I guess your ndn-cxx is not the latest one. Recently, some change has been made in the scheduler (<a href="https://github.com/named-data/ndn-cxx/commit/a5f233e103453f6157715b0cec0997658c4ec075" target="_blank">https://github.com/named-data/ndn-cxx/commit/a5f233e103453f6157715b0cec0997658c4ec075</a>).
I suggest you to compile the latest ndn-cxx and retry.

The easiest way that I know of to install ndn-cxx and NFD on the Pi is from source on raspbian OS using clang (not the default gcc as it requires extending swap and is up to 10 times slower). Example:<br>

<div>It was nice to talk to you. I’m cc’ing Ashlesh Gawande who can answer Ahmed’s questions about the installation.
