Yocto(imx-4.1.15-krogoth) : Render process exited with code 11 in qtwebengine

[bmoraine]

Hello,

I am trying to evaluate the performance of imx6Q on a imx6Quad sabre board when running qtwebengine examples but  neither webengine or webenginewidgets runs normally. In all cases, I face a render process error with a value of 11.

To build qtwenengine and its examples, I only modified  fsl-image-qt5-validation-imx.bb to add  packagegroup-qt5-webengine

This render  issue seems to be only located  to qtwebegine as the other QT examples work fine.

Anyone could help me to solve this issue?

Hello,

It take me some time  but I finally succeed to build the rootfs with wayland ( DISTRO=fsl-imx-wayland).

Unfortunately for all QT applications and whatever the QT platform used, I face the same issue regarding xcb plugin dependancy

root@imx6qsabresd:/usr/share/qt5/examples/webengine/minimal# ./minimal --platorm wayland-egl
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, wayland-egl, wayland.

Reinstalling the application may fix this problem.
Aborted

I have checked on my generated rootfs and there is no libqxcb.so  plugin that is quite normal regarding  distro I am using

root@imx6qsabresd:/usr/lib/qt5/plugins/platforms# ls
libqeglfs.so    libqminimalegl.so  libqwayland-egl.so
libqminimal.so  libqoffscreen.so   libqwayland-generic.so

So I am confused...

I assume if I use fsl-imx-xwaylanddistro it may fix the isuue but my goal is to generate the smallet rootfs providing qtwebengine that's why I initially used fsl-imx-fb distro.

Any recommandation to do so?

Thank you for your recommandation.

You are right, my Build is not based on wayland but eglfs.

I will rebuild with wayland ASAP and let you know.

Is there a known compatibility issue regarding qtwebengine and eglfs?
