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.

Betreff: [meta-freescale] qtwayland

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
