Messed up qt5 installation

palmighty · 2021-04-26 14:27:50

Hi, I had everything running as it should before, but the other day I installed qt6 and qtcreator to do a project, and now it seems I messed up qt somehow. After a restart, no qt gui apps would open. Specifically qjackctl wont open with a message:

qjackctl: symbol lookup error: /usr/lib/libQt6Core.so.6: undefined symbol: ucal_getDefaultTimeZone_69

VLC, and any other qt interface won't work either. I tried deleting everything: Both qt5, qt6, qtcreator and qjackctl, and let it install it's own dependencies by itself, but still it won't run with the same error. It's obviously missing something, or it's a .so version mismatch. Does anyone know how to fix this?

What does this mean exactly? What did you actually do (what commands)? What is "it" in this sentence?

Please post your complete pacman.log in code tags.

I'm so sorry for being vague. I really need some help with this, It's been keeping me from work a whole day.
(full log at the end)I uninstalled it with

pacman -Rsnd --nodeps qt5 qt6

as well as

pacman -R qjackctl.

Then I did

pacman -S qjackctl

which installed qt6 as a dependency.
It still did not work. I also tried installing qt6 by itself (not as a dependancy, but still no qt app would open). Below is the log. Starting from line 4324 I uninstalled everything regarding qt and reinstalled.

Post the output of

ls -l /usr/lib/libicu*

You are doing partial updates. Stop doing that, run a full pacman -Syu : https://wiki.archlinux.org/index.php/Sy … nsupported

No, it's even worse: they're symlinking different library soversions. Remove all the manual symlinks you created and update your system properly, and don't do such thing again.

Thanks for the help!
So the fact that I upgraded to qt6 without doing a full system upgrade was wrong? (qt6 upgraded it's dependencies , breaking other packages?) is that correct?
Now I am to remove just icu symlinks or something else aswell?

No, installing qt6 without doing a full system upgrade shouldn't be a problem, unless you had done a 'pacman -Sy' before - which, given the outcome, I assume you did and then tried to fix the mess by creating symlinks which ended up completely breaking your system.

palmighty · 2021-04-26 17:07:36

I understand, thanks. Though I didn't create the symlinks myself, but installed icu from aur, since there was an error regarding missing icu libraries. But that's a problem for another time. I will do what you said.

arojas · 2021-04-26 17:19:05

/usr/lib/libicuuc.so.69 -> libicuuc.so.68.2

If this symlink was created by an AUR package, please report it ASAP so it can be deleted, this is *extremely* wrong.

I will try to look into it. If someone else has time to inspect it, the package was just 'icu'.
