Hi all


    I installed GNURadio according to the GnuRadio [Analog Devices Wiki] on my ubuntu 14.04 LTS to hope to access my fmcomms2 hardware. To my Zedboard, the version of firmware of SD card is 2014_R2, where the daemon program "iiod" can auto-run at Linux starting.  To the PC end, I load the file "iio-examples/fmradio" in GNURadio, and change the parameter of "Hostname" of "FMComms2 Source" to my Zedboard's IP address to run this flow graph. However, program failed. The Error message is :


Generating: "/opt/sd32gbak/gnuradio/iio-examples/"

Executing: "/opt/sd32gbak/gnuradio/iio-examples/"

Traceback (most recent call last):

  File "/opt/sd32gbak/gnuradio/iio-examples/", line 14, in <module>

    from gnuradio import iio

  File "/usr/local/lib/python2.7/dist-packages/gnuradio/iio/", line 33, in <module>

    from iio_swig import *

    _iio_swig = swig_import_helper()

  File "/usr/local/lib/python2.7/dist-packages/gnuradio/iio/", line 24, in swig_import_helper

    _mod = imp.load_module('_iio_swig', fp, pathname, description)

ImportError: /usr/local/lib/ undefined symbol: avahi_service_resolver_free


     Network is ok.

     Has any one can help me to fix this question or tell me what i missed ?
