[ns] Problem in defining of a new timer

["Haruki" <haruki@katto.comm.waseda.ac.jp>]

Hi there.

I tried to create a new timer as follows :

 class MyConnector : public Connector

        ...............
 };
 class MyTimer : public TimerHandler {
        public:
            MyTimer(MyConnector *a) : TimerHandler() { a_ = a; }
        protected:
            void expire(Event *e);
            MyConnector *a_;
  }

and when linking gcc(g++) , I got error message as "undefined reference to
virtual table".
Could you please give me the solution of this problem or info?
Thanks.

rgds,
Haruki
