QT Application launching issue

[lavakumars]

hi,

I am working on imx6qp sabre AI board. with kernel version: 4.1.15 . image freescale image built with "xwayland" setup

earlier image was built with qt (meta-qt5) version :5.5 and the application compiled with that toolchain was successfully launched .

but now I changed the meta-qt5 layer to 5.7 master branch. but the application built with its toolchain is not launching but throwing some errors like : cannot find EGLCONFIG returning null config.

                           QwaylandGlcontext : failed to create EGLcontext error:3905. etc

can someone help me to solve this?

Please also check the attachments for the error logs.

Adding some more images for extra input. used the qt examples to build and run (able to build successfully but failed to execute )

Regards,

You properly need qtwayland plugin, and a compositor like weston. Please check your package.

hi Eric Chen,

Thanx, I have wayland, Weston installed and running.

qtwayland also built all together with meta-qt5.

: But as I can see there is no eglfs platform plugins. is that a issue..?can you help on that?

Hi Lavakumar

The EGLFS should be default backend of the wayland compositor. Please check your yocto bb file for weston.

Also compare this to the 5.6.

hi Maxim Kuk,

can you help me here. i saw you worked on qt 5.7.0(here). i am facing some issues with application launching (hmi).

issues with qtwayland. actually my image built xwayland DISTRO.

Eric Chen : can you help here?.

Sorry, but I don't work with wayland.
Maybe it is wayland issue itself? Or maybe you use old yocto version?

When I updated Qt to 5.7 I also updated yocto from 1.8 to 2.1.2

hi Victor Linnik,

Thanks for the reply..

Applied the above patches but no use...

when I revert back the meta-qt5 to version 5.5 the built application works fine. gives above errors and doesn't work if I revert meta-qt5 layer to v5.7 :smileysad:.
