[ndnSIM] Help ! Assert in TypeId::LookupByName: error. Could not find the class

[vivek pandya]

I am try to create a custom application for ndnSIM. I am following
http://ndnsim.net/2.1/applications.html#custom-applications.
I have put all my source .cpp and .hpp files in*
ndnSIM/ns-3/src/sndSIM/apps*  but when I try to run it I am getting
following error.

assert failed. cond="uid != 0", msg="Assert in TypeId::LookupByName:
CustomConsumer not found", file=../src/core/model/type-id.cc, line=755
terminate called without an active exception

This error is similar to
