Bug#740451: [libqtmultimediakit1] libqtmultimediakit1 has a hard dependency on pulse audio
-----BEGIN PGP SIGNED MESSAGE-----
Hash: SHA1
Package: libqtmultimediakit1
Version: 1.2.0-3+b1
Severity: normal
After many wasted hours trying to understand how to get ppsspp's Qt
interface to use ALSA, I ironically find it does a very poor job
(whose fault that is I dont know...), but I must report here on my
related findings regardless.
The way libqtmultimediakit1 is built from qtmobility results in a hard
dependency with pulse audio, which is presumably unacceptable as pulse
should not be a requirement to use the very important Qt framework (I
run a pure ALSA system after fleeing the broken pulse as a n00b long
ago). Upstream is flagging this as a packaging issue -
https://bugreports.qt-project.org/browse/QTBUG-29742 - which feels
dubious, but thats why I'm reporting here.
In the qtmobility source, because there is no special platform config
(features/platformconfig) for our environment, when the 'configure'
script is ran it determines what features to include based on what it
can compile at the time (see line 601 onwards). I have the pulse audio
headers installed as other packages depend on them (but I don't use
pulse, and this is fine as I don't expect the presence of these
headers to break unrelated stuff).
When pulse is detected, the audio plugin 'libqtmedia_pulse.so' is
compiled, BUT ALSA SUPPORT ISNT. See 'multimedia/audio/audio.pri' at
the bottom, it literally looks for pulse audio and only if it isn't
enabled, enables ALSA!
The end result is a user with a pure ALSA system running a program
that uses libqtmultimediakit1 and getting a permanent hang when audio
is first used, as libqtmedia_pulse.so cannot cope with no running
pulse audio server (see previously-mentioned
https://bugreports.qt-project.org/browse/QTBUG-29742 - I don't see why
its acceptable to do this either...).
Please can the pulse audio dependency be clearly marked and
libqtmultimediakit1 be built in an ALSA-supported form separately?
Thanks
