<blockquote type="cite">I remember I had the same question during the summer. It is indeed a hard problem. Using customized config file seems the best (only?) solution. But you have to be careful because the ndn-cxx library reads default configuration from
/usr/local/etc/ndn/client.conf, which is also shared across the system. In your applications you have to avoid using the default unix socket and explicitly specify the correct location.

<div style="margin-top:0px;margin-bottom:0px"><br>

<div style="margin-top:0px;margin-bottom:0px">1) Compiled ndn-cxx with a different sock file (/var/run/host1-nfd.conf) and then compiled NFD and moved the binaries to a folder on desktop. <br>

and changed the sock file name to <span style="font-family:Calibri,Arial,Helvetica,sans-serif;font-size:16px;background-color:rgb(255,255,255)">/var/run/host1-nfd.conf</span>. <br>

<div style="margin-top:0px;margin-bottom:0px"><br>
</div>
<div style="margin-top:0px;margin-bottom:0px">3) Started nfd from that folder using the following:<br>

<div style="margin-top:0px;margin-bottom:0px">./nfd --config <span style="font-family:Calibri,Arial,Helvetica,sans-serif;font-size:16px;background-color:rgb(255,255,255)">/usr/local/etc/ndn/</span><span style="font-family:Calibri,Arial,Helvetica,sans-serif;font-size:16px;background-color:rgb(255,255,255)">host1-nfd.conf</span><span> </span>&<br>

and ./nfdc works properly.</span><br>
