[Discuss-gnuradio] GSoC: Filter Design tool update
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,
Mac / AE5PH
