libKF5Parts SO Undefined Symbol Arch

Question

When starting programs such as Okulus and Dolphin I get the following error:

symbol lookup error: /usr/lib/libKF5Parts.so.5: undefined symbol: _ZN3KIO18CommandLauncherJobC1ERK7QStringRK11QStringListP7QObject

Googling this suggested it may be a QT5 installation issue so I've reinstalled qt5-base and qt5.

Looking in /usr/lib for this file, I can see the library and its symlinks with what appear to be the correct permissions.

james@dev-box  ~  ls -la /usr/lib/KF5Par

lrwxrwxrwx 1 root root 16 May 3 10:07 /usr/lib/libKF5Parts.so -> libKF5Parts.so.5

lrwxrwxrwx 1 root root 21 May 3 10:07 /usr/lib/libKF5Parts.so.5 -> libKF5Parts.so.5.70.0

-rwxr-xr-x 1 root root 476944 May 3 10:07 /usr/lib/libKF5Parts.so.5.70.0

What else can I look at to fix this issue?

I had the same issue, I had to modify the PKGBUILD of the packages solid-git and kcodecs-git, on the line 'source', I replaced "git://" by "git+https://"

I use yay, I did :

And modify the line source :

source=('git://anongit.kde.org/solid.git')

by :

source=('git+https://anongit.kde.org/solid.git')

Quit the editor, and it should works.

I did it again with the kcodecs-git package

Right now, it should be OK for the solid-git package because I edit it, but we need to wait for the maintainer of the package kcodecs-git, or you can do it manually as explained.
