Hello,

As far as zsnes is concerned, I will upload a package removing
zsnes:amd64. Whether zsnes:i386 will be installable or not will then
only depend on #638741.

If zsnes really is i386-only, then that seems like the best answer to me.
It's not really blocked on libao being converted - at least not in the
sense that it will need further changes after it is, or can't change until
it is.

I only took over libao a few weeks ago, and I'm not really any more keen
to relocate all its files on the eve of the freeze than I was to do that
just a couple of weeks before it. I don't know if anybody else has done
a proper audit of this to be sure there will be no problems with its
plugins - a cursory glance seems to indicate they'll probably be ok, but
I'm far from being certain enough about that to do a "beat the freeze"
upload making this change.

This one had gone on my "worry about m-a for wheezy+1" list - when m-a
itself is hopefully a little more settled and some of its intrinsic
problems might actually have solutions. I might push one to experimental
in the meantime if there is real call for it - but I think it's way too
late to be experimenting with this in wheezy release candidates now.

Cheers,
Ron

It has been applied in libao (1.1.0-1ubuntu2) dated back to Mon, 19

as has long been anounced ia32-libs-dev will not be in wheezy since
32bit support will be replaced by multiarch. Since your package still
Build-Depends on ia32-libs-dev this means it will no longer build from
source. Please multiarchify your package.

That's easier said than done. This week I tried to install zsnes:i386
on amd64 and it failed, because one of its dependencies was not yet
multiarchyfied. I am looking at you, libao!

As mentioned in the bug log for 638741 the zsnes package doesn't have to
wait for libao4. It should only set M-A: foreign and drop the amd64
build. It will then be installable with libao4:i386 if libao4:amd64
isn't installed. Not ideal but ...


As for libao4 and the multiarch patch in the BTS. I took a quick look at
the patch and I consider that incomplete. As is it switches the plugin
dir to the multiarch dir without providing backward compatibility. That
means the patch breaks all plugins for libao4 and they all need to be
multiarchified together with versioned Breaks and Depends. This is
usualy not ideal. Better would be to have libao4 look in both the old
plugin dir as well as the new plugin dir. That way plugins can be
multiarchified over time.

Other than that the patch looks fine.

MfG
Goswin

PS: When you do decide to multiarchify libao4 please file bugs against all
the plugin packages if not already present and user tag them with
user = , usertag = multiarch.

And has had completely unresponded-to bugs there, like:

"libao looks for the wrong plugin directory, when one is using the
32-bit .so provided on a 64 bit system."
