Hi all.
Recently I've been having fun with the latest pulseaudio quirk: it
doesn't build because of the --as-needed flag in linking. I don't
understand linking in depth, but as I understood it there's some
dependency cycle that gets triggered by the aforementioned ld flag.
However this doesn't happen when building in a chroot, where the
package builds fine.
It isn't the only package where it happens, and I have a handful of
questions about the correct way to handle this.
1. If something like this happens, is it an upstream bug?
2. If it builds fine in a chroot there's obviously a software that
triggers the bug, does it mean I am missing a dependency?
3. If a package builds inside a chroot but not outside, should it be
changed in such a way that it builds everywhere regardless of the
changes that are to be made? Or should it be left as it is, and
related bugs closed with "build it in a chroot"?
4. What does the absence of the ld flag imply in practical terms? Is
it just a "nice to have" or has it some real implications?
It is probably an addition dep (optional) that is being detected on your
system and causing the failure. Personally, I would build in a chroot and
ignore the issue. There are plenty of packages that should only be built in
a chroot due to issues similar to this and _ALL_ packages should be built in
one anyway.

Shouldn't a PKGBUILD try to cover all potential normal Arch setups, though?
If it is known that a package conflicts with the build, and it can't be
traced to the
individual package so it can be added in conflicts() (or we may not want it
there),
then I think the PKGBUILD should be modified to work in all common
scenarios.
I looks like pulse-audio will link to itself and that causes issues with
--as-needed. Heimdal had (has?) the same issue so had something like
this in the PKGBUILD:
[ -e /usr/lib/libasn1.so ] && echo "## remove old heimdal pkg first ##"
&& return 1
If pulse-audio only fails to build when pulse-audio is present, a line
like that in the PKGBUILD will solve all problems. Or just a comment at
the top like the current heimdal package:
#
### Attention: remove old pkg before building - it links against itself! ###
