Re: [Discuss-gnuradio] qt frequency sink runtime error

[Kyeong Su Shin]

Dear Ruedi,

I am pretty sure that Ubuntu 14.04 does not come with GNU Radio 3.7.11.1, so you cannot simply apt-get it from the official repo. Did you add a PPA or use any other installation methods by any chance? If so, did you remove the previous version of GNU Radio (if you installed it before) before installing the newer version?

Regards,

Kyeong Su Shin

Huh, odd, that looks like it should, and that runs just well on my
3.7.12 (don't remember there being a related bug fix since 11); soooooo,
I'll need to read that couple lines of code in Python that your GRC
generates (and mine doesn't). Can you also share your
/tmp/resampler_demo.py ?

Thanks!
Marcus

Dear Ruedi,

That's pretty interesting; could you use GRC's screen capture
functionality to share what the flow graph looks like on your machine? I
sense GNU Radio bugs!

Best regards,
Marcus

Hello,

I'm using gnuradio-companion 3.7.11.1 installed using apt-get on
Ubuntu 14.04.5 LTS running on a Lenovo T60.

The dialtone example works fine but once I'm using the frequency sink
like e.g. in the resampler_demo.grc I get the following Runtime Error:

Generating: '/tmp/resampler_demo.py'

Executing: /usr/bin/python2 -u /tmp/resampler_demo.py

Traceback (most recent call last):
    File "/tmp/resampler_demo.py", line 284, in <module>
      main()
    File "/tmp/resampler_demo.py", line 272, in main
      tb = top_block_cls()
    File "/tmp/resampler_demo.py", line 104, in __init__
      1 #number of inputs
    File
"/usr/local/lib/python2.7/dist-packages/gnuradio/qtgui/qtgui_swig.py",
line 1371, in make
      return _qtgui_swig.freq_sink_c_make(*args, **kwargs)
RuntimeError: std::exception

Any ideas?

Best wishes,

Ruedi
