I found your samples through https://unix.stackexchange.com/a/512261/335461
I'm able to compile the code, but when trying to execute, I get a segmentation fault.
Here is the gdb backtrace:

I'm trying to launch it from a terminal app (alacritty) under the sway window manager. Wayland version is 1.19

I noticed that you haven't put your code in this repo under an open source license. If you want others to be able to use and build on what you've written, please consider adding a license so there is no fear of future difficulties. The MIT license would be preferable to me as it is the standard for many Wayland related projects. Thanks.

Blocking in wl_display_dispatch, which should be replaced by wl_display_dispatch_pending as long as surface is not configured.
This is what weston/clients/simple-egl.c is doing.
Also what I am doing here in the D bindings: https://github.com/rtbo/wayland-d/blob/master/examples/egl_window/source/egl_window.d

See http://manpages.ubuntu.com/manpages/xenial/man3/drmModeGetResources.3.html - function may return NULL, at which point a segfault will happen a few lines later.

Enough said.

On Fedora 25, compiling any of the examples and running them gives this error:

wl_registry@2: error 0: invalid version for global wl_compositor (2): 0 is not a valid version

Changing the last argument in wl_registry_bind everywhere from 0 to 1 seems to work.

(But since I basically started learning Wayland today, I am not sure if this is the right fix and hence an issue instead of pull request)
