Re: New install of GNU Radio executes old version

Chris,

Here is what I have after cmake:

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.

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.

Take care,

Chris
