Mooneer, 

Below, is the  output below I got attempting running 2.2.1 on OpenSuSE Tumbleweed and it's still immedietiately "closing" shortly after the "Start Modem" is initiated.

I am guessing this the similar to the output I got before with 2.2.0

And as before, It runs flawlessly on Ubuntu based KDE Neon (on a Mid 2012 Macbook Pro)

[Rick Kunath]

Appimage or source built Rick?

I source built a git clone earlier and it runs fine on Tumbleweed.

Could this be a Python issue? Venv or environment variable?

Hi Rick, 

It was the downloadable AppImage.  

After 25 years of using OpenSuse, I suppose it's finally time to learn how to install a program from "Source"!!!

[Rick Kunath]

I’d be happy to give you a hand.

FreeDV is fairly involved with a lot of steps, but you’ll feel comfortable when you see the process.

Are you at Python version 3.13?

[Rick, W4XA]

Looks like it:

Version:

3.13.11-1.2

Provides:

libpython3.13.so.1.0()(64bit)
libpython3_13-1_0 = 3.13.11-1.2
libpython3_13-1_0(x86-64) = 3.13.11-1.2

[Rick, W4XA]

But if I build from source, don't I have to do it again if Tumbleweed is updated either via Discover, "zpper dup", or Yast?

[Rick, W4XA]

I think I posted the wrong one!

Installed Version

3.13.11-1.1

python3-readline
python3-sqlite3
python313-readline
python313-sqlite3
python3 = 3.13
python313 = 3.13.11-1.1
python313(x86-64) = 3.13.11-1.1

[Mooneer Salem]

Hi Rick,

Re: AppImage--any difference if you do the following from a terminal?

./FreeDV-2.2.1-x86_64.AppImage --appimage-extract

./squashfs-root/AppRun.sh

If not, just to make sure--what Python version shows up if you run ./squashfs-root/usr/bin/python3?

Thanks,

-Mooneer K6AQ

[Rick Kunath]

3.13 is the latest Python version Tumbleweed has and the one I built
against.

I have never needed to rebuild FreeDV when there was an update. Of
course in the case of major lib changes you might have to. It's trivial
to do if ever needed though.

As to updating, on Tumbleweed you should only ever update via the zypper
dup command. Using YaST or Discover will leave you with a broken system.

YaST or Discover can only ever be used to update a system on one of the
Leap point update releases, never Tumbleweed (rolling release).

However, using YaST is encouraged for adding packages and libs or
switching app or lib versions int he case of having some repos
configured that are supplying beta or git versions of software or libs.
