<![CDATA[Beaglebone Black - touch screen project]]>Hello everybody,

I am using Qt Creator on my virtual machine (Ubuntu 12.04.5 LTS), and Beaglebone black with touch screen. When i write gui application(only one window with push button) and try to deploy it, i get this error :

This application failed to start because it could not find or load the Qt platform plugin "xcb"
Reinstalling the application may fix this problem.
bash: line 1: 907 Aborted DISPLAY=':0.0' /opt/proba/Test/Test
Application finished with exit code 134.

I was searching on the internet and found that this problem i somehow related to libqxcb.so library, i tried ldd libxcb.so command and result is :

linux-vdso.so.1 (0xbef5a000)
libQt5XcbQpa.so.5 => not found
libdl.so.2 => /lib/arm-linux-gnueabihf/libdl.so.2 (0xb6f67000)

libxcb-randr.so.0 => /usr/lib/arm-linux-gnueabihf/libxcb-randr.so.0 (0xb6e44000)

etc...

As you can see, libQt5XcbQpa.so.5 is not found, even though this library exists in:

-rw------- 1 debian debian 1140 Feb 9 2016 libQt5XcbQpa.la
-rw------- 1 debian debian 1478 Feb 9 2016 libQt5XcbQpa.prl
lrwxrwxrwx 1 debian debian 21 Mar 1 12:34 libQt5XcbQpa.so -> libQt5XcbQpa.so.5.5.1
lrwxrwxrwx 1 debian debian 21 Mar 1 12:34 libQt5XcbQpa.so.5 -> libQt5XcbQpa.so.5.5.1

-rw------- 1 debian debian 602768 Feb 9 2016 libQt5XcbQpa.so.5.5.1
