[ndnSIM] 回复: Re: question for topology

[Alex Afanasyev]

Hmm... I suspect it is an old feature/bug with linking on Linux.

You can try to fetch & merge with the latest update I pushed to ndnSIM-sample-topologies repo and check if it solves to the problem (https://github.com/cawka/ndnSIM-sample-topologies/commit/93b67c03051072264af90a0357b5b9fe8be6e47b).
