I had a strange problem: after weston had started on RPi, I couldn't get any of the clients to run. I'm posting this in the hope that it will help someone else solve similar problems.
Steps taken: 1. went with raspbian (from official image) 2. rebuilt cairo packages to enable cairo-glesv2 3. followed http://wayland.freedesktop.org/raspberrypi.html with slight modifications: A) --disable-configuration for wayland build B) made sure weston was built without cairo-egl C) -rwsr-xr-x 1 root pi 382624 Jan 3 10:55 local/bin/weston Last change was needed to get weston running at all. It starts, and seems to work, but trying to launch any of the applications simply results in an error. Weston-terminal, smoke and flower all result in identical error message: """ failed to create display: Permission denied failed to create display: Permission denied """ ... which was kind of strange. Looking through the client code, this comes from display_create() error handling, and the code itself eventually expands to wl_display_connect(). The reason seems to be this: srwxr-xr-x 1 root pi 0 Jan 3 11:52 wayland-0 Yep. Non-root user doesn't have permission to connect to Wayland socket. ** ONE-TIME SOLUTION ** After weston has launched: % sudo chmod g+w /run/shm/wayland/wayland-0 ** "More permanent" solution ** Launch weston via a wrapper which first sets umask to 0002, so the socket is created with group rw bits set. That's it. Have fun, and keep on hacking. -- Mika Boström / mika.bost...@nomovok.com Software Architect _______________________________________________ wayland-devel mailing list wayland-devel@lists.freedesktop.org http://lists.freedesktop.org/mailman/listinfo/wayland-devel
