Hi,</div>

<div>After my previous email, I continued installing NFD, Chronosync and PSync. Then, I had the same problem while installing NLSR: NLSR's linker could not find libPSync.so. So I tried the two suggestions provided by Alex (configuring /etc/ld.so.conf.d/local
and using ldconfig, and modifying the LD_LIBRARY_PATH variable). However, neither of these methods solved the problem.</div>
<div><br>
</div>
<div>So down I went to the rabbit hole, and I found that the origin of the problem is that when "./waf configure" looks for PSync, it runs the pkg-config program, which for Fedora 33, does not return the correct path for libPSync.so. The following is the section
where config.log records the results of its search for PSync:</div>
<div><br>
</div>
<div>----------------------------------------</div>
<div>Checking for 'PSync'</div>
<div>['/usr/bin/pkg-config', '--cflags', '--libs', 'PSync']</div>
<div>out: -lPSync </div>
<div><br>
</div>
<div>yes</div>
<div>----------------------------------------</div>
<div><br>
</div>
<div>And the following is the same record, but for Fedora 30:</div>
<div><br>
</div>
<div>----------------------------------------</div>
<div>Checking for 'PSync'</div>
<div>['/usr/bin/pkg-config', '--cflags', '--libs', 'PSync']</div>
<div>out: -I/usr/local/include -L/usr/local/lib64 -lPSync </div>
<div><br>
</div>
<div>yes</div>
<div>----------------------------------------</div>
<div><br>
</div>
<div>Since this is a Fedora issue, I opened a ticket to see if they could fix this problem. The ticket may be found here: https://bugzilla.redhat.com/show_bug.cgi?id=1953348</div>
<div><br>
</div>
<div>Unfortunately, they said that this may be considered "normal" behavior, since the correct output may be obtained through a similar command, pkgconf. They also said that they will not change pkg-config, unless more people complain.</div>
<div><br>
</div>
<div>I guess this is as far as I can go. I just wanted to let the NDN community know the end of this story.</div>
<div><br>
</div>
<div>Regards,</div>

Hi,<br>
<br>
<br>
I have found the following problem while installing NFD in Fedora 33: Following the same procedure described at the "A beginners guide to installing and testing NLSR on Fedora<<a href="https://named-data.net/doc/NLSR/current/beginners-guide.html">https://named-data.net/doc/NLSR/current/beginners-guide.html</a>>",
when I try to compile NFD using the ./waf command, there is an error saying "/usr/bin/ld.gold: error: cannot find -lndn-cxx". Initially I thought that I have not installed ndn-cxx correctly, so I checked my configuration and everything seemed to be as it should.
So I tried copying the ndn-cxx files from "/usr/local/lib64" to "/usr/lib" (libndn-cxx.so.0.7.1, libndn-cxx.so and pkgconfig). Then I ran the waf commands again and everything worked fine.<br>
<br>
I have installed NFD many times before in Fedora and I have not found this problem before. Is this an issue that needs to be reported as a bug? Or maybe there is another configuration step that needs to be added for Fedora 33. My previous NFD installation was
in Fedora 31.<br>
<br>
Regards,<br>
<br>

Fedora by default doesn't look for shared libraries under /usr/local. Not sure why, but this was the config for a long time (could be security related issue). Copying into /usr/lib works, but I would say it is not the best way.<br>
<br>
A better way is to update your dynamic linker config to include /usr/local/lib64 (and anything else you need). This can be as simple as adding a new file in /etc/ld.so.conf.d/local with just /usr/local/lib64 line in it; running `sudo ldconfig` afterwards.<br>
<br>
If you don't want to modify, you can also set some environment variable, but don't immediately remember which one.<br>
<br>
