Description Rex Dieter 2018-06-08 19:55:55 UTC 
kirigami-5.47.0 fails to build on a rhel7.5 host using (default) gcc-4.8.5 compiler (against system Qt 5.9.2):

build log appended below.

I'm trying to build kde frameworks for epel7 addon repository for RHEL7.  I can probably use an alternative compiler (gcc7 with devtoolset-7), but I'd rather avoid that if possible.

Comment 1 Christoph Feck 2018-06-08 21:03:35 UTC 
probably needs some .data() to access the QPointer, at least that's what I remember from the older GCC 4.8.x on openSUSE fallouts.
