[SUBODH MISHRA]

Dear all
I just want to calculate the total number of received data packet on the
consumer in the ndn-simple.cpp. I used the following code in which i used
the callback function named Client as well as global variable r to count
the number of packets.

#include "ns3/core-module.h"
#include "ns3/network-module.h"
#include "ns3/point-to-point-module.h"
#include "ns3/ndnSIM-module.h"

namespace ns3 {

int r;
void Client(Ptr<const ndn::Data> d, Ptr<const ndn::App> app, Ptr<const
ndn::Face> f)
{
std::cout<<"Total data packets recieved"<<r++<<endl;
}





int main(int argc, char* argv[]) {


     Config::SetDefault("ns3::PointToPointNetDevice::DataRate",
StringValue("1Mbps"));
     Config::SetDefault("ns3::PointToPointChannel::Delay",
StringValue("10ms"));
     Config::SetDefault("ns3::QueueBase::MaxSize", StringValue("20p"));

     // Read optional command-line parameters (e.g., enable visualizer with
./waf --run=<> --visualize
     CommandLine cmd;
     cmd.Parse(argc, argv);

     // Creating nodes
     NodeContainer nodes;
     nodes.Create(3);

     // Connecting nodes using two links
     PointToPointHelper p2p;
     p2p.Install(nodes.Get(0), nodes.Get(1));
     p2p.Install(nodes.Get(1), nodes.Get(2));

     // Install NDN stack on all nodes
     ndn::StackHelper ndnHelper;
     ndnHelper.SetDefaultRoutes(true);
     ndnHelper.InstallAll();

     // Choosing forwarding strategy
     ndn::StrategyChoiceHelper::InstallAll("/prefix",
"/localhost/nfd/strategy/multicast");

     // Installing applications

     // Consumer
     ndn::AppHelper consumerHelper("ns3::ndn::ConsumerCbr");
     // Consumer will request /prefix/0, /prefix/1, ...
     consumerHelper.SetPrefix("/prefix");
     consumerHelper.SetAttribute("Frequency", StringValue("10")); // 10
interests a second
     auto apps = consumerHelper.Install(nodes.Get(0));
   // first node
     apps.Stop(Seconds(10.0)); // stop the consumer app at 10 seconds mark

     // Producer
     ndn::AppHelper producerHelper("ns3::ndn::Producer");
     // Producer will reply to all requests starting with /prefix
     producerHelper.SetPrefix("/prefix");
     producerHelper.SetAttribute("PayloadSize", StringValue("1024"));
     producerHelper.Install(nodes.Get(2)); // last node
     Config::Connect("/NodeList/0/ApplicationList/*/ReceivedDatas",
MakeCallback(&Client));
     Simulator::Stop(Seconds(20.0));

     Simulator::Run();
     Simulator::Destroy();

     return 0;
   }

  // setting default parameters for PointToPoint links and channels

}

 // namespace ns3

int
main(int argc, char* argv[])
{


return ns3::main(argc, argv);


}
I am recieving the following error:-
