    xdg_surface________ stuff is not part of libwayland-client and I

    exported by libwayland-client, and if the example code doesn't use
    either of those it has to quit.


These protocols are not a part of libwayland, but Weston. You can find
their specification in weston/protocol directory (those xml files) and
you can generate sources from them using wayland-scanner. Then you can
link against these sources (namely xdg-shell-protocol.c for xdg_* stuff
and fullscreen-shell-procotol.c for the another).


But as far as I know,
the common wl_surface should be enough for creating a window without
borders and buttons in Weston (that's how the
weston/tests/weston-test-client-helpers.c works).

That's not exactly true. In order for a surface to be displayed on the screen, it needs to have a role. The role of the surface defines what happens when a buffer is attached to it. In the case of the file you mentioned, the role of the surface is set using the wl_test interface. This is not quite clear since it is done by the wl_test::move_surface request.

So if you want to use
only libwayland-client, as you wrote before, you should not use
xdg_shell and fullscreen_shell. What you need to do is:

An alternative would be to use wl_shell. While in the long run it is expected that xdg_shell will replace it, it is currently shipped with libwayland-client and should work.

You can look at the link below for the commit that changed simple-shm to use xdg_shell instead of wl_shell.
