Re: Relink error starting gnuradio

Answering my own question. Problem was caused by libraries under /usr/local/lib. I resolved it this way:

roger@homepc2:~$ sudo -i
root@homepc2:~# cd /usr/local/

root@homepc2:/usr/local# tar zcf lib.tar.gz lib/

root@homepc2:/usr/local# rm -fr lib/

root@homepc2:~# ldconfig
root@homepc2:~# logout

roger@homepc2:~$ gnuradio-companion
<<< Welcome to GNU Radio Companion 3.8.0.0 >>>

etc.

I installed it like this:

sudo add-apt-repository ppa:gnuradio/gnuradio-releases

sudo apt-get update
sudo apt install gnuradio

My environment:

$ whereis gnuradio-companion
gnuradio-companion: /usr/bin/gnuradio-companion /usr/share/man/man1/gnuradio-companion.1.gz

18.04.4 LTS (Bionic Beaver)

USRP B210 radio transceiver

History:

I originally installed gnuradio from package repo. Then I built it from source. Then I also built it with pybombs. It worked fine until I uninstalled everything and tried to install it with the package ppa.

I suspect it's not technically a gnuradio problem, but it's manifesting there through python3. Any idea how to clean this up? I'm not experienced with python.
