Bugzilla Bug 118178

Today I compiled kdelibs using avahi-0.6.2 with the mdnsresponder-compat
use-flag set instead of the mDNSResponder ebuild.
It compiled and linked without problems.
If upstream doesn't include direct support for avahi in future versions, it
would be nice to have the dependency on mDSNResponder in kdelibs changed in the
way avahi could be used.
What do you think?

That it does not work, already tried.

You're right. It doesn't work out of the box.
The kdnssd-avahi package from http://helios.et.put.poznan.pl/~jstachow/pub/ is
needed. Compilation was a bit of a problem (usual qt/3 problems), but it works
or at least "zeroconf:/" in konqueror works.

I hope I do not get on your nerves, but I tried it and also made an ebuild for
kdnssd-avahi and it seems to work perfectly.
What was the problem, when you tried it?

kdnssd-avahi-0.1.2.ebuild

This is the ebuild for kdnssd-avahi, which replaces mDNSResponder with avahi
support in kde.

Okay it might work with the other package then :)
For sure, it wasn't working out of the box.
But I'd rather wait to see what upstream says, kdnssd-avahi is in playground,
that means "no support from upstream".

Ebuild for kdnssd-avahi

'need-kde 3.5' needs to be inside the function src_compile() otherwise emerge
looks for kde v0.1.2 and not kde v3.5

(From update of attachment 81356 [details])
My patch doesn't work either. There is an issue with the need-kde command.
Outside the src_compile function (as in the original ebuild) I get the error:
emerge: there are no ebuilds to satisfy "~kde-base/kdelibs-0.1.2".
(dependency required by "kde-base/kdnssd-avahi-0.1.2" [ebuild])

With it inside the src_compile function (as with my patch) I get the error:
+ make install DESTDIR=/var/tmp/portage/kdnssd-avahi-0.1.2/image/
destdir=/var/tmp/portage/kdnssd-avahi-0.1.2/image/
make: *** No rule to make target 'install'. Stop.
...
!!! died running make install, kde_src_install:make
!!! if you need support, post the topmost build error, and the call stack if
relevant.

If i remove 'need-kde 3.5' all together then the libraries get installed to
/usr/lib instead of the required /usr/kde/3.5/lib/

(a manual copy seems to fix everything)

kdnssd-avahi-0.1.2.ebuild

Fixed the ebuild, hopefully someone that knows the kde eclass better than me
can make this prettier, but it works now.

kdelibs-3.5.2-r4.ebuild_kdnssd-avahi.diff

Here's a patch to the kdelibs-3.5.2-r4 ebuild that has the proper dependencies
for kdnssd-avahi.

Forgot to handle the arts and kdeenablefinal USE flags.

Should the last part of that  patch read:

if (use zeroconf || use avahi); then
     myconf="${myconf} --enable-dnssd"
else
     myconf="${myconf} --disable-dnssd"
fi

No, because that would use the zeroconf support built into kdelibs instead of
the avahi support the new kdnssd-avahi package provides.

kdelibs-3.5.2-r6_kdnssd-avahi.patch

Patch against the kdelibs-3.5.2-r6 ebuild to support kdnssd-avahi

Is there any chance to get Avahi support integrated into the 3.5.4 ebuils?  As
the KDE team is concentrating on KDE4 now, chances that kdnssd-avahi will be
included in kdelibs3 or whatever are IMO pretty low.

Updated DEPENDs to allow avahi would be cool, I'd test the avahi-enabled
ebuilds :)

I'm not sure, but I think this <http://bugs.kde.org/show_bug.cgi?id=134212>
patch will be needed.

I've found that USE=mdnsresponder-compat makes little difference to KDE's use
of Avahi, it seems to ignore it regardless.

That said, with the kdnssd-avahi package, all is happy.  Is it worth poking
upstream again on this?  I run a dual-stack IPv4/IPv6 network, and as long as
mDNSResponder lacks IPv6 support, I cannot use it on my network.

I'll be taking care of this as soon as I have time, but right now is likely to
be next week..

Will take care of it now, although the kdnssd-avahi ebuild I rewrote for the
most part.

Thanks Nathan, all in portage now :)

So that's the correct way to do that. Much simpler :)
Good to see this is in portage now!
