Problem – sdrplay with GNU radio 3.10.1 installed via Ubuntu 22.04

[RabbitEarsParticipant]

I can get my RSP2 working with just the API, soapysdr and soapysdrplay3 writing simple python code but cannot get the soapy blocks or the gr-sdrplay block running. I haven’t tried the osmocon block as the problem appears to be common across blocks.

At this point not sure where I should be seeking help (ubuntu soapy soapysdrplay or gnuradio or gr-sdrplay3) Hoping someone here can advise what decency is version mismatched.

Generate and run messages using sdrplay3 block which I believe is the block installed from gr-sdrplay3-3.10.0.2 install

Configuration
##############################################################################
Ubuntu 22.04
Python Version 3.10.6

The following were loaded using scripts from SDRPlay website.
SDRPLAY API Version 3.07
SoapySDR Version 0.8.1
SoapySDRPlay3 Version 0.4.1

This was loaded as an apt-get
GNU Radio Version 3.10.1.1 (Python 3.10.6)

This was loaded as a tartball download from git as clonable version only gnuradion V3.9 compatable. Ubuntu 22.04 installs V 3.10.1.1
gr-sdrplay3 Version 3.10.0.2
############################################################################

What works, what doesn’t
$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$
I can control and stream RSP2 using API soapysdr & SoapySDRPlay3. Without GNU Radio
Neither the gr-sdrplay3 nor the soapy deprecated or RSP2 source blocks work

Hoping someone can assist with where the problem lies. I’m assuming its a mismatch of version dependencies. Either a filename has changed or its location. If someone cleverer than I can try this and advise where I should be posting the problem. (ubuntu, sdrplay or gnuradio.) I have looked at the sdrplay scripts and they are cloning latest git repositories.

From a clean install 19/2/2023

Ubuntu 22.04
1.installAPI.sh
2.buildsoapy.sh
sudo apt-get install gnuradio

I haven’t installed gr-sdrplay3 as this is already failing here.

using simple grc file with soapy sdrplay source block and qt-gui fft gives the following

ok I have solved the issue with gr-sdrplay3 OOT

It installs these files

/usr/local/lib/x86_64-linux-gnu/libgnuradio-sdrplay3.so.3.10.3.0
/usr/local/lib/x86_64-linux-gnu/libgnuradio-sdrplay3.so.3.10.3
/usr/local/lib/x86_64-linux-gnu/libgnuradio-sdrplay3.so

but they needed to be moved from the /usr/local path above and put under the /usr/lib path as below.

/usr/lib/x86_64-linux-gnu/libgnuradio-sdrplay3.so.3.10.3.0
/usr/lib/x86_64-linux-gnu/libgnuradio-sdrplay3.so.3.10.3
/usr/lib/x86_64-linux-gnu/libgnuradio-sdrplay3.so

Fixedf and closed. I’ll live without the soapy sdrplay sources as they are not as encompassing as the gr=sdrplay3 OOT module

Hope this helps anyone else trying to load gnuradio and sdrplay under Ubuntu 22.04.02

Hello,

I have the same configuration than you so I also install gr-sdrplay3 OOT, but now I have this error :

File “/usr/local/lib/python3.10/dist-packages/gnuradio/sdrplay3/__init__.py”, line 24, in <module>
from .sdrplay3_python import *
ImportError: libgnuradio-sdrplay3.so.3.11.0git: cannot open shared object file: No such file or directory

I move the libgnuradio-sdrplay3.so.3.11.0git file to /usr/local/lib/python3.10/dist-packages/gnuradio/sdrplay3/, but the problem remains the same.

Do you have some advice ?
