[ndnSIM] When I try to use trace source, the comepile errors are Occured.

[박종인]

Hi all,

I want to trace ReceivedInterests and ReceivedDatas.
So I use ConnectWithoutContext functions to connect the traceSources to my callback functions.

Config::Connect("/NodeList/*/ApplicationList/*/$ns3::ndn::App/ReceivedInterests",MakeCallback(&WillBeCalledWhenInterestIsReceived));
Config::Connect("/NodeList/*/ApplicationList/*/$ns3::ndn::App/ReceivedDatas", MakeCallback(&WillBeCalledWhenDataIsReceived));

And, my Callback functions are like this,

void
WillBeCalledWhenInterestIsReceived( std::shared_ptr<const ndn::Interest> i, Ptr<ndn::App> a, std::shared_ptr<ndn::Face> f )
{
       cout << "Interest is Received at " << f->getId() << "\t" << i->getName().toUri();
}

void
WillBeCalledWhenDataIsReceived( shared_ptr<const ndn::Data> d , Ptr<ndn::App> a, shared_ptr<ndn::Face> f )
{  
     cout << "Data is Received at " << f->getId() << "\t" << d->getName().toUri() << "\t" << d->getContent().value();
}

When I try to compile this source code, I got Errors like this,

Am I do anything wrong?
I need your help !! ☹


Thanks in advance,
