c++ - container for derived template classes -

i have next classes:

template <typename t> class packetmember { public: packetmember() { } // non-virtual fellow member functions }; template <typename t> class normalmember : packetmember<t> { public: }; template <typename t> class checksummember : packetmember<t> { public: };

i have std::vector container containing std::unique_ptr or std::shared_ptr. created 1 this:

typedef std::unique_ptr<packetmember<unsigned char> > prt; std::vector<prt> v; v.push_back(prt(new normalmember<unsigned char>(header)));

but compiler complains packetmember<unsigned char> beingness inaccessible base of operations of normalmember<unsigned char>. i've seen people suggesting on website utilize poiter / smart-pointer base of operations class , create point derived classes. doing wrong here?
