I am having a 5444B and recently upgraded Fedora 34 -> 35.
For the upgrade I had to uninstall packages related to pico. PicoScope 6 worked with F34
I have started picolog-6.1.18-x86_64.AppImage as well as a freshly downloaded picolog-6.2.1-x86_64.AppImage.
In both cases I see a blank program form with caption PicoLog which disappears after less than a second.
I'm not sure if this will help but I had a similar error message concerning libpicoipp-1.3.0-4r121.x86_64 regarding libiomp5.so, when I was installing picoscope on F35. I worked round it by manually installing libpicoipp-1.3.0-4r29.x86_64.rpm an older one. The ones after this are missing libiomp5.so.
Maybe this will help you.
I gave picotech (6.14.54-4r6108) in the repository a new chance today, but failed again, libiomp5.so being missing.
I have followed the recent comment of A.P. (thanks !) trying to install an older version:
sudo dnf install libpicoipp-1.3.0-4r29.x86_64.rpm
Can not load RPM file: libpicoipp-1.3.0-4r29.x86_64.rpm.
sudo dnf install libpicoipp-1.3.0-4r29.x86_64
worked neither.
By the way:
Although the 5444B not being a logger, I have run picolog-6.2.2-x86_64.AppImage and this works with the Scope , the earlier versions picolog-6.2.1-x86_64.AppImage and picolog-6.1.18-x86_64.AppImage did not.
Basically it works with an Appimage under F35, hope that there will be an Picotech Appimage too soon !
I also had trouble installing picoscope on my F35 box due to incompatible version of mono. However I managed to get it working for my 2204A with picomono using the following steps.
@Flinus: Many thanks for your comprehensive description !
In the meantime I have installed PicoScope 7 T&M Early Access Version 7.0.94.10729 (driver version PS5000A Linux Driver, 2.1.83.3073) for my PicoScope 5444B on Fedora 35
and thinks works for me, not having tested all features.
