Hi René and Ian,

and the physicist (in me) also thinks that this is indeed a simple experiment. :)
[But a simple one which has proven to be already complicated enough.]

I tried to trigger that after the folks started to work on the "KF5 book” at Randa.
But there was no further response to my post [0] except the already mentioned post by David!
Cristian Onet from KMyMoney sent also a response to that thread, as he seems the same
need for the Windows platform.
I still think one should write a test application which would test all these different
aspects of locating the whole variety of files necessary at build and runtime.

I am sure that the KF5 book will contain some simple code examples. I guess it’s worth
checking it out, as quite some effort has been invested in it back then.

Well, see my other post. I did that already.

qt5 build just fine. Qt apps are running, as tested with QtLinguist.app.

qtpaths eventually shows all the XDG_*_DIRS paths correctly:

but of course bovo still fails miserably, which seems to be caused by the bovo porting bug which Ian
pointed out in another post earlier.

Now I am running the complete rebuild of whole KF5… (Which I probably wouldn’t have to, as the QSP
patch [1] is binary compatible, right?!)

Yep, that might be a good idea.

Well, that decision had to be made back then, as there were problems when stuff was in ~/.kde only…
Can’t remember what exactly it was though. But it was deliberately introduced.

Well, I need all these only for the OSX/CI system.

Yes, that’s why I also have to be careful with what I change on the CI system,
like in case of bovo’s theme location [2], which removes this from the 
darwin-mavericks platform configuration:

	-DDATA_INSTALL_DIR="Library/Application Support"
!!!

CMake and QSP have to be synchronised, that’s what was also underlined on K-F-D a couple
of times during this summer, i.e. every time when I tried to get help with my QSP patch.

	Luckily Ian’s post on KDE-MAC finally brought movement again!!! :)

Greets,
Marko

P.S.: I see already that building kconfigwidgets, kservice, kio, kinit, kdesignerplugin,
      and kded already failed and I do expect more to follow due a good old friend,
      namely their inability to locate

		kf5/kdoctools/customization

      which needs some rework on my end! But I really wonder why this happens, as the
      frameworks in question should be able to locate everything now natively since
      they’re aware of the XDG_*_DIRS vars after all.
