Hi,
<div><br>
</div>
<div>Just met another problem when using “./waf xxxx —vis” command. It indeed gave me output showing the network topology. But I still get the errors below. I’m sure kiwi is installed successfully.</div>

<div>Hi Yitong, </div>
<div dir="auto"><br>
</div>
<div dir="auto">Let me explain briefly about what is happening during the installation. ndnSIM is an external module for ns-3. When you run the installation script, it pulls a patched version of ns-3, and then place the actual ndnSIM module inside ns-3 as /src/ndnSIM. </div>
<div dir="auto"><br>
</div>
<div dir="auto">When you want to run something, you would want to run it in ns-3 (not in the src folder). Normally, you wouldn't need to modify the wscript file if you place your codes in the /scratch folder. According to the root wscript (<a href="https://github.com/named-data-ndnSIM/ns-3-dev/blob/1b3bab9b6dba5f1e616c0b286eb889e9ce3d5d59/wscript#L1034" rel="noreferrer" target="_blank">https://github.com/named-data-ndnSIM/ns-3-dev/blob/1b3bab9b6dba5f1e616c0b286eb889e9ce3d5d59/wscript#L1034</a>),
it will add files with extension ".cc".</div>
<div dir="auto"><br>
</div>
<div dir="auto">If your code does not end with .cc, you should rename it. If your code base is not a single file, you need create a folder inside /scratch to add your program as a folder. If nothing works, let me know or try tinkering with wscript. It's written
in Python. </div>
<div dir="auto"><br>
</div>
<div dir="auto">Good luck! </div>

<div>Hi Yitong,</div>
<div><br>

<div>You need to add an entry to the "wscript" file in the same directory you run ./waf. You can modify the script to make it either run on "/scratch" or "/examples".</div>

<div>I’m confused about which directory should I store my .cpp in order to run it. I’ve tried putting them into "/scratch” and “/src/ndnSIM/examples”, my program is named “non-first.cpp”. Then I use "./waf --run ndn-first” to run it. An error shows that “program
