Since I already had installed ndnSIM using the instructions in Getting Started on the main ndnSIM.net page, I don't have to perform another git clone on ns-3-dev-ndnSIM.git or any of those files right? It seems it's just downloading a separate copy of ndnSIM to put in a separate directory. <b>So, all I did per the instructions was a git clone on the ndnSIM-scenario-template-git.<br></b></div></div></div></div></div></div></blockquote></span><div>You don't need to clone ns-3 or ndnSIM again, as long as you have compatible version.</div><span class=""><div><br></div><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><div dir="ltr"><div><div><div><div>2.) I placed the downloaded branch (terminology might be off here) in my-simulations, <b>which in turn I have inside the ndnSIM folder</b>.

I am very confused about the difference between the extensions and scenarios directories. I was under the impression I could put a subdirectory under extensions named as my scenario, so I named a subdirectory of extensions "jpb-strategy1-test", which contains jpb-strategy1.cpp and a umd/ directory with some classes I'm using (they worked fine with ndnSIM 2.1.) <b>Is this correct?<br></b></div></div></div></div></blockquote></span><div>You may place multiple files in extensions/ folder, which will be linked with every scenario.</div><div>Every file in scenarios/ folder is an individual simulation which must have a main() function.

Now, it cannot find the scenario, regardless of whether its inside extensions or scenarios. Does a .cpp or .cc file have to be at the top level or can I put a subdirectory? I just want to remain organized.
