Re: [Discuss-gnuradio] GSoC: Filter Design tool update

[Mac A. Cody]

Hello,

I downloaded your updates to the filter design tool from
https://github.com/zeroXzero/gr-filtdes (zeroXzero-gr-filtdes-6cd8f37.zip)

After unzipping the archive, I followed the build instructions, using
the cmake command, as follows:

cmake -DCMAKE_INSTALL_PREFIX:PATH= /home/mcody/.../zeroXzero-gr-filtdes-6cd8f37 /usr/local

The build and install appeared to proceed well, but when I execute
gr_filter_design at the command prompt, I get the following error message:

Traceback (most recent call last):
  File "/usr/local/bin/gr_filter_design", line 55, in <module>
    from filtdes.banditems import *
  File "/usr/local/lib/python2.6/dist-packages/filtdes/banditems.py", line 193, in <module>
lpfItems.append(lpfsLines())
  File "/usr/local/lib/python2.6/dist-packages/filtdes/banditems.py", line 79, in __init__
    self.poly << QtCore.QPointF(3,5)
TypeError: unsupported operand type(s) for <<: 'QPolygonF' and 'QPointF'

Prior to running gr_filter_design, I had to set LD_LIBRARY_PATH
to /usr/local/lib.

I don't know what I am doing wrong. Should your distribution be placed in
a specific location?  I am using GNU Radio 3.6.1git-47-g884c23ef if that
is of any help. I am running Kubuntu 10.04.

Thanks,
