Calibre (beta) GUIs will not run -- wrong version of glibc?

All GUI windows are broken like this. Using source (fully updated):

Where is /opt/calibre/lib/libstdc++.so.6 coming from, it is not part of the official tarball. Try deleting /opt/calibre and re-installing.

[eschwartz]

I have no idea , but that worked.

I have never done anything other than unzip official tarballs there. Or install via the official script.

...

It seems to be in the Qt4 main binaries, and I unzipped the beta without clearing /opt/calibre/

[kovidgoyal]

Yeah it was removed from the Qt 5 tarballs because the QPA infrastructure requires the system libstdc++ to be used. https://github.com/kovidgoyal/calibr...freeze2.py#L93

[eschwartz]

Mystery solved!

Lesson learned -- wipe /opt/calibre before manually extracting stuff. I assume the installer does this already.

We need a beta install script.

[kovidgoyal]

Yes, the installer does it already.
