[ndnSIM] How to add LTE module into ndnsim-car2car？

[Quan Wei]

Dear Alex,

    We have tried to add Lte interface into the Car node based on the
ndnsim-car2car
sources.

    In detail, we modified the car-relay.cc by adding the head files:
-------------------------------------------------------
       #include "ns3/lte-module.h"
       #include "ns3/lte-helper.h"
-------------------------------------------------------

     and the create LTE object codes:
------------------------------------------------------------------------------------------
       Ptr<LteHelper> lteHelper = CreateObject<LteHelper> ();
       NetDeviceContainer ueDevs = lteHelper->InstallUeDevice (nodes);.
------------------------------------------------------------------------------------------

   When we conduct the "./waf", it shows the following errors:
----------------------------------------------------------------------------------------------

collect2: error: ld returned 1 exit status
Waf: Leaving directory `/home/cheewii/ndnSIM/ndnSIM-nom-rapid-car2car/build'
--------------------------------------------------------------------------------

It seems that the compiling is finished but there are some problems in the
linking process with lte module, is it right?

How can we reslove this problem?

Thank you very much.
