[Buildroot] qt-webkit-kiosk on Raspberry Pi

[Buildroot] qt-webkit-kiosk on Raspberry Pi

[Michael Toldo]

Hi,

I just tried to compile the master buildroot for the Raspberry Pi 0 W.
Everything worked well an I was able to boot the image. I wanted to start
the qt-webkit-kiosk but this error occured:






*qt.qpa.plugin: Could not find the Qt platform plugin "eglfs" in ""This
application failed to start because no Qt platform plugin could be
initialized. Reinstalling the application may fix this problem.Available
platform plugins are: linuxfb, minimal, offscreen, vnc.Aborted*

The .config tells me "*eglfs backend available if OpenGL and EGL are
enabled*" but I guess OpenGL and EGL is already supported by the
rpi-userland.

Can somebody please give me a hint?

Regards

Seems your have set BR2_PACKAGE_QT5BASE_DEFAULT_QPA=eglfs without
setting BR2_PACKAGE_QT5BASE_EGLFS=y (maybe disabled because of
missing dependencies)? Or you need to do a complete re-build
(after changing some options, see [1])?

Mind to share your .config file?

Regards,
Peter
