[Mini-NDN] Add a Hop count to interest/data packet - unrecognized field 84 cannot be ignored

Mon Oct 8 14:40:12 PDT 2018

Hello All,

I am following the steps mentioned here,
https://www.lists.cs.ucla.edu/pipermail/ndnsim/2016-December/003254.html

After making the changes, I compiled, build and installed ndn-cxx package
and then NFD package. It worked well. There are no errors.
Then I restarted nfd.
(Meanwhile I had to to "sudo ldconfig" to fix issues)

Question - I am getting following error when I start the default minindn
topology. This is the field that is added as instructed.

[FULL LOG Pasted below - See the error at the end]
