Hi Robert,

I have cloned and installed gr-inspector using the instructions on the webpage. One change (addition) necessary to get gr-inspector to install on my system (Ubuntu 17.10) was to run ln -s /usr/lib/libqwt-qt4.so.5 /usr/lib/libqwt-qt4.so ; otherwise cmake failed, unable to find libqwt-qt4.so.
Can you please provide a *complete* list of qwt packages you installed as well as the version? (For instance with `dpkg -s [package]`) Also, please provide the output of cmake when before and after the `ln -s` command you mention. Lastly, I’d like to see the output of `make` after a successful cmake run. You can use pastebin or something similar since this all is a lot of output. I have started gnuradio companion and loaded an example from gr-inspector (live_signal_detection.grc). I adjust the sample rate, since I am using an RTL-SDR (adjust to 2.4e6). The graph comes up, and I press 'play' (execute the flow graph). I get this error:
Found Rafael Micro R820T tuner
[R82XX] PLL not locked!
[R82XX] PLL not locked!
I’m not aware of any RTL SDRs that can be tuned to 2.4 MHz (correct me if I’m wrong). That’s probably why you get the PLL error here.

This just means gr-inspector was not installed correctly. To investigate, please provide the outputs I mentioned above. Cheers,
