Using this link I created a container and after getting some packages, I want to start a qtcreator 4.0.1 on it. I use a ssh connection to connect to the container. After launching qtcreator I get an error such as this:
This application failed to start because it could not find or load the Qt platform plugin "xcb"
in "".
Available platform plugins are: eglfs, linuxfb, minimal, minimalegl, offscreen, xcb.
Reinstalling the application may fix this problem.
I installed all prerequisites packages as listed here but still the problem is remained. I must mention that I am using a privileged container in opposite of the link.
xcb listed as available plug-ins but it does not run. Is there any suggestion to get around this bug?
This answer has the main solution. In my case I find the libqxcb.so in path /path_to_qt/plugins/platforms/ and after running ldd command on it I found that it has not one of its dependency libEGL.so after install this package using sudo apt install libegl-mesa0-dev I could run qtcreator.
