Can you provide more information on what exactly failed or this is all the output you're seeing? sudo should be used only for installation stage (e.g., for sudo ./waf install), all other stages should be run without.

We have seen something remotely related to this and it was because of different versions of python picked up by the system without and with python (e.g., you may be using pyenv which is not used after sudo). You can try to run /usr/bin/python waf and sudo /usr/bin/python waf to check whether it fixes the issue.

Hi Alex,

Thanks for replying.

Now there are two cases, of which the first is:

If run waf configure without sudo, then it can't detect libndn-cxx, but I already include the path to libndn-cxx.pc in PKG_CONFIG_PATH, as following shows:

$ echo $PKG_CONFIG_PATH
/usr/lib/x86_64-linux-gnu/pkgconfig:/usr/lib/pkgconfig:/usr/share/pkgconfig:/usr/local/lib/pkgconfig:/usr/lib/x86_64-linux-gnu/pkgconfig:

$ sudo ls /usr/local/lib/pkgconfig/
libcdt.pc  libcgraph.pc  libgvc.pc  libgvpr.pc  liblab_gamut.pc  libndn-cxx.pc  libpathplan.pc  libxdot.pc

so  second case is run waf configure with sudo ( or with sudo  /usr/bin/python):
then configure can be successfully done, but failure comes still in running waf ( with sudo /usr/bin/python):

Appreciate your help!

Someone in our lab was having the same problem. Older version of ndn-cxx is being detected which does not have ndn::nfd::FaceMonitor::FaceMonitor(ndn::Face&). In our case it was because NFD was installed from PPA earlier. So removed the PPA, deleted the ndn-cxx library installed by the PPA and installed the latest ndn-cxx from source.
(You can check the output of ldconfig -p | grep ndn to see where the ndn-cxx lib is installed from PPA and whether it has multiple versions installed).

Hi, thanks for the solution.
I did install from PPA previously, and after removing them, still met with similar failure.

But just tried to clone the original repos and then it built successfully......(previously I cloned the folk repo)

No idea why, but anyway, now it built.

In the future, this kind of support requests should be posted to nfd-dev mailing list. Also, see http://www.lists.cs.ucla.edu/pipermail/nfd-dev/2016-May/001748.html on how to effectively help developers reproduce your problem.

Hi, thanks, I'll follow the instructions in the future.
