Remote debug error (This application failed to start because it could not find or load the Qt platform plugin "xcb" in "")

[adrianomunin.eld]

Hello,
I’m currently working with Qt Creator to develop a graphical interface using Embedded Linux and Qt. The interface is runing on a Toradex device powered by an IMX6 processor using BSP 2.8.
The initialization of my Human-Machine Interface (HMI) works seamlessly through systemd. However, an issue arises when I attempt to launch it via SSH from its designated directory (/usr/bin/IHM). I’m confronted with the following error message:

This application failed to start because it could not find or load the Qt platform plugin "xcb"
in "".

Available platform plugins are: eglfs, minimal, minimalegl, offscreen, vnc.

Reinstalling the application may fix this problem.
Aborted (core dumped)

I encounter the same error when I try to debug the HMI using Qt Creator. The connection to the board appears to be established without any evident errors. Bellow are Qt Creator logs:

Starting /opt/IHM/bin/IHM...

QML debugging is enabled. Only use this in a safe environment.
This application failed to start because it could not find or load the Qt platform plugin "xcb"
in "".

Available platform plugins are: eglfs, minimal, minimalegl, offscreen, vnc.

Reinstalling the application may fix this problem.
Process killed by signal

Configurations:

Could you please assist me in identifying the error with remote debugging of the board?

Best Regards,

Hello @adrianomunin.eld ,

There are some plugins already available on your module, for better performance we recommend using the eglfs plugin. To select this plugin you will need to configure the QT_QPA_PLATFORM environment variable, you can do this on both QT Creator and userspace side. For more information please verify this article.
