[ndnSIM] SetOldContentStore

[Asim ALHIMSYA]

Dear Colleagues,
When I run the following line of code:
ndnHelper.SetOldContentStore("ns3::ndn::cs::Lfu");

I get the following error message:

Waf: Entering directory `/home/asim/ndnSIM/ns-3/build'

information (./waf --run <program> --command-template="gdb --args %s
<args>").

How can I solve this problem?
Best regards
