Apparently it's a missing Qt dll file, qwindows.dll, that also prevents it from running on Windows 10. I added that dll into a new package, but I couldn't test it on Windows 8. Could I please ask you to try it out on your platform to confirm that it also works? I attach the zip containing the missing library. Thanks again!

I wrote application for linux which uses Qt5.
But when I am trying to launch it on the linux without Qt SDK installed, the output in console is:
How can I fix this? Maybe I need to copy some plugin file? When I use Ubuntu with Qt5 installed, but I rename Qt directory, the same problem occurs. So, it uses some file from qt directory..
I have found file Zanna
libqxcb.so in the Qt SDK directory, but placing it in /usr/lib does not help.

The correct solution is running the following comand onto a terminal:
sudo ln -sf /usr/lib/x86_64-linux-gnu/qt5/plugins/platforms/ /usr/bin/
It creates the symbolic link it's missed.

To any future readers who come across this - before you start (dangerously) messing around with symlinks to shared libraries, I strongly suggest that you run
export QT_DEBUG_PLUGINS=1 Ni massive torrent mac 1.4.
and then run your failing executable again in the Terminal. Read the actual error message thrown by QT, since none of the above solutions addressed the cause of this error in my case.
My output after turning on
QT_DEBUG_PLUGINS was:
so I then googled the
version `ZLIB_1.2.9' not found (required by /usr/lib/x86_64-linux-gnu/libpng16.so.16)) error and found the solution to that, which solved the problem. https://oitjlbr.weebly.com/astral-projection-trust-in-trance-torrent-download.html.

Try to install
libqt5x11extras5 package with command:sudo apt-get install libqt5x11extras5
The name may be different. You can figure it out by searching:
sudo apt-cache search qt5 | grep 'X11 extras'
and u get the name of the package as result:
libqt5x11extras5 - Qt 5 X11 extras

I had this error message when trying to run 'Stellarium'.
With strace I found that the missing file was
libxcb-xinerama.so.0 .I had to reinstall libxcb-xinerama0 to make it work:

Run ldd on your application executable to see how it resolves library dependencies.

For those who are still stuck after trying every other option out there in the internet, you can look into exact path from which this notorious
libqxcb.so is being searched in, for opening/loading by the Qt App(VirtualBox-5.2.8 is the Qt app in my case), using the strace tool. In my case, since I was building VirtualBox-5.2.8 from its source, it was searching for libqxcb.so in the below location :'..VirtualBox-5.2.8/out/linux.amd64/release/bin/platforms/' and not in the default library paths, Qt installation path, etc. So, none of the ldd checks, and other solutions worked. And also setting QT_DEBUG_PLUGINS=1 didn't produce any extra logs either.
Running strace on the the VirtualBox binary I built using Clang/LLVM on Ubuntu 17.10 x86_64: https://oitjlbr.weebly.com/free-sims-2-hacked-objects-downloads.html.
That was my
hitting-the-nail-on-its-head moment, and I created the symlink from the installed Qt5.10.1 's platforms directory mentioned below :'..Qt5.10.1/Tools/QtCreator/lib/Qt/plugins/platforms/' onto the searched path which is '..VirtualBox-5.2.8/out/linux.amd64/release/bin/' . Thus, VirtualBox-5.2.8 built from source on Linux(Ubuntu 17.10 x86_64 ) using Clang/LLVM , finally launched successfully!
In fact, another interesting thing here is that, I have built
VirtualBox-5.2.8 entirely using Clang/Clang++/LLVM on Ubuntu 17.10 x86_64 after substantial effort - for FreeBSD , there's already a port for building VirtualBox using clang but for Linux, it's heavily dependent on GCC as I saw and hence it took a lot of effort to get to this point to be able successfully build VirtualBox-5.2.8 from its source using Clang/Clang++/LLVM on Ubuntu 17.10 x86_64 for target Linux/AMD64 (Ubuntu 17.10 x86_64 ) and successfully launch it after resolving other issues along with this notorious libqxcb.so one.
Cheers.

It seems there can be various different things missing behind this.In my case (Debian 9.7), QT_DEBUG_PLUGINS=1 did help to trace back the missing libraries, and
$ sudo apt-get install libxcb-render-util0 libxcb-image0 libxcb-keysyms1 libxcb-icccm4
solved the problem.
