[ndnSIM] [EXT] Error running a scenario after making a change

Right.

LocalControlHeader was deleted from ndn-cxx a few years back if I remember correctly.

Hi Pawan

Either "added a single line to the .cc file in the scratch folder" or "Our complete setup was working without any issues before adding this line" is false.
Did you perform any of the following actions?

  *   Upgrade or downgrade ndnSIM (e.g. git pull)
  *   Upgrade or downgrade the scenario template
  *   Upgrade or downgrade the ndn-cxx or NFD submodules

Most likely, one of the above is not ndnSIM v2.0, but a later version.
"LocalControlHeader" is present in ndnSIM v2.0 (released 5 years ago), but deleted in later versions.

Yours, Junxiao

Dear ndnSim team,

My research group had a scenario using ndnSim2.0 and it was running all good. I made a simple change to the scenario (added a single line to the .cc file in the scratch folder) and now when I try to run the scenario, it throws errors. Our complete setup was working without any issues before adding this line. Here are the error messages and I am not sure why a previously working system is throwing these errors.

I tried recompiling the project with ./waf configure and still, the error exists.

Thank you!
