debug/libns3.so Undefined reference

[Hanene GABTENI]

Hi all,

I'm implementing new module in NS-3 I 'm inspired from AODV to set up the basic functionalities (it inherits from Ipv4RoutingProtocol)...
But I encoutered this ERROR:

debug/libns3.so: undefined reference to `vtable for ns3::RoutingProtocol'
debug/libns3.so: undefined reference to `typeinfo for ns3::RoutingProtocol'
collect2: ld returned 1 exit status

What aspect could I correct please.

Thanks and best regards,

Hi, I'm having the same problem. I'm trying to implement a new module, it used to work fine in ns-3.8, but I'm having issues trying to update the code.

Did you see : http://shieldroute.blogspot.se/2012/08/extending-ns3-with-your-module-and.html ? It suggests o solution, but he is using external libraries in his module.

This is my error:

./libns3-internet.so: undefined reference to `ns3::DispatchModule::Enqueue(ns3::Ptr<ns3::Packet>, ns3::Ipv4Header)'

Be sure to implement all virtual functions defined in the base class.

Make sure the base class destructor is virtual

Implement the destructor in your new class.

Mitch

Thanks a lot Mich!
I have implémented the destructor and this works OK now!

Best Regards!

Hi,
I am trying to compile the ndnSIM after define a pointer of one class from the energy model offered in ns3.
To clear it, e.g. If I define the pointer of "SimpleDeviceEnergyModel" anywhere in ndnSIM, see following code!
//----------------------------------------------------------
#include "ns3/simple-device-energy-model.h"
Class AnyClassInNdnSIM
{    public:
        Ptr<SimpleDeviceEnergyModel> sdem;
};
//----------------------------------------------------------

I am getting the following message:

./libns3-dev-ndnSIM-debug.so: undefined reference to `ns3::SimpleDeviceEnergyModel::SimpleDeviceEnergyModel()'
./libns3-dev-ndnSIM-debug.so: undefined reference to `ns3::SimpleDeviceEnergyModel::GetTypeId()'
collect2: ld returned 1 exit statusWaf: Leaving directory `/home/alhail/workspace/ndnSIM/ns-3/build'
Build failed...........

Could you give me any advise to solve this problem?
Regards
Mohamed
