Sorry I didn't mention it, but yes I tried the tgz first and it didn't start.
Once extracted, starting XnView from the terminal gives this message :
/usr/lib64/libQt5Network.so.5: version `Qt_5_PRIVATE_API' not found (required by ./XnView)
I checked and I have libQt5Network5 installed but I guess it's different since it doesn't have the ".so.5" (and the same goes for Core5).
Also I just tried the tgz on Manjaro and Kubuntu and got this message :
- Code: Select all
This application failed to start because it could not find or load the Qt platform plugin "xcb"
Reinstalling the application may fix this problem.
Aborted (core dumped)
Although on Manjaro I could install it from the AUR and on Kubuntu I could use the .deb package. But for OpenSUSE ? I didn't find a solution.
