[ns] Problem to link my model ... No Error in compilation ...

Hi all,
I terminate to write my code for Optical Buffer ....
I compiled and when link go out this message :

Really i have a OptQueueHandler object in Optical Class definition definition that
is a pointer to my object Optical....
we can see the definition class .... :


class OptQueueHandler : public Handler {
public:
	inline OptQueueHandler(Optical& q) : queue_(q) {}
	void handle(Event*);
private:
	Optical& queue_;
};

This object substitute the QueueHandler object in my case.

class Optical : public Queue {
public:
	Optical(); // Call the constructor in Optical.cc
	void OutPacket();
		
protected:
	int command(int argc, const char*const* argv);
	int Optlen_;
	void recv(Packet*, Handler*);
	void enque(Packet *);
        int enque(Packet *p,int i);
	Packet* deque();
	OptQueueHandler qh_;
	OpticalPacketQ *q_;
	OpticalPacketQ *pq_;
	int lines;
	double delay_line[MAXLINE];
	OpticalTimer delaySend_;
};

Have somebody a razon o idea for this error ??

Thanks in advanced ...
