I'm running fldigi 4.2.05.24 on a RaspberryPi4 on Raspbian 10 buster. The station runs 24/7 and several times a week when I remote in to the Pi I find fldigi is no longer running.

This evening I was actually looking at the display when it happened. I had entered a command, and it timed out dues to open squelch, reported that in the receive pan then immediately aborted.

Anything I can look for to help troubleshot this issue?

Hi Rick

.xsession-errors in the home directory usually contains the terminal output of any application errors. The other possibility being run fldigi from a terminal.

A look at the journal or syslog plus dmesg may also contain some clues. ie things that happened at the same time the program died.

Also possible to run fldigi from the debugger. Would be a good idea to build to the latest version first though. Buster is getting a bit old too.

?Rick,
I also use fldigi 4.2.05 on a Pi4 using Buster. My system was stable for until I started using flmsg. With it running, fldigi would freeze every few days. Without it, I can operate two simultaneous instantiations of fldigi (FSQ and Thor) for weeks without problems.

Same problem here with Debian 12 and fldigi 4.1.23 (latest in the mainline repository).? Locks up every few days with high CPU utilization.

?

It's the program, rather than some RFI or other environmental.?? Been there, have the t-shirt.? Too predictable for that, plus the OS and other programs run rock solid.

My guess is a Pipewire incompatibility as mentioned.? Will be checking out the potential flmsg connection.

Thanks Dave, I will try the debugger.
I just did a new install on my new install of Linux Cinnamon Mint 22 using the WIKI. I followed the console and couldn't see what version of fltk it was installing.
Here's some notes I'm not sure about when I do the build:

****

sudo aptitude build-dep fldigi fails...

ny3j@ny3j-NucBox-G3:~$ sudo aptitude build-dep fldigi
Unable to satisfy the build-depends: Build-Depends: debhelper-compat (= 12)
Unable to apply some actions, aborting

so I continue to do sudo apt-get

sudo apt-get update
sudo apt-get build-dep fldigi

When I do the sudo aptitude install pavucontrol command I get the following:

Pipewire is supposed to emulate the API calls for pulseaudio.? I do not think that pavucontrol is compatible with pipewire.

When working with PipeWire, you can use audio mixer controls like "qpwgraph" (a Qt-based graphical patchbay), "Helvum" (a GTK-based patchbay), or Carla (a JACK-based mixer) to manage your audio routing and mixing, depending on your preferred interface and complexity needs; for more advanced audio processing, consider using dedicated plugins within your DAW or applications that support PipeWire integration.
Key points about these options:

??? qpwgraph:
??? Considered one of the most popular choices due to its user-friendly interface and Qt framework, offering a visual representation of your audio connections within PipeWire.
??? Helvum:
??? A GTK-based patchbay that provides a similar functionality to qpwgraph, with a slightly different interface.
??? Carla:
??? While primarily a JACK-based mixer, it can be used with PipeWire through the JACK protocol, allowing for more complex audio processing and plugin integration.

Thanks David,

So I installed qpwgraph and when I run it I see a graphical display but I don't see any slider bars to adjust audio. I can see pipewire in my pulse audio volume control application so is it okay to use that? Here's what it looks like:



Also, in Fldigi sound card configuration do I need to select PortAudio, pipewire for my Devices?

If you are using Pipewire as the audio controller then simple check "PulseAudio" on the fldigi Soundcard/Devices dialog tab.

Sounds good. Just like I've always had it. It just confused me a little because I'm hearing from the tech world that pipewire is the replacement for pulseaudio so I thought we would have to change the configuration from pulseaudio to portaudio using pipewire. It's a challenge keeping all of this straight LOL.
