Linux x11 is required even if I compile with QT -= gui and CONFIG += console

FrankE

I get this from a commandline tool I've made if I have no graphics device enabled (I can fake one but that's a bit tricky)

qt.qpa.xcb: could not connect to display
qt.qpa.plugin: Could not load the Qt platform plugin "xcb" in "/mproject/plugins/platforms:" 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, wayland-egl, wayland, wayland-xcomposite-egl, wayland-xcomposite-glx, xcb.

Any idea about what can I do? I'm worried about needed it due QT += widgets but unfortunately some functional classes like QVector3D are dependant on this.

Thank you in advance for any tip.

Hi,

Using the widgets module implies the gui module.

By the way QVector3D is in the gui module.

Are you using classes which requires a QApplication ? If not the just use a QCoreApplication.

If you need a QApplication then use the offscreen backend.
