Tricks of OSS installation to gentoo and funtoo

[ossuserr]

ATTENTION! It turned out that installing oss from funtoo-media overlay with production quality is not so easy! I am more than sure that it installed by default quality 3. The procedure that was given in this forum implying
ebuild oss...-.ebuild unpack
ebuild oss...-.ebuild compile
ebuild oss...-.ebuild install
ebuild oss...-.ebuild qmerge
IS WRONG AND DOES NOT WORK! If you modify configure file within .../work/oss-*/ folder and then issue ebuild ../../...../oss...-.ebuild compile GRC_QUALITY in the configure file WILL BE RESET TO 3! Moreover all instances of local_config.h will have only 3s!

The correct procedure is the following:
1. Backup alsa modules if you intend to use alsa for midi input - oss removes them and u will have to copy them back after oss installation. But this topic is covered in another place of the forum. You are sure to read it. So...
After adding funtoo-media overlay issue the command:
emerge -pv oss
to see the use flags that are proposed to you.
2. Edit /etc/portage/package.use/package.use to set the flags you want. I have such flags:
media-sound/oss gtk -salsa vmix-float -alsa -pax_kernel ogg -midi oss_cards_envy24ht oss_cards_sblive

Beware that you may have different cards in your chassis. Leave all other flags like mine.

3. Switch to gcc 4 if currently it's gcc5 by
gcc-config -l
gcc-config NUMBER
source /etc/profile

4. Go to the ebuild directory. Mine is /var/db/funtoo-media/media-sound/oss
(to have the same location you should cd to /var/db before doing git clone ...url-of-funtoo-media)
Issue two commands:
ebuild oss*.ebuild unpack
ebuild oss*.ebuild prepare

Only after prepare you should modify the configure file to avoid resetting to 3!

5. Modify configure file.

leafpad /var/tmp/portage/media-sound/oss-4.2.2011/work/oss-v4.2-build2011-src-gpl/configure

Change 3 by 6 for GRC.

6. Issue
ebuild oss*.ebuild compile

7. Now its time to check if our modifications were observed. Go to the build dir which located inside the work dir.

cd /var/tmp/portage/media-sound/oss-4.2.2011/work/build

and do:

less ./noregparm/kernel/framework/include/local_config.h
less ./prototype/usr/lib/oss/include/internals/local_config.h
less ./kernel/framework/include/local_config.h

YOU ARE TO HAVE ONLY 6 for quality!

8. Return back to the dir where ebuild is located:

cd -

and issue:

ebuild oss*.ebuild install
ebuild oss*.ebuild qmerge

This will install the driver.

9. You may switch back to gcc5 now.

10. ossdetect -v

11. soundon

12. ossdevlinks -v -r

13. Now as a user (not as a root) you may issue

ossxmix -b -n 1 &

to start ossxmix.

OSS isn't available on funtoo overlay anymore. Such a shame.. uh..
Cannot compile due to os.h problem with current git snapshot.
Patch didn't work due to pointing incorrect "os.h" out and stops me from using "configure".
According to _gpo.zugaina.org there is only one overlay supporting old (2007) OSS package - angelos.
It seems that only Arch linux has full OSS support now. -_\

If Gentoo is so difficult for you, you may try Linux Mint.
