Gentoo OSS4 overlay

[cesium]

Hi,

There's a gentoo oss4 overlay at: http://hg.atheme.org/users/majeru/portage-overlay/ . oss-devel-9999 is the latest oss from mercurial, and it also has useful ebuilds for skype-oss and gst-plugins-oss4.

Hi,

There's a gentoo oss4 overlay at: http://hg.atheme.org/users/majeru/portage-overlay/ . oss-devel-9999 is the latest oss from mercurial, and it also has useful ebuilds for skype-oss and gst-plugins-oss4.

Does it have "Production quality" enabled?

[cesium]

Nope. But since an ebuild is not a binary package, it can be edited to achieve this...

Have anybody managed to recompile OSS4 for Gentoo, to enable "Production quality"?

Have anybody managed to recompile OSS4 for Gentoo, to enable "Production quality"?

What do you mean by "Production quality"? Is there any configure option you would like to enable?

I mean exactly that.

How to enable "production quality with extra precision"?

It can be easily enabled on Ubuntu and Arch.
Many thanks to Cesium once more.

"Production quality" compilation for gentoo can be achieved by next steps:
# layman -a oss-overlay (see layman help for proper configs to /etc/make.conf and other related things).
Usually layman files stored at /var/lib/layman/oss-overlay
# cd /var/lib/layman/oss-overlay/media-sound/oss-devel
/var/lib/layman/oss-overlay/media-sound/oss-devel #
/files
Manifest
oss-devel-4.2_rc1.ebuild
oss-devel-9999.ebuild
I started to play with 9999 ebuild.So next do ebuild oss-devel-9999* unpack
emerge will look at mercurial.opensound.com for any updates and then unpack sources code to /var/tmp/portage/media-sound/oss-devel-9999/work
Next is to do ebuild configure, find /kernel/firmware/include/local_config.h
nd edit CONFIG_OSS_GRC_MAX_QUALITY to 7, save changes and finally do ebuild merge. For some reason mercurial.opensound.com not available few days, I'm getting error that update failed,possibly, due to site is down, is everything ok?

I've updated the repository address in the oss-devel-9999. Hannu moved it to sourceforge.net.

The layman oss-devel ebuild fetched today containes no src_configure().
Configuring is done in src compile. So you can't edit $BUILDDIR/kernel/framework/include/local_config because it is simple not there yet.

When you run ebuild compile and ctrl-c it, you can edit it, but not continue because it calls configure again and bails out because the build dir is not empty.

I tried moving the relevant line to src_configure but the code there never ran. even the echo line didn't..

[feli33]

WELL just edit /var/tmp/portage/media-sound/oss-devel-9999/work/opensound/configure to
min 3 max 6
after you do ebuild unpack
no need to change localconfig ever during the merge
then you can ebuild merge.

this is actually tested and it works folks..
setting 7 never gives you EXTRA PRECISION mode 6. Even if localconfig is altered.
It is disabled in the source because it causes crash.

Hey, OSS is refusing to load on my system. I'm running Sabayon, which is a variant of Gentoo. I added oss-overlay to portage, have the oss-devel-9999 ebuild installed, it built fine. When I ran soundon, I got the "failed to disable conflicting sound drivers" error... I've recompiled my kernel without static support for ALSA/legacy OSS, and /var/log/soundon.log says this:

Failed to disable conflicting sound drivers

I can't see any modules that're related to sound/OSS.

What do I do? Do I have to make the /dev/mixer, /dev/dsp etc. nodes? Running `modprobe snd_sbxfi` seems to work without error, by the way, there's just nothing created in /dev when I do that...

Is this a problem occuring because I'm using Sabayon, which is a precompiled desktop setup?

EDIT: I see it might be a problem with devfs? Something removed /dev/dspN and /dev/mixer? ALSA was working fine with my soundcards, I just wanted to replace it with OSS4... I tried recreating /dev/dsp and /dev/mixer (and dsp0/mixer0 respectively) using mknod, but it apparently has no effect...

[cesium]

You could try to run "modprobe osscore", "modprobe oss_sbxfi", "ossdetect -d", "ossdevlinks" to load it manually (all of these under root). And can you post output of 'lspci -vnn' and of 'cat /proc/devices'?

some help needed thx

[cesium]

Odd. Does /lib/modules/$(uname -r) directory even exist? Maybe emerging module-rebuild might help?

[babau]

yes directory does exist

modules-rebuild did not help
