Hi! I am trying to run NDN modules, and I just add one line codes, "SendPkt(packet);", in line 133 of named-data.cc, to send the packet form application layer. But some error occurs when run "_named_dataexample" and the gdb message are as follows:

-----------Initializing simulation-----------

How can I fix this fault? Thank you for your attention and I look forward to your help。
