I have been able to build angstrom-lxde-image and console-trdx-image. Our application requires windows manager support. QT advised me to integrate Wayland in the build. I am new to Yocto project. Can anybody here give me instructions of how to add or modify recipes to build Wayland?
Thank you.
William
Wayland is not currently supported by our Linux images. You may be able to build the Boot2Qt image with wayland support enabled. It is commonly added to an image through DISTRO_FEATURES, but may also require additional adding, removing & modification of recipes/packages. I’m also not sure if this would be fully supported in conjunction with the closed source vivante graphics drivers.
If you simply need a window manager with Qt, I recommend building the angstrom-qt5-x11-image recipe in meta-toradex:
bitbake angstrom-qt5-x11-image
angstrom-qt5-x11-image provides our standard Angstrom-based X11 Linux image along with the non-commercial Qt5 components.
As Brandon already wrote we at Toradex have no image recipe based on weston.
There is a core-image-weston recipe which could be used to try out weston. We at Toradex did only play with it briefly.
Assuming you have a V2.6 openembedded setup as explained here you could:
To do so add In conf/local.conf::
DISTRO_FEATURES_remove = " x11 "
IMAGE_INSTALL_append = " qtbase qtbase-fonts qtbase-plugins qtwayland cinematicexperience"
IMAGE_INSTALL_append = " ${CORE_IMAGE_BASE_INSTALL}"
e.g.
MACHINE=colibri-imx6 bitbake core-image-weston
e.g.:
sudo tar xf Colibri_iMX6_LinuxImageV2.6Beta2_20160630.tar.bz2
cd Colibri_iMX6_LinuxImageV2.6/rootfs
sudo rm *
sudo tar xf <path-to-buildoutput>/Angstrom-core-image-weston-glibc-ipk-v2015.12-colibri-imx6.rootfs.tar.bz2
cd ../colibri-imx6_bin
ls -l

sudo ln -sf uImage--3.14.52-r0-imx6dl-colibri-eval-v3-*.dtb uImage-imx6dl-colibri-eval-v3.dtb
ls -l
e.g. I added two lines in rootfs/init.d/weston:

After boot I had to restart the automatically started weston

Hi Max
Thank you for your step-by-step instructions.
However my bitbake ran into errors:

I was able to go through the end of the procedure after I modified the qtbase_git.bb file as suggested. But the “Qt5_CinematicExperience” application was not able to run. Here is the log:

Are you using a Colibri iMX6S?
If you use a Colibri iMX6DL are you hit by this bug?

I am using Colibri iMX6s with 256MB RAM.

I ran my application built with Toradex BSP V2.6 and got this error:
root@colibri-imx6:/usr/bin# ./PSA_ENTRY_BOOTH55 &
root@colibri-imx6:/usr/bin# This application failed to start because it could not find or load the Qt platform plugin “xcb”.
Available platform plugins are: eglfs, minimal, minimalegl, offscreen, wayland-egl, wayland.
Reinstalling the application may fix this problem.

Looks like I am missing libxcb.so.1 library, right? This library is available in the /usr/lib directory in V2.6 angstrom-qt5-x11 image. But with the procedure posted above, it is replaced with libraries generated in core-image-weston, which does not seem to have the libxcb.
If you start your application without specifying a platform Qt will default to X11.
But you specifically did not want X11 in your image so libxcb is not part of the image. (Plus the image does not have all the rest nedded to run the X server)
Did you actually start weston before you started your application?
/etc/init.d/weston restart
./PSA_ENTRY_BOOTH55 --platform wayland
Yes, I did start weston prior to my application:
