Hi John
The scenario template, as of commit 2b5b6f55f04982273e62127082a19459ec68ff43
<https://github.com/named-data-ndnSIM/scenario-template/tree/2b5b6f55f04982273e62127082a19459ec68ff43>
,
is compatible with ndnSIM 2.1, and may or may not work with other versions.
However, I do not see why the scenario template is looking for ndn-cxx,
because there's no "ndn-cxx" token in its wscript.
Yours, Junxiao
