Qt platform plugin "xcb" error
-
Hi, I get this error when I execute program: This application failed to start because it could not find or load the Qt platform plugin "xcb".
Available platform plugins are: eglfs, linuxfb, minimal, minimalegl, offscreen, wayland-brcm, wayland-egl, wayland, xcb.
Reinstalling the application may fix this problem.
AbortedHow to fix this issue? I have everything in folder what that program needed.
Here is package: https://onedrive.live.com/redir?resid=AB8B24AE3D535ECC!2470Regards, Niko H.

Hi,
How are you trying to deploy an application that you compiled yourself? If so, you are probably missing a shared library.
Follow the quick-and-dirty guide here to find it: http://qt-project.org/wiki/Deploy_an_Application_on_Windows (it's written for Windows bus also works on Linux -- just replace *.dll files with *.so files)
-
Hi,
Do you have all dependencies properly installed on your target computer ? Check running ldd on the xcb plugin

Hi,
I found how to install libxkbcommon. But now I get next error:
Linux system - locale: "English"
Cant find EGLConfig, returning null config
Unable to find an X11 visual which matches EGL config 0
QXcbConnection: XCB error: 165 (Unknown), sequence: 149, resource id: 0, major code: 149 (Unknown), minor code: 20How fix this?
Regards, Niko H.

I don't know, sorry. It looks like an issue with your Linux filesystem, not just Qt -- I think you'll have better luck if ask devs who have Raspberry Pi experience. See http://www.raspberrypi.org/phpBB3/viewtopic.php?t=35099
EDIT: You can reach people in the "Qt on Pi" project at http://qt-project.org/wiki/QtonPi-Collaborate

I've tried on installing the dependencies you have suggested installing using the apt-get command. Unfortunately that doesn't work. I'm not using raspbian at the moment, I'm trying to install the qt5 onto my ubuntu 10. I've read it is possible to develop App on ubuntu and after compilation move it to the raspbian using the cross-compiling technique.

ok... now I receive an error when I try to launch qtcreator... it seems the "libCore.so" is missing! How can I check if it is properly installed? What do I have to do to install it?

I have tried on installing Qt5 from git repository, I have followed the instruction guide described "here":http://qt-project.org/wiki/Building_Qt_5_from_Git and and when I make Qt using the command "make -j4 all" (I have tried both the command) I received the error bellow:
@collect2: ld returned 1 exit status
make[6]: *** [../../../../plugins/platforms/libqxcb.so] Error 1
make[6]: Leaving directory/root/opt/qt5/qtbase/src/plugins/platforms/xcb' make[5]: *** [sub-xcb-plugin-pro-all-ordered] Error 2 make[5]: Leaving directory/root/opt/qt5/qtbase/src/plugins/platforms/xcb'
