Debugging weston-launch

[Edgar Mobile]

I have to debug an Aarch64 based Linux system where weston-launch gets stuck in 
the main loop poll:

GitLab
A lightweight and functional Wayland compositor. Switch branch/tag. weston 
libweston; weston-launch.c
gitlab.freedesktop.org
Can someone tell me how to start debugging this?

Greetings,

I work my way through this Wayland tutorial:

https://wiki.tizen.org/Wayland_xdg-shell_protocol

To compile the example, I need a certain header allegedly in the Weston source 
tree:

xdg-shell-client-protocol.h

But I can't find it. What should I do to make it appear?

Regards
