<div dir="ltr">Hello Ashlesh. Thank you for the information.<br>
<br>
I didn't do that early. After doing the clean build, I could start the topology now. But I am getting the error when I run ndnping application. Same error.<br>
I will write the steps below that I did.<br>
<br>
Short Question - I am able to start the topology now. But I am getting same error now after running ndnping and ndnpingserver<br>

<div>I am not working on apps/ndn-consumer.cpp. I have modified the code in Forwarder.cpp to print the hopCountTag. I will test this using ndnping application.</div>

<div dir="ltr">Hello. I would really appreciate if someone can comment about these errors and the use case I am working on.<br>
<br>
Here is an update. I went through few more threads and I now understand the field type. I am using it as 901.<br>
ref - <a href="https://lo.calho.st/networks/adding-custom-packet-fields-to-packets-in-ndnsim-2-3-without-forking-the-entire-repository/" target="_blank">https://lo.calho.st/networks/adding-custom-packet-fields-to-packets-in-ndnsim-2-3-without-forking-the-entire-repository/</a><br>
<br>
However I am still getting the same error when I run minindn.<br>
<br>
<div dir="ltr">ERROR: unrecognized field 901 cannot be ignored1539063705.210205 FATAL: [nlsr.NlsrRunner] ERROR: unrecognized field 901 cannot be ignored<br>
<br>
Furthermore, I want to understand if this use case is possible.<br>
- First forwarder adds the timestamp to the interest packet and the I print this timestamp when the packet reaches the producer.<br>
- Can I achieve this using NDNLP, creating custom field ?<br>
<br>
Thanks<br>

After making the changes, I compiled, build and installed ndn-cxx package and then NFD package. It worked well. There are no errors.</div>
<div>Then I restarted nfd.<br>
(Meanwhile I had to to "sudo ldconfig" to fix issues)<br>
<br>
Question - I am getting following error when I start the default minindn topology. This is the field that is added as instructed.</div>
