Hello Aurélien,

thanks for your understanding and for your qualified response.
Well, from vbox's viewpoint Qt.n (with n ==4.x or 5.x or z element N) is just a 
single of many related aspects.
It just has to perform its job.

On the other hand I certainly understand that Qt by itself is an amazing 
framework and that it can be someone's pet project in its own sense.
Certainly do ship Qt5 asap (and I give you back the hipster integration 64bit 
changes of your original diffs, just for having a look), software packages 
depending on it can slowly get used to it. And then at some future point decide 
to move over.
In my view it should perhaps be started with 5.5 because it is the last release 
that build without -std=c++11 (or compatible).
While the later releases not only require that, but also force its clients to 
be compiled the same way (via their default config scripts anyway).

For another round I'm now trying to test Qt5.5 for a last time together with 

/code/ALP__KMS_MATE__checkout20160911sun/oi-userland/components/qt5$ gmake 
clobber;gmake build
/bin/rm -f -r qt-everywhere-opensource-src-5.5.0 required-pkgs.mk 
/bin/rm -f -r 
/bin/rm -f -r qt-everywhere-opensource-src-5.5.0.tar.gz
/bin/rm -f -r 

But as said: Vbox has different complexities to consider.
Before release (rather than in a future upgrade) it is actually my goal to get 
these server oriented features compiled in, too:

  --enable-webservice      enable the webservice stuff
  --enable-vnc             enable the VNC server

And this intruduced additional dependencies, which also needed to get added: 
gsoap and libvnc.
So as you see, Qt4 works(T.M.) plus exists and is available for older 2015 
Hipster and I move on (except for a last Qt5.5 test which I will cancel unless 
it works smoothly in 24 hours).

And then of course there are all the other parts of my Hipster TODO list as 
mentioned 2 days ago.
Let completely alone that I now finally have to quit university (without Maths 
degree) and need to register as unemployed.
So - qt5 has exacvtly 24 hours or vbox5 takes 4.8 for now. It is only one small 
item in a huge puzzle. Things need to move on here  ...

Kind regards,
