You're not xing qt4 and qt5 in the same process. One possibility is that you're still linking the qt4 of those qtsingleapplication and/or qxt system libs

[Rex Dieter (rdieter)]

Yay phone . s/not xing/mixing/

[martinkg (martin-gansser-c)]

I 've build it with the following rpm spec file, but w/o success.
https://martinkg.fedorapeople.org/Packages/yarock-1.1.4-qt5.spec

any idea ?

[Rex Dieter (rdieter)]

Yes, at least drop -DUSE_SYSTEM_QXT:BOOL=ON (the version you're using here is still qt4)

[martinkg (martin-gansser-c)]

no success with the mentioned rpm spec file. :-(
