error: cannot convert ‘ns3::Node*’ to ‘ns3::NetDevice*’ in initialization

[Kamran Zahoor]

Hey all! tried to find for any similar thread addressing such problem but there was none. I'm trying to run a very simple simulation to stream the video from remote host to two UEs in LTE scenario. Attached in my code. I'm using the evalvid module. But, I'm encountering below mentioned problem while building the code. I'm unable to understand what this problem is. Please if anyone could help, it would be really a big favor.

In file included from ./ns3/attribute.h:25:0,
                 from ./ns3/csma-helper.h:25,
                 from ../scratch/Phase2.cc:24:
./ns3/ptr.h: In instantiation of ‘ns3::Ptr<T>::Ptr(const ns3::Ptr<U>&) [with U = ns3::Node; T = ns3::NetDevice]’:
../scratch/Phase2.cc:142:60:   required from here
./ns3/ptr.h:748:27: error: cannot convert ‘ns3::Node*’ to ‘ns3::NetDevice*’ in initialization
   : m_ptr (PeekPointer (o))

Many thanks in advance.

Humble Regards:

Hi Kamran,

please take a look into the ns-3 Doxygen documentation where you can see all classes, functions, their parameters, etc... what is the type of the parameter of the funcion you are calling in your simulation program. In this case you are passing to the function NodeContainer y Node when the funcion expects NetDeviceContainer and NetDevice. Thus, instead of passing ueNodes and enbNodes.Get(0) you should pass ueLteDevs and enbLteDevs.Get(0) (names according your simulation program).

Best regards,

Biljana

Thanks a bunch man. Error is removed and i've moved a bit forward. Once again thanks a lot.
