re-emerging kdemultimedia [libpng,alsa]

I need to re-emerge kdemultimedia because of new versions of libpng (1.2.1-r1) and alsa (0.9.0_rc1-r2) but emerge kdemultimedia gives me the following error after a while:

i have the same problem. I set -alsa, so i dont get alsa-support. But KonCD is not set to be compiled. Do you know why?

I just finished my first Gentoo install. Most fun I've ever had on a computer! But emerge kde bombed on kdemultimedia in the TIMIDITY directory. So I installed xfce, the Gentoo Linux of desktop managers. Sox (which does sound for Xfce) failed on alsa.c.

But actually both KDE and Xfce run fine -- just no sound. I think something is wrong with alsa.c.

I followed the directions for a new install of alsa0.9: set SOUND_CONFIG=y and other SOUND_CONFIG_xxx commented out and "is not set" in /usr/src/linux/.config. Then I recompiled and installed the new kernel. emerge alsa worked.

But emerge sox and emerge kdemultimedia fail in the same places as before.

I'm getting the same problem myself. I can't find any discussions on this anywhere else.

I updated ALSA today, so I don't know if this has to do with the newer version or not. I still have sound, but that's because kdemultimedia compiled when I first set up my system.

I got the same error, but with version kdemultimedia-3.0-r1 ebuild.

I was just reading the gentoo-dev list, and a workaround has been posted there for this issue. You need to edit your USE flags in make.conf to -alsa. This means it will compile without alsa support (duh!), but it seems it is the only way round it at the moment.

When this happens (kdemultimedia failing), you do have a working kde install, just alot of things are missing, so you can still use kde, just with limited functionality.
I would like to have alsa sound in my programs, so I am trying to use an alsa .5 build and then remerge kdemultimedia3, to see if anything comes out of it, cause that is what is on my desktop.
It kind of stinks that this isn't working right now. :cry:

edit: nope, that didn't work.

Dan asked that I post this in his name after I emailed him on our favorite subject:

Hello everyone,

Unfortunately, there's no currently known way to compile our kdemultimedia
against alsa 0.9. My "excuse" is that there's an open bug on bugs.kde.org
about it too (http://bugs.kde.org/db/39/39574.html). I've been trying to
awake interest about it, but there've been no responses from the kde side so
far. I'm continuing in my attempts, and eventually it'll be resolved but I'm
afraid it may take some time.

Compilnig kdemm against alsa <0.9 should work (worked so far). Compiling kdemm
without alsa support means that kmix and kmidi/timidity wont' have alsa
support. I'm not sure what the actual ramifications of the latter are since I
don't use alsa myself. noatun and the other kdemm programs should go on
working perfectly since they merely use arts which does compile with alsa 0.9
support.

koncd: it is included in the kdemm-3.0 tarball but is not included in the
default compile because it's not considered stable enough. (There are several
such packages in most kde packages.) I'm currently working on 'subpackages'
or 'children packages' for kde-base/*, which means that instead of compiling
all of kdemultimedia there'll be separate ebuilds for noatun, kmix, kmidi
etc. and then we can have ebuilds for things that aren't build by default
like koncd as well. The master ("parent") kde-base/kdemultimedia ebuild will
remain (it'll depend on all its children, except those not built by default)
so the transition should be nearly transparent.

From what Dan says, we should be able to complete the install of KDE if we install an old version of alsa (<0.9) without using USE="-alsa". I think I've figured out "emerge unmerge alsa", but how do I find an older version of alsa and emerge it? The only references in my /usr/portage are to alsa 0.5.

Well I used the "old" alsa drivers (version 0.5.12a) and everything is working fine !!

So I would suggest to you guys to use the older drivers, not the new ones (I think the 0.9 alsa drivers are not yet fully supported by kde)

I tried to compile kde with the new alsa drivers, not so long ago, on my slackware box ... that didn't work out ... so to be safe, I used the older alsa drivers for my gentoo install. That seemed to have been a good choice after all :

just an opinion

I am using alsa-0.9.0_cvs20020320-12 with kdemultimedia3-3.0-9 on my SuSE 8.0 system. They work together, but SuSE has not posted the src.rpms on ftp.suse.com yet. (They are on my DVD, however.)

I tried emerge umerge alsa, deleted the alsa0.9 ebuilds and emerged alsa again, using the alsa0.5 ebuild. alsa installs but emerge kdemultimedia still fails in the same place.

I've also been having this problem. I found that simply changing the USE setting to -alsa after kdemultimedia failed and then continuing the emerge did not work. I had to manually emerge unmerge all of the multimedia-related stuff that emerge kde had already installed and try again.

I also tried going back to alsa version 0.5, but this didn't work. This was however before I thought of unmerging what had installed so far, so perhaps if I had done that and then tried, I would have been ok.

(The errors I was getting after installing alsa 0.5 when building kdemultimedia were about libasound.so.2 not being available.)

For what it's worth:

A few days ago I upgraded my kernel to 2.4.19-r10 and set up ALSA as a kernel module. Then I followed the Gentoo ALSA guide, and finally re-emerged all of KDE with the alsa USE flag. I can confirm that kdemultimedia compiled with no problems.
