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
