[Discuss-gnuradio] uhd_fft seg fault

[Daniel R. Marlow]

Hello,

  H/W:  Intel(R) Core(TM) i5-4430 CPU @ 3.00GHz
   USRP:  Ettus B210 
    OS:  Ubuntu 15.04
gnuradio:  3.7.5

   The most recent step was to do a simple binary install of uhd-host and 
gnradio using

  > sudo apt-get install uhd-host
  > sudo apt-get install gnuradio

   All seemed to work OK.     
   > uhd_usrp_probe 
   works as expected (displays info about B210)

   However, when I try to run 
    > uhd_fft -f 1420M
    the program seg fautls.
   
    The same is true when I try 
    > gnuradio-companion
    and also
    > python top_block_ex.py
     where top_block_ex.py is a known-to-work module from another project.

   See the screen dump below.   I don't believe it's a windows issue, since 
other apps open windows without problems.     Full disclosure:  installation of 
the binaries was preceded with a PyBOMBS installation (which seemed to go OK, 
except that uhd_usrp_probe was not found)

   Any suggestions would be most appreciated.   (Sorry if this is hopelessly 
naive.)
