[ndnSIM] [EXT] SetOldContentStore

[Asim ALHIMSYA]

Hi Junxiao,
I executed the following code:

  ndn::StackHelper ndnHelper;
  ndnHelper.setCsSize(1000);
  *ndnHelper.setPolicy ("nfd::cs::lfu");*
  ndnHelper.InstallAll();

but the following error occurred:

Waf: Entering directory `/home/asim/ndnSIM/ns-3/build'
Waf: Leaving directory `/home/asim/ndnSIM/ns-3/build'
Build commands will be stored in build/compile_commands.json
'build' finished successfully (1.048s)
*msg="Cache replacement policy nfd::cs::lfu not found",
file=../src/ndnSIM/helper/ndn-stack-helper.cpp, line=168*
*terminate called without an active exception*
Command

terminated with signal SIGIOT. Run it under a debugger to get more
information (./waf --run <program> --command-template="gdb --args %s
<args>").

How can I solve this problem so I can use LFU cache replacement policy?
