Hello!
I’d like to run the “microelectronics” from the shared Geant4 examples from the docker container. After cmake and make I have an executable file in the build directory, however, when I run it, it returns the error:
/home/geant4/microelectronics/microelectronics_build# ./microelectronics
Available UI session types: [ Qt, tcsh, csh ]
qt.qpa.xcb: could not connect to display
qt.qpa.plugin: Could not load the Qt platform plugin "xcb" in "" even though it was found.
This application failed to start because no Qt platform plugin could be initialized. Reinstalling the application may fix this problem.
Available platform plugins are: eglfs, linuxfb, minimal, minimalegl, offscreen, vnc, xcb.
Aborted (core dumped)
Is it a problem with my current Qt installation outside the container? Please help to find the reason or provide me with another way of running it. Thanks!
The whole output is listed below:
