Is anyone else having this problem with 'undefined symbol ’ ? Do I need
to
rebuild (or re-install ) libgnuradio-core-3.4.0git.so.0 ?

Perhaps a mismatch between the headers you compiled against and the
libraries you linked against. Just a guess, but if thats the case you
should clean your system and reinstall gr.
