[ndnSIM] (no subject)

[Xinyu Ma]

Well, are you using the newest version of ndnSim?
It's expected to find that there are three files:
ns-3/src/ndnSIM/examples/ndn-simple-with-content-freshness.cpp
ns-3/src/ndnSIM/examples/ndn-simple-with-content-freshness/one-interest-requester.hpp
ns-3/src/ndnSIM/examples/ndn-simple-with-content-freshness/one-interest-requester.cpp

And it's expected to  see this command:
NS_LOG_COMPONENT_DEFINE("OneInterestRequester");
at the 31th line of one-interest-requester.cpp.

If not, please update to newest ndnSim 2.5.
