Dear Benjamin,
thanks for the reply.


with "fsl-image-qt5" I do not have 'eglfs' platform plugin. I looked into qt-base recipe and the 'eglfs' exists there!!
when i build image "fsl-image-gui" then I was able to run $qml-copositor -platform eglfs
but I want qt libraries! how could I have eglfs on "fsl-image-qt5" it just has: offscreen, minimal, wayland, wayland-egl.
sorry if the question is idiotic! i'm new in qt and yocto!


thanks again for your help.
Vahid
Ok, it looks like the fsl-image-qt5 is set up for X11 and the fsl-image-gui image does not contain any Qt libs. To be honest I haven't used the yocto bsp 4.1.0-2.1.0 from NXP, so I do not know more details about its recipe contents and it could be that there is no QtWayland ready-to use image for you.
Maybe you should create your own image recipe to get QtWayland running.

Dear all,
I have imx6sxsabresd, yocto 4.1.0-2.1.0 from NXP.
i built image fsl-image-qt5
also qtwayland
weston works fine.
qml-compositor example does not work:
on running weston : 
unable to lock lockfile /run/user/root/wayland-0.lock, maybe another compositor is running.
 
without weston:
QXcbConnection: Could not connect to display : 0.0 
It looks like the qml-compositor is started with the xcb QPA plugin. Have you installed a X server and it is running?
On my i.MX6 I use the Qt compositor examples with the eglfs QPA plugin (-platform eglfs), but of course it depends on your image setup. 
I also have to set the XDG_RUNTIME_DIR env var.
E.g.:
export XDG_RUNTIME_DIR=/tmp/weston-$USER
mkdir -p /tmp/weston-$USER
chmod 700 /tmp/weston-$USER
qml-compositor -platform eglfs






 
 
PS:
LD_LIBRARY_PATH=/usr/lib
DISPLAY=:0.0 
 
for qtwayland i copied :
<board dir>/tmp/work/cortexA9hf-neon-mx6sx-poky-linux-gnueabi/qtwayland/image/usr to <board>/usr/
 
could anyone help me please?
1- should i bitbake another image?
2- should i compile compositor and install it on board?
3- do i need specific environment variable? 
4- does qtwayland works for this distribution i have?
 
thanks a lot
