Hi Aniket,

If you see that "ndnSIM" is enabled and 'configure' finished successfully, there is no reason to panic :)  Everything got configured correctly and the script just reporting what has been found and what has not.

The error is not related to ndn-simple.cpp, but to RemoteSystemTempFiles "scenario" that you have in your NS-3's scratch folder.  The scratch folder assumptions about how it handles .cpp files directly placed in the scratch folder (those assumed to be complete scenarios and must include main() function) and files places in a subdirectory in the scratch folder (those will be compiled into a single scenario and one of the files must have main() function).  From the error, I see that you haven't defined main() function in any of the scenario files in /home/a/KL/ndnsim/ns-3/build/scratch/RemoteSystemsTempFiles/RemoteSystemsTempFiles/ folder
