<p>NFD is built without websocket but nfd.conf for some reason has websocket section (maybe previous build of NFD that was compiled with websocket).</p>
<p>You could either use current sample conf:</p>
<p> sudo cp /usr/local/etc/ndn/nfd.conf.sample /use/local/etc/ndn/nfd.conf</p>

<div>Hello,<br>
<br>
I have run into new problem for the same process that I have done earlier.<br>
I have previously added a new fields to packet. (I had some issues while building tools and worked on that) And everything worked fine. In case someone wants to read that discussion, here is the link.<br>

I have added few more fields to packets. After making necessary changes I am building different packages. Following are the steps I followed.<br>

I am not really sure what I am doing wrong since I followed the exact same steps as I did last time. After rebuilding ndn-cxx, why is NFD startup is failing?</div>
<div><br>
I appreciate your time and guidance.<br>
Thanks,</div>
