Building on headless pi5 / bookworm

[BobSelf22]

I've installed SDRplay_RSP_API-Linux-3.14.0. That works.
I installed gnuradio from the bookworm repository.
gnuradio-config-info --version
3.10.5.1
so far, so good.

I built and installed gr-sdrplay3. I didn't notice any fatal errors.

When I run a no-gui python script it fails on this line:
from gnuradio import sdrplay3:
Traceback (most recent call last):
File "/usr/local/lib/python3.11/dist-packages/gnuradio/sdrplay3/init.py", line 24, in
from .sdrplay3_python import *
ImportError: libgnuradio-sdrplay3.so.3.11.0git: cannot open shared object file: No such file or directory

Here's the output of the sudo make install:

Maybe the repository version of gnuradio is not the 'main' branch?

Thank you

Thanks @BobSelf22 for reporting this issue.

Do you mind running this command to see if it fixes the error cannot open shared object file: No such file or directory?

sudo ldconfig

If the error is still there, could you run this command:

ldd /usr/local/lib/aarch64-linux-gnu/libgnuradio-sdrplay3.so.v3.11-compat-xxx-xunknown

and let me know if there's any not found line for the shared libraries it depends on?

Thanks,
Franco

Yes that fixed it. I thought about doing that during the process, but forgot to.
So, now the rspdx is running on on the pi and playing audio.

Thanks!
