Hi Alex,</p>
<p style="color: rgb(0, 0, 0); font-family: Calibri, Arial, Helvetica, sans-serif; font-size: 12pt;">
<br>
</p>
<p style="color: rgb(0, 0, 0); font-family: Calibri, Arial, Helvetica, sans-serif; font-size: 12pt;">
I tried writing the code in ndnSIM/apps folder and it worked fine.</p>
<p style="color: rgb(0, 0, 0); font-family: Calibri, Arial, Helvetica, sans-serif; font-size: 12pt;">
<br>
</p>
<p style="color: rgb(0, 0, 0); font-family: Calibri, Arial, Helvetica, sans-serif; font-size: 12pt;">
But when I use the same code in scenario folder (used scenario template of yours) it fails as i mentioned. </p>
<p style="color: rgb(0, 0, 0); font-family: Calibri, Arial, Helvetica, sans-serif; font-size: 12pt;">
<br>
</p>
<p style="color: rgb(0, 0, 0); font-family: Calibri, Arial, Helvetica, sans-serif; font-size: 12pt;">
It must be something regarded to the scenario template.....</p>
<p style="color: rgb(0, 0, 0); font-family: Calibri, Arial, Helvetica, sans-serif; font-size: 12pt;">
As if I include the file "ns3/ndn-forwarding-strategy.h" it says my variable(set container) is not defined, </p>
<p style="color: rgb(0, 0, 0); font-family: Calibri, Arial, Helvetica, sans-serif; font-size: 12pt;">
<font color="#808080">../extensions/testsimple.cc:109:19: error: ‘class ns3::ndn::ForwardingStrategy’ has no member named ‘m_allowCS’</font></p>
<p style="color: rgb(0, 0, 0); font-family: Calibri, Arial, Helvetica, sans-serif; font-size: 12pt;">
so I have to include the complete path to the above header file. Then it compiles fine. but end abruptly. </p>
<p style="color: rgb(0, 0, 0); font-family: Calibri, Arial, Helvetica, sans-serif; font-size: 12pt;">
<br>
</p>
<p style="color: rgb(0, 0, 0); font-family: Calibri, Arial, Helvetica, sans-serif; font-size: 12pt;">
<br>
</p>
<p style="color: rgb(0, 0, 0); font-family: Calibri, Arial, Helvetica, sans-serif; font-size: 12pt;">
In the terminal I just want to confirm whether the program works by looking at the log messages.</p>
<p style="color: rgb(0, 0, 0); font-family: Calibri, Arial, Helvetica, sans-serif; font-size: 12pt;">
<br>
</p>
<p style="color: rgb(0, 0, 0); font-family: Calibri, Arial, Helvetica, sans-serif; font-size: 12pt;">
I attached the following files which I modified.</p>
<p>../scenario/extensions/testsimple.h - modified from ndn-producer</p>
<p>../scenario/extensions/testsimple.cc</p>
<p>../scenario/scenarios/simple.cc - modified from ndn-simple</p>

Many Thanks,</p>

<div>Hi Isuru,</div>
<div><br>
</div>
<div>I have tried to follow your implementation (added set container in the forwarding strategy and the added a prefix in StartApplication). Everything worked as expected.</div>
<div><br>
</div>
<div>If you can share your code, I can try to run it and see what is wrong.</div>
<div><br>
</div>
<div>Btw. What are you expecting to see on the terminal?</div>
<div><br>

<div>
<div>Hi Isuru,</div>
<div><br>
</div>
<div>Are you running simulation in the visualizer? Try to run without it and in debug mode (in case you have compiled with ./waf configure -d optimized, re-compile with ./waf configure -d debug or just ./waf configure).</div>
<div><br>
</div>
<div>The variable declaration seems right. The problem that I could think of is that you're trying to use it in application's constructor, when neither Node() nor strategy objects are not yet set.</div>
<div><br>
</div>
<div>Btw. What the effect you're trying to achieve? Normally (in "real world") applications cannot directly communicate with the forwarding daemon. Or is it something that is simulation-specific?</div>
<div><br>

<div>
<div>Is it just terminates without any output or terminates with an error?</div>
<div><br>
</div>
<div>If it is an error, then try to run in a debugger, so you can see what exactly is causing the error. For example,</div>
<div><br>
</div>
<div>./waf --run <scenario> --command-template 'gdb --args %s'</div>
