c++ - Function pointer type not recognized inside template class -

i have typedef define function pointer.

typedef script*(*createobjectfn)(tixmlelement* node); 

i've created generic container purpose acts map. it's called dictionary, i've created dictionary of createobjectfn inside class this:

class scriptbank {  public:   ~scriptbank();     static dictionary<createobjectfn>& getinstance()     {           static dictionary<createobjectfn>& registry = m_registry;        return registry;     }  private:     static dictionary<createobjectfn> m_registry;     scriptbank(); }; 

i have various type of script in dictionary want put inside function of derived script.

now template class:

template <class t> class register { public:     register()     {         scriptbank::getinstance().insert("some string", t::create);     }     ~register()     {     } }; 

inside derived script have like:

    static script* create(tixmlelement* node); static register<doorchstatescript> m_registry; 

my purpose insert function pointer @ compilation time, compiler seems not recognize right type. in register class got error: cannot convert parameter 2 'script *(tixmlelement *)' 'createobjectfn *'

any ideas?
