ChronoSync

I have a problem when I build the ChronoSync on my mac, after I do the ./waf action, the error comes when linking the "build/libChronoSync.dylib".
the warning massages are as follow:

  NOTE: a missing vtable usually means the first non-inline virtual member function has no definition.

I really checked the prerequisite on ndn-cxx website and there are nothing missed, so I was wondering the reason of that fail. I would be really appreciate if anyone of the team can help me. Thanks!
