<p>Hi Alex,</p>
<p><br>
</p>
<p>I compiled without the -d optimized and ran without the visualizer. </p>
<p>Then it just compile and nothing is displayed in the terminal.</p>
<p><br>
</p>
<p>I entered the code in StartApplication() function.</p>
<p><br>
</p>
<p>I was trying to build a collaborative caching application.</p>
<p><br>
</p>
<p><font color="#808080">Ptr<ForwardingStrategy> forwardingstat = GetNode()->GetObject<ForwardingStrategy>();</font></p>
<p><font color="#808080">Ptr<Name> inName = Create<ndn::Name> ("/prefix/thisfix/");</font></p>
<p><font color="#ff0000">forwardingstat->addAllowCS(inName);</font></p>
<p><font color="#ff0000"><br>
</font></p>
<p>If I comment out the third line(line in red) it works fine.</p>
<p><br>

<p>Many Thanks,</p>

<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>
<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>

Hi,
<div><br>
</div>
<div>In ndn-forwading-strategy.h, I declared variable.</div>
<div><font color="#808080">std::set<Name> m_allowCS;</font></div>
<div><br>
</div>
<div>and tried to access in one of the applications by following code</div>
<div>
<div><font color="#808080">Ptr<ForwardingStrategy> forwardingstat = GetNode()->GetObject<ForwardingStrategy>();</font></div>
<div><font color="#808080">Ptr<Name> inName = Create<ndn::Name> ("/prefix");</font></div>
<div><font color="#808080">forwardingstat->m_allowCS.insert(*inName);</font></div>
</div>
<div><br>
</div>
<div>This compiles fine.</div>
<div>but once I run this, simulator exit without any output. Could you point out what's wrong.</div>
<div><br>
</div>
<div>Many Thanks,</div>
