The error I get is: Code: one.cpp:8:29: fatal error: ns3/core-module.h: No such file or directory compilation terminated. This how I am compiling: Code: g++ -o one one.cpp Can someone please explain how to compile this code through the command line? Note: When I try to compile using Geany it compiles fine. (Hardware)
