Book conversion to .mobi uses Qt5 broken plugin undefined symbol: _ZN20QPlatformIntegration11screenAddedEP15QPlatformScreen Simple solution. Just need rebuild
Which plugin? Adding Rex here for qt5 perspective... ;)
This one: /usr/lib64/calibre/calibre/plugins/libheadless.so I just recompiled the master branch, .20, on f21 and everything is fine. So, confirming, need only recompile. []'s
I have the same issue with calibre-2.15.0-2.fc21.x86_64. I can't convert epub to mobi, it says: python2: symbol lookup error: /usr/lib64/calibre/calibre/plugins/libheadless.so: undefined symbol: _ZN20QPlatformIntegration11screenAddedEP15QPlatformScreen
I have recompiled calibre from the f21 branch (just `fedpkg mockbuild`) and it did not fix the problem for me, it's still the same. Maybe I'm missing some step?
