Hi Stefan,
there is linuxdeployqt, but it seems to have a couple of issues. With
the plugins, one would either need to copy all the plugins from the
build machine, or have a curated list of plugins required for the
application to work. No tool can possibly infer plugin dependencies
without knowledge of the source code or runtime behavior.
Best,
Sascha

Hi Sascha,
you're right. It wasn't intended not to ship the Qt plugins within the package.
I'll check that and update the tarball. BTW, do you know something similar for
Linux like windeployqt.exe?
Best,
Stefan

Subject: [mitk-users] Linux package contains Qt libraries but no plugins
Hi,
I just tried the MITK 2016.11 Linux binary (I have a MR dicom series to
view) and got the (kind of) common error:
This application failed to start because it could not find or load the Qt platform plugin
"xcb"
in "".
Reinstalling the application may fix this problem.
which is typically attributed to the Qt plugins not being found. Looking at the
bin folder, I saw that the Qt libraries are shipped in the binary package, but
not the required Qt plugins. Is there a particular reason for that?
In my view, you should either ship a complete self-contained set of Qt
libraries, or none at all. After I deleted all bin/libQt5* files, my system Qt
libraries were used by the MITK Workbench and hence also the system Qt plugins
were found and loaded (sure, some QT_PLUGIN_PATH env var trickery would also
work, but just hides the real issue). The workbench started just fine.
Let me know if I can help with this for the next release.
Thanks,
Sascha
