[Pkg-libvirt-maintainers] Bug#905700: libvirt: Please drop build-depends on dwarves - "WARNING: pdwtags appears broken; skipping the ../../../src/lxc_protocol-struct test"

[Niels Thykier]

Source: libvirt
Severity: important

Hi,

Please consider dropping the build dependency on dwarves as dwarves
does not support DWARF4 and is therefore completely useless.  At the
moment, all libvirt tests relying on dwarves appears to be skipped
(see below), so the build-dependency is dead weight and prevents us
from removing dwarves from the archive (libvirt is the only package
with a relation on dwarves and only need it for tests).

The obvious alternative is fixing dwarves, but:

 * Upstream has not made a release since 2012.
 * Upstream's blog has no mention of working on dwarves to support
   DWARF 4
 * The Debian bug (#779809) has not had a maintainer reply at all
   despite being open since 2015.

Therefore, I think removing the dwarves relation from libvirt is the
most reasonable forward if you do not have the time / energy to become
upstream for dwarves.

Thanks,
~Niels
