Fedora 31 - /XnView: /lib64/libQt5Network.so.5: version `Qt_5_PRIVATE_API' not found (required by ./XnView)

[ivnmad]

Hi, I've just upgraded to Fedora 31.
I initially had an error for a missing library.
After installing that, I started getting the following error:

./XnView
./XnView: /lib64/libQt5Network.so.5: version `Qt_5_PRIVATE_API' not found (required by ./XnView)

That's where I'm currently stuck, also because I have no clue on how to get around that.

Thank you,

Ivan

you can't use QT libs in the package?

Hi Pierre,

I cannot use the QT libs provided by creating links in /lib64 because those libs already exist.
I cannot remove the packages qt5-qtbase + qt5-common (and their libraries), because they are used by other applications.

If there is way to tell XnView MP to use /opt/XnView/lib instead of the system libs, then it might work.
If the above is already in place (i doubt it, since the error message references the lib in the system folder), then I'm not sure what else to do.

The file qt.conf shows:

[Paths]
Plugins = lib/plugins
lib = lib

I hope that helps somehow.

Thank you,

Ivan

please check the xnview.sh

Hi Pierre,

OK, I forgot about xnview.sh and was using the Xnview file directly.
Anyway, xnview.sh worked after I added the following link in the lib folder:

sudo ln -s /lib64/libbz2.so.1 libbz2.so.1.0

Without that Xnview was complaining:

/opt/XnView/XnView: error while loading shared libraries: libbz2.so.1.0: cannot open shared object file: No such file or directory

Thank you,

Ivan
