Thanks for getting back to me. The packages I installed were: - libqwtplot3d-qt4-0v5, libqwtplot3d-qt4-dev from apt install - qwt-6.1.0 (not the most recent, but what the page recommends), from source. I'd previously tried installing the most recent from the repos (apt), but had the same error I mentioned above so uninstalled and installed this recommended version from source. - I installed this using these instructions: http://qwt.sourceforge.net/qwtinstall.html
gr-inspector (cmake) had errors until I did these three things: - apt install gnuradio-dev - ln -s /usr/include/qwt /usr/include/qwtplot3d-qt4 - ln -s /usr/lib/libqwt-qt4.so.5 /usr/lib/libqwt-qt4.so - I found that I had to do this: export CMAKE_MODULE_PATH=/home/rs/devel/gr-inspector/cmake/Modules; cmake .. So, either I am doing something wrong by this point, or there are four extra steps (above) that are required to get gr-inspector working on my system (Ubuntu 17.10, gnuradio 3.7.10) I've cleaned and built again to show the output. Here is the output of 'cmake ..': https://pastebin.com/c3hnmNDx Here is the output of 'make -j4': https://pastebin.com/zHUAZGn3 I load the sample graph into gnuradio-companion, and get the error again: https://pastebin.com/DFGAtmGz As for the PLL error (while tuning the rtl-sdr), that's something I normally experience. It's never been a show-stopper and I think it can be ignored in this case. I am not tuning to 2.4MHz but am using a 2.4MS/s sample rate.
