weston with wayland-backend.so is throwing error in arm-64

I am trying to run a qtwayland application via Wayland. I've set the XDG_RUNTIME_DIR variable as shown below: export XDG_RUNTIME_DIR=/tmp/${UID}-runtime-dir mkdir "${XDG_RUNTIME_DIR}" chmod 0700 "${XDG_RUNTIME_DIR}" After setting the weston.ini file in **~/.config **folder i tried to run the below command: weston --tty=0 --backend=wayland-backend.so the output I got is shown below:

Also when I run ls $XDG_RUNTIME_DIR I don't find any socket (due to the failure of compositor I guess) what should I do? Any help will be appreciated.
