image not portable(?) with Qt5 libs not found when running on some hosts

[Thomas Hartmann]

Hi all,

we see an odd issue, where a container seems not to be portable between
hosts.

The container is based on FC34 (tried CentOS7 as well) and only the
nextcloud-client is installed from the default repos. The builds seem
unssupicious on various hosts.
On my FC34 laptop, I can run the application without problems when
shelling into the resulting container image [1].
However, when trying the same on other hosts (CentOS7 etc.), the
application throws an error about missing its QT5 shared libraries [2]?!
Which is (nominally) nonsense as the library is present in the
container's namespace [2.b] and envvars are set in the instances paths.

Comparing the linked libraries [3] actually shows, that in the instance
on a CentOS7 host the library is actually not found - where on the same
container image on FC34 it is found/linked.

Maybe somebody has an idea what could be causing this strange behaviour?

Cheers and thanks,
Thomas
