Description Markus 2018-02-02 22:57:26 UTC
Current (=12c4d9ec3437469ccfca23d35ba6258d55bbedb6) qt overlay breaks qt-5.10.
Programs fail with 'This application failed to start because it could not find or load the Qt platform plugin ""in "".'
sddm is just a black screen.

Rebuilding whole qt does not fix it.


Reverting overlay to last week (=d53ea392ebed74e67e7d46ac19060fc4d43bd29b) works again.

This may be fixed by adding -gui and -widgets to qtgui/qtwidgets src_configure respectively, but I'm not able to do a runtime test yet.

    dev-qt/qtwidgets: enable widgets
    
    Since e553539e7ee050d094da9a4673b2e5ac71aae422, we started passing -no-widgets
    so we need to start explicitly enabling it here.

Comment 3 Michael Palimaka (kensington) gentoo-dev 2018-02-03 03:59:42 UTC
Thanks for the report and investigation.

I was able to reproduce with 5.9 too and have pushed a fix that works for me.
Comment 4 Markus 2018-02-03 07:17:57 UTC
Is working here for 5.10 as well.
Thank you!
