[ndnSIM] problem running with visualizer

[Swetha]

Hi

I have problem running ndn-simple with visualizer. I am getting response 
as below.


root at swetha-Ubuntu:~/ndnSIM/ns-3# ./waf --run=ndn-simple --vis
Waf: Entering directory `/home/swetha/ndnSIM/ns-3/build'

line 70, in <module>
     if ns_mesh_loaded:
NameError: name 'ns_mesh_loaded' is not defined

Kindly suggest how to proceed. NS_LOG output is working fine.

Thanks,
