In order to install Kdelibs-4.2.1, I was forced to install Phonon, which in turn requires Gstreamer (or equivalent). I do not have speakers attached to my machine & do not have sound enabled in my kernel. Some users (not me) may be deaf & are nonetheless forced to install pkgs they have no conceivable use for. Why does Kdelibs 4 require installation of sound software ?
Ok all packages should have optional phonon support for kde it would need testing but i propose to make phonon optionaly depend on kdelibs with +alsa by default (phonon needs alsa) and then add eclass check that add +-alsa check on kdelibs and append KDE4_DISABLE_MULTIMEDIA ON/OFF based on the need. Or we might walk throught tree and check each app if it could run with phonon. Other suggestions?
Thanks for the very prompt & constructive response. I look forward to seeing which course the KDE devs choose to adopt.
He he :] I am kde dev, and i would probably end up doing it, i am just asking others if they have better solution :D

Your proposal sounds good, but are you sure phonon is *really* optional?
Indeed it is. But the problem might be that pple will find out that this way they can install qt-phonon :( So it might be good to actualy block qt-phonon on kdelibs directly.

Can it be fixed by a Gentoo patch ? Should a bug be registered with KDE themselves ? As always, I appreciate the work done by Gentoo devs, but I object very strongly to being forced to install sound software simple to be able to use some KDE apps.

I have submitted bug 190601 to KDE asking them to ensure that sound is not required in order to compile Kdelibs-4.x.x or other KDE packages.
Well, there was a quick response from KDE : "There is no bug here. Phonon is just an API for sound, not an actual sound software. If your distro forces the installation of an actual sound software when installing Phonon, then it is a matter for them". So what can Gentoo's KDE devs do to stop this imposition ?
I am trying to put together a compact virtual machine with qt4 and kde4 and I also would like to install kde4 without gstreamer/xine/(other equivalent). Is there a workaround available?
Has this been fixed ? I checked today & 'emerge -pv phonon-4.4_pre20090520' doesn't require any other sound package, but IIRC previously the problem arose only when the actual configure-compile steps got underway. I have no intention of using the KDE 4 desktop (Fluxbox is my preference), but I want to use a few KDE apps like Konsole & Konqueror & plan to try out 4.3.1 once it reaches 'testing' around October. It would be nice to have this problem resolved before then.
Phonon is now audio/video framework for KDE SC. We simply can't strip it out. But by messing with phonon useflags you can make it not depend on any sound packages. It wont get better. Cheers
There's no way to "mess with use flags", as you put it, but I succeeded in emerging Phonon via 'USE="gstreamer" emerge --nodeps phonon': it compiles & installs & all the usual KDE apps started after a reboot (I don't use the KDE desktop, prefering Fluxbox). I previously unmerged Gst-plugins-meta & all its dependencies (AFAIK). So I have 1 remaining question for the Gentoo dev(s): if Phonon can be emerged successfully without Gstreamer or any of its dependencies, why does Portage still give me an error message, if I try to emerge Phonon without 'USE="gstreamer"' (or "xine" or "pulseaudio") ? Shouldn't that message be deleted from the ebuild or wherever it is located ?
Reopening, phonon-vlc is in tree now, as well deps can be relaxed a bit.

Recently, upstream phonon split their basic phonon from its backends [1] I just pushed a commit in overlay that reflects this for our live ebuilds, it is still a wip though (especially to better identify the deps and to add all backends, since xine and gstreamer split is still a wip in upstream build system as well). Upstream said that next phonon release will be in split tarballs. I'm resolving the bug, the change will hit the tree in next phonon version.
