--- Comment #1 from Guido Falsi <madpilot at FreeBSD.org> ---
Hi,

The xfce4-print port (together with others, like xfce4-mixer) has been dropped
and is not being developed anymore. It is in the ports tree, but bit rot is
quickly getting in.

In this case you are compiling with the CUPS option (off by default), and it
appears that recent changes in the cups include files caused cups support in
xfce4-print to break.

The upstream commit in cups causing this can be viewed at [1]

xfce4-print was accessing cups private structures. We already had a patch in
out tree adding a define which allowed the include file to expose these
deprecated structures. Such flag has been removed by the upstream, causing the
breakage you see.

I'm sorry, but short of a rewrite of all the relevant code in xfce4-print this
cannot be fixed, but with no upstream this is improbable.

Also note that xfce4-print, also depends on GTK2. XFCE development versions
have already removed all support for GTK2, so any xfce component depending on
GTK2 needs to be ported to GTK3 or will fail to compile with the future release
of XFCE 4.16.

Obviously for components whose support has been dropped long ago by upstream
such porting to GTK3 is very improbable.

xfce4-print, xfce4-mixer, xfce4-quicklauncher-plugin are some popular XFCE
ports that WILL be removed from the tree when XFCE will be updated to 4.16,m
and risk breaking irreparably before that due to bit rot (no upstream
development).

Some other xfce parts have not been ported to GTK3 up to now, but are actively
supported, and I expect them to be ported by the time 4.16 beta versions will
be around.

I'm sorry but unless someone with cups development knowledge comes up with
patches, I can only remove the CUPS option from the port since it's broken.
I'll also take this as a chance to mark all the xfce ports which are not being
supported upstream and still depending on gtk2 as DEPRECATED in our tree to let
it known that they could be removed at any time if any non trivial breakage
happens.

Leaving the bug in open state for now, at least until I commit the change
described above.
