[Discuss-gnuradio] Error in executing filtering example

[Ghulam Rasool Begh]

Hi all,

I was simulating filtering.grc example from Digital Modulation Primer using GNU Radio by Tom Rondeau. However during execution it gives following error. Can anybody help it out.

Executing: "/home/ehsan/mygn/filtering.py"

Traceback (most recent call last):

  File "/home/ehsan/mygn/filtering.py", line 119, in <module>

    tb = filtering()

  File "/home/ehsan/mygn/filtering.py", line 83, in __init__

    self.fft_filter_xxx_0 = filter.fft_filter_ccc(1, (), 1)

  File "/usr/local/lib/python2.7/site-packages/gnuradio/filter/filter_swig.py", line 677, in make

    return _filter_swig.fft_filter_ccc_make(*args, **kwargs)

RuntimeError: fft_impl_fftw: invalid fft_size

>>> Done

With Regards
