[ndnSIM] Not being able to build pretty much the same TypeId

[Muhammad Hosain Abdollahi Sabet]

Alex,

Sure! Here you are:
https://github.com/Mr-Norrell/PlayWithLink

This is for the application which is working:
https://github.com/Mr-Norrell/PlayWithLink/blob/master/extensions/Producer.cpp

And this is for the other one, which is not working:
https://github.com/Mr-Norrell/PlayWithLink/blob/master/extensions/Consumer.cpp

Thanks,
Sabet
