Hi Aurélien,
I'm by NO means intending to unintentionally diminish your qt5 work.
All I'm saying is: Qt5.8 is simply too new in every aspect.
It needs to be migrated in carefully and in paralel to good old stable 4.8
As promised I now wanted to port vbox5 back to Qt5 and run a test compile against your bins.
This showed me 2 things:
First of all it simply isn't a good fit yet, if the Qt5 version is above Qt5.6.
Secondly my host is too old (and if it wasn't, then most test users' host would be and then their tests would have failed).
I didn't even come to any point close to getting Vbox linked against your bins so I cannot even say, if it would actually work now or still crash at start with
> with all I would get was: "gtk_menu_attach_to_widget(): menu already
> attached to GtkMenuItem"
... as it did with the Qt5.8 bins I built myself over last week.
But even now without the final confirmation I can say: Oracle Vbox is not yet by default compatible to 5.6 or higher - that's a fact.
Here the individual dilemmata:
#0.)
During ./configure of Vbox5 in the checks for Qt5 it requires the same CFLAGS/CXXFLAGS as Qt5.6 or higher does: -std=gnu++11
BUT as soon as Vbox compile runs for 1 or 2 minutes, it encounters the first (of hundred) points where -std=gnu++11 BREAKS the Vbox5 compile.
#1.) My host is too old and there I ran into such situations again where I in the past shouted I HATE IPS.
Your Qt5 is linked against several (!) libs that are not yet available on my machine in the matching version.
But there is no -f or -ignore-ips-insanity option to get these bits installed here without perhaps some full upgrade (still didn't ever check if that really works).
I could work around that for some time with symlinks, but after all it failed because the linked in versions also get checked during linkage, but don't match.
Then I attempted to install the missing bits (here only one example), but IPS's dictatorship mode never lets me.

So _if_ we want to use Qt5 for anything, then not a version newer than 5.5.
And then you might say again, that it is a waste of time to deal with such "old" Qt5 version (5.5) and that this would require us to re-invent the wheel later on.
And this version is btw the last one which on my setup does not yet run into the other problem: http://stackoverflow.com/questions/38549755/raspberry-pi-2-and-qt-5-7-make-stuck-at-qtbase-bin-qmake-conf-qtbase-q
In the best interest of the stability of Oi it is best to use the Qt4 Vbox5, as many user feedback messages have shown.
BTW, the trick provided by Christian Meier to get Vbox5 running as root *WORKS* and *VOILA*, suddenly usb devices (of the real host) do get listed for attachment :-)
No network cable or anything is needed, just locally:
A) ssh -X localhost
and then
B) su (without -)
C) /opt/VirtualBox/VirtualBox
And bingo! USB devices are suddenly all there and also non-USB passthrough works as root!
This is required to install copy-protected optical media to MS-Win guests, such as in my case the Russian Language learning software requiring not only a vendor's genuine serial number but also running authentication checks against the physical (!!!) DVD itself.
Big thanks to longterm OpenSXCE community member/supporter and now Hipster co-migrant Christian Meier https://openindiana.org/pipermail/openindiana-discuss/2016-September/019544.html !!!
Thanks also to all others who tested and reported, including now also tnx to Mr. Carl Brewer https://openindiana.org/pipermail/openindiana-discuss/2016-September/019560.html
