template class with Non-type template Parameter member function

I am trying to define a specialization of a template class which contains a Non-type template Parameter member function. And I get the following error:

error: too few template-parameter-lists

Here's a sample class that describes the problem in brief,
// file.h
template <typename T>
class ClassA {
  T Setup();
  template <int K> static void Execute();
};

//file.cc
void ClassA<int>::Execute<2>() { //Do stuff    }

I believe this is more of a syntax issue than a design issue, any clues? Thanks

You forgot to tell the compiler that you're specializing a template method of a template class:

template <>
template <>
void ClassA<int>::Execute<2>()
{
    //Do stuff
}

Even if you fully specialize a template, you still need template<>:

template<> template<> void ClassA<int>::Execute<2>() { //Do stuff    }
