Hi,
I am in the process of upgrading to Qt 5.7.1 . While porting my Qt5 patches and
building was largely a no-brainer and most applications seem to work without
issues, there are (at least) 2 annoying exceptions among basic KF5 apps:
- kded5 deadloops somewhere
- kbuildsysoca5 idem.
In addition, my KDevelop 4.7 install that works fine when I have Qt 5.6.2
active now crashes randomly because of an illegal operation *in a Mac SDK
library*. That doesn't seem to make sense, yet it's reproducible.
On Mac we might be able to do without kded5, but I don't think we can do
without kbuildsycoca5 .
My analoguous Linux build isn't finished yet so I cannot say whether this is
Mac-specific or something that may have to do with the way I install things.
Does anyone have any suggestion where I might start looking? I already tried to
run under lldb, interrupt once the deadloop was clearly installed and try to
step out of functions to get an idea of that loop. Didn't really work; at some
point lldb just stops co-operating ("error: Couldn't find thread plan to
implement step type.").
There is a difference between 5.6.2 and 5.7.1 in the native QStandardPaths
locations that are returned. I don't use those for writing, but if for instance
kbuildsysoca5 parses everything under the GenericCacheLocation it will now have
to wade through over 3.5Gb of crud, and that would of course take "a bit" more
time.
Thanks...
R.
