Hi everyone!<br>when I configured and compiled NS-3 in optimized mode (<tt class="docutils literal"><span class="pre">./waf</span> <span class="pre">configure</span> <span class="pre">-d</span> <span class="pre">optimized</span></tt>) in order to run actual simulations, it couldn't include visualizer model. Then I still  haven't completed environment to run the visualizer after using the following commands:<br><code>cd ndnSIM/ns-3
<br>./waf shell<br></code>where is my error? please tell me? <br>                                                                     shili<br>
