Re: [Discuss-gnuradio] Error messages when running gr_filter_design for gnuradio 4.7 on MacPorts

[Michael Dickens]

Hi Albert - On my end as the maintainer of the gnuradio* ports in MacPorts, 
I'll add a runtime dependency on py*-pyqwt for gr-utils.  It'll be a little 
tricky since I have to get the variants to match up (the variant for pyqwt and 
which version of qwt is installed), but it can be done.

Tom - Do you know if the 2 gr-utils which depend on pyqwt (gr_filter_design and 
gr_plot_qt) will work with qwt5 and qwt6?  RIght now they try to import PyQwt5, 
but maybe the import test could be changed to try for PyQwt6 first then if that 
fails PyQwt5?  I've set up the gnuradio* ports to not care which version of qwt 
is installed (5 or 6; via depending on "path:lib/libqwt.dylib:qwt" which looks 
for the library first and if that is not found then port reverts the dependency 
to qwt which is version 5.1.2) -- so, requiring qwt version 5 in these scripts 
seems to counter my settings.  Hence, my question. - MLD
