[Pkg-kde-extras] Bug#902118: quassel-core: quasselcore unable to load installed libQt5Core.so.5

[Jan Christoph Terasa]

Package: quassel-core
Version: 1:0.12.5-2
Severity: important

Dear Maintainer,

I am unable to start the quasselcore systemd service unit. Manually starting
quasselcore results in:

$ sudo -u quasselcore quasselcore
quasselcore: error while loading shared libraries: libQt5Core.so.5: cannot open shared object file: No such file or directory


If I comment the systemd-option Restart=on-failure in the provided quasselcore.service
file, I can see the same issue via systemd (otherwise systemd will complain
about too many restart tries):

$ sudo systemctl status quasselcore

LibQt5Core.so.5 is installed, though:

$ sudo updatedb && locate libQt5Core.so.5 | xargs ls -l
lrwxrwxrwx 1 root root      20 May 20 23:57 /usr/lib/x86_64-linux-gnu/libQt5Core.so.5 -> libQt5Core.so.5.10.1

-rw-r--r-- 1 root root 5224752 May 20 23:57 /usr/lib/x86_64-linux-gnu/libQt5Core.so.5.10.1


ldd reports the binary cannot find libQt5Core.so.5, but other Qt5 libraries are
found:

Running ldconfig, or setting LD_LIBRARY_PATH does not help, either:

$ sudo -u quasselcore LD_LIBRARY_PATH=/usr/lib/x86_64-linux-gnu quasselcore
quasselcore: error while loading shared libraries: libQt5Core.so.5: cannot open shared object file: No such file or directory


Upstream offers a version of the quassel-core, which is statically linked
against Qt, so testing that does not make much sense. I have not tried to build
quassel-core from source myself.



kind regards,
Christoph Terasa
