[Discuss-gnuradio] ofdm mod error

[Patrcia Wonder]

Hi! I'm using gnuradio on ZedBoard and was trying a simple OFDM Mod
system just like in this video
https://www.youtube.com/watch?v=LZDWfnrxo6c

the flowgraph just looks like this... random source>short to float>ofdm
mod>throttle>wx gui fft sink

and this comes up...

"Generating: "/home/analog/Documents/top_block.py"

Executing: "/home/analog/Documents/top_block.py"

Fontconfig warning: ignoring C.UTF-8: not a valid language tag
Using Volk machine: neon_hardfp
Traceback (most recent call last):
  File "/home/analog/Documents/top_block.py", line 101, in <module>
    tb = top_block()
  File "/home/analog/Documents/top_block.py", line 62, in __init__
    verbose=None,
  File "/usr/lib/python2.7/dist-packages/gnuradio/digital/ofdm.py", line
95, in __init__
    constel = psk.psk_constellation(arity)
  File "/usr/lib/python2.7/dist-packages/gnuradio/digital/psk.py", line
77, in psk_constellation
    constellation = digital_swig.constellation_psk(points,
pre_diff_code, m)
AttributeError: 'module' object has no attribute 'constellation_psk'

>>> Done"

I have no idea what to do next...

THANKS! :)
