Hi Jim, Firstly, let me tell you that I haven't ever tried installing on a Pi, so I may be missing some nuances. Apologies if that's the case.
After step 5 gnuradio-companion should be in /usr/bin based on the steps you took. If gnuradio-companion is not in /usr/bin I suspect that something was missing from your build. Given your cmake command, you will not need to set LD_LIBRARY_PATH and PYTHONPATH. That's only necessary if you didn't set -DCMAKE_INSTALL_PREFIX=/usr . You should get something like the following at the end of your cmake command. -----SNIP----- -- ###################################################### -- # Gnuradio enabled components -- ###################################################### -- * testing-support -- * python-support -- * post-install -- * doxygen -- * man-pages -- * gnuradio-runtime -- * common-precompiled-headers -- * gr-ctrlport -- * * thrift -- * gnuradio-companion -- * JSON/YAML config blocks -- * gr-blocks -- * gr-fec -- * gr-fft -- * gr-filter -- * gr-analog -- * gr-digital -- * gr-dtv -- * gr-audio -- * * alsa -- * * oss -- * * jack -- * * portaudio -- * gr-channels -- * gr-pdu -- * gr-iio -- * * libad9361 -- * gr-qtgui -- * gr-trellis -- * gr-uhd -- * gr-uhd UHD 4.0 RFNoC -- * gr-utils -- * gr_modtool -- * gr_blocktool -- * gr-video-sdl -- * gr-vocoder -- * * codec2 -- * * freedv -- * * gsm -- * gr-wavelet -- * gr-zeromq -- * gr-network -- * gr-soapy -- -- ###################################################### -- # Gnuradio disabled components -- ###################################################### -- -- Using install prefix: /usr -----SNIP----- Ensure gnuradio-companion is on the list. Also note if you have any components in the disabled components list. Once make install has completed you should have, roughly speaking, the following directories / files. /etc/gnuradio - all the system configuration files /usr/bin/gnuradio-companion /usr/lib/libgnuradio* - all the c++ libraries /usr/lib/python3.9.2/site-packages/gnuradio - all the python components /usr/share/gnuradio/grc/blocks - all the blocks files /usr/include/gnuradio - c++ header files Cannot import gnuradio means python can't find the gnuradio directory and it's contents in the "python components". This is critical as gnuradio-companion is all python driven. If you have all these directories, perhaps a review of https://wiki.gnuradio.org/index.php?title=LinuxInstall#Installing_Volk to see if you missed a step. (maybe running sudo ldconfig or something like that.) Anyway hoping you get this working. Let me know if you're missing anything.
