It doesn't link because of [templ.expl.spec]:

   An  explicit specialization of a static data member of a template is a
   definition if the declaration includes an initializer;  otherwise,  it
   is  a  declaration.  [Note: there is no syntax for the definition of a
   static data member of a template that requires default initialization.
   template<> X Q<int>::x;
   This  is a declaration regardless of whether X can be default initial-
   ized (_dcl.init_).  ]

You must provide the initializer, e.g.

template<> int ObjectPool<char>::mutex = 0;
