Good Morning!
I've just tried
QElectroTech_0.100.0-r7986-x86_64.AppImage
and
QElectroTech_0.100.0-r7989-x86_64.AppImage
They do not start at all on my system.
QElectroTech_0.100.0-r7981-x86_64.AppImage
did start, but with the described crash. (all other program functions worked perfect
As an linuxuser with limited expirience I tried to solve the problem on my site to start the newest build. Maybe for other, this may be usefull.
Starting on command line:
./QElectroTech_0.100.0-r7989-x86_64.AppImage
gave me errors.
./qelectrotech: /lib/x86_64-linux-gnu/libstdc++.so.6: version `GLIBCXX_3.4.32' not found (required by ./qelectrotech
and some more.
strings /usr/lib/x86_64-linux-gnu/libstdc++.so.6 | grep GLIBCXX
showed me
........
GLIBCXX_3.4.27
GLIBCXX_3.4.28
GLIBCXX_DEBUG_MESSAGE_LENGTH
So up to GLIBCXX_3.4.32 was missing.
sudo apt-get install libstdc++6
alone didn't changed anything
So I've done
sudo apt-get install libstdc++6
AND -->TAB, showed me some available versions.
I've picked
sudo apt-get install libstdc++6-13-dbg
(the latest one)
And this did the magic for me.
So thank you scorpio810 for solving the issue so fast!!!!
