Re: fosphor sink block

gr-fosphor works with 3.10. It looks like you built gr-fosphor from source when you had 3.9 installed, and then upgraded to 3.10. The gr-fosphor library is looking for the old gnuradio-runtime library. If this is the case, rebuild gr-fosphor under 3.10.

Hi,

 

5 months ago I was using GnuRadio 3.9 with the fosphor sink block.

I had some issues and some of you help me to fix it.

 

Today I restart GnuRadio. It indicate me that the version is : 3.10.2.0.

When I try to run my flowgraph : UHD:USRP Source à fosphor sink (Qt) I have the following error:

Generating: '/home/ghochet/Documents/Experimentations/CaracterisationEnvironnement/2022/08-06-2022/test_detect_wifigrc.py'
Executing: /usr/bin/python3 -u /home/ghochet/Documents/Experimentations/CaracterisationEnvironnement/2022/08-06-2022/test_detect_wifigrc.py

Traceback (most recent call last):
  File "/home/ghochet/Documents/Experimentations/CaracterisationEnvironnement/2022/08-06-2022/test_detect_wifigrc.py", line 28, in <module>
    from gnuradio import fosphor
  File "/usr/lib/python3/dist-packages/gnuradio/fosphor/__init__.py", line 9, in <module>
    from .fosphor_python import *
ImportError: libgnuradio-runtime.so.3.9.4: cannot open shared object file: No such file or directory

 

I try to install the package with apt-get but I have an error saying it does not exist.

 

Do you know how I can fix it ?

Or do you know a block having the same output of fosphor ? I appreciate it because I can see in real time if a signal is present or not.

I try using QT GUI Sink looking at the waterfall but this is not what I want. Same for the QT GUI Frequency Sink.

 

Thanks for your help,

Gwendoline
