wish helps you You never define how an Employee should be outputed.
Just implement the following function and you will be good!
code :
std::ostream&
operator<<(std::ostream& out, const Employee& e)
{
    /* Print an Employee. */
}

fixed the issue. Will look into that further If you want class A to befriend the function template foo(), you need to use:
code :
template <E> friend int foo();
friend int foo<a1>();

With these it helps I have a data container which has following requirements: , I know that it's not a perfect solution, but you can try to replace
code :
typedef impl_storage_container<data_c<int, impl_storage_container> > c_storage_container;
typedef impl_storage_container<data_c<int, storage_container_impl> > c_storage_container;

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 , I have template class with a nested template class like this , Try this:
code :
template<typename K> 
std::pair<bool, typename Tree23<K>::template Node<K> *> Tree23<K>::Search(K key)
//              ^^^^^^^^            ^^^^^^^^
{
    // make sure tree has at least one element
    if (root == 0) {
          return std::make_pair(false, 0);

    } else {
          return Locate(key, root);
    }
}

will help you After some investigation, I have the answer to my own question and post it right here:
In fact, I misunderstand what 'explicit' keyword means. See my other question HERE.
