You can checkout an example in examples/wscript for "ndn-simple-with-custom-app".</div><div><br></div><div>At the same time, I would encourage you and everybody else against writing scenarios by modifying ndnSIM or NS-3. My personal recommendation is to use a modular way, using for example the template <a href="https://github.com/cawka/ndnSIM-scenario-template">https://github.com/cawka/ndnSIM-scenario-template</a>. If you simply copy hijacker.cc to extensions folder and copy your modified version of ndn-tree-app-delay-trace (alongside with topology files), it should compile and work.</div><div><br></div><div>Let us know if you still in trouble with hijacker (either with or without modular way).</div><div><br></div><div>---</div><div>Alex</div><div><br></div><br><div><div>On Feb 25, 2013, at 11:14 PM, Chengyu Fan <<a href="mailto:chengyu@cs.colostate.edu">chengyu@cs.colostate.edu</a>> wrote:</div><br class="Apple-interchange-newline"><blockquote type="cite"><blockquote type="cite" style="color:rgb(34,34,34);font-family:arial,sans-serif;font-size:13px;background-color:rgb(255,255,255)"><div>Hi~</div><div><br></div><div>I want to use the custom app "hijacker" in ndnSIM, so I modify the code of ndn-tree-app-delay-tracer.cc.</div>
