build errors!

[ra7ul]

when I do what README says, it showed like below after the step'./waf': .
./src/ndnSIM/helper/ndn-global-routing-helper.cc:242:68: error: typedef ‘vertex_descriptor’ locally defined but not used [-Werror=unused-local-typedefs]
typedef graph_traits < NdnGlobalRouterGraph >::vertex_descriptor vertex_descriptor;
^
../src/ndnSIM/helper/ndn-global-routing-helper.cc: In static member function ‘static void ns3::ndn::GlobalRoutingHelper::CalculateAllPossibleRoutes()’:
../src/ndnSIM/helper/ndn-global-routing-helper.cc:332:68: error: typedef ‘vertex_descriptor’ locally defined but not used [-Werror=unused-local-typedefs]
typedef graph_traits < NdnGlobalRouterGraph >::vertex_descriptor vertex_descriptor;
^
cc1plus: all warnings being treated as errors
how should I do?

Given your compiler is overly cautious, you need to remove "-Werror" flag, which is always included during NS-3 compilation. You can take solution from cawka/ns-3-dev-ndnSIM@965856d commit

Thank you for your nice reply! I have got 'build' finished successfully. But, Im getting a new error after this, and I'm having a hard time figuring it out, it says 'OSError: [Errno 2] No such file or directory'.The whole messages as follows:
