a template :
code :
Foo<T>::template f<U>();
