[ndnSIM] What is the correct namespace

Your second argument (testNode) is of type Ptr<Node>, but AddOrigins
requires a NodeContainer:

see the examples:

https://ndnsim.net/2.3/examples.html

AND documentation for NodeContainer:

https://www.nsnam.org/~pdbarnes/docs-related/classns3_1_1_node_container.html

Thanks,

John

Hi John,

Thank you for you reply, your suggestion really works! While after i
compile the code, i got the error:

no matching function for call to
‘ns3::ndn::GlobalRoutingHelper::AddOrigins(std::string&,
ns3::Ptr<ns3::Node>&)’
         ndnGlobalRoutingHelper.AddOrigins(prefix, testNode);

      ^

I don't know why the error will happen, cause the code

ns3::Ptr<ns3::Node> testNode = ns3::Names::Find<ns3::Node>(tNode);

now works well, the form of "testNode" is apparently ns3::Ptr<ns3::Node>?

Thank you!

Perhaps you are missing #include directives?  For example, names.h is where
Names lives.

Names is a class declared in ns3, and inside ns3 namespace.

So ns3::Names::Find might work?

And GlobalRoutingHelper is in ndn-global-routing-helper.h

Does this help?
