Hi Gnome folks and Niels,

Ibus is the input method GNOME uses as default and I am adding the
wayland support.

I need help on the ibus bug #750902 but can not locate good examples to

I am not seeking this path.

I want to do this but I am not quite sure what exactly to do.

What I need is an working example of existing package.  Can you point me
any good example?

My specific questions are how to update debian/control and debian/rules?

You say "linux-only" binary but what exactly should I use in the
debian/control?  linux-any seems to be the word used in the policy
( https://www.debian.org/doc/debian-policy/ch-customized-programs.html#s-arch-wildcard-spec )

Is this correct for debian/control?
| Source: ibus
| ...
| Build-Depends: autoconf,
| ...
|                libwayland-dev [linux-any],
| ...
| Package: ibus-wayland
| Architecture: linux-any
| ...

Also, what is the most effective way to make debian/rules architecture
dependent?  I do not know how to set $(OS) elegantly.

| ifdef ($(OS),linux-any)
| override_dh_auto_configure:
|         dh_auto_configure -- \
|                 --enable-wayland \
|                 --enable-introspection \
| ...
| else
| override_dh_auto_configure:
|         dh_auto_configure -- \
|                 --enable-introspection \
| ...
| endif

Your help to point me to the good example is most appreciated.
