Bugzilla Bug 208407

Currently there are only ebuilds for the outdated, unmaintained Sample
Implementation for OpenAL, the last release of which being over a year old with
no new releases in sight. However, there are other, more up-to-date and better
maintained implementations available.. such as OpenAL Soft
<http://kcat.strangesoft.net/openal.html>. There is also OpenAL-ALSA
<http://dino.e4a.it/openal-alsa/>, however I can't vouch for its current
status.

Many developers are having a difficult time dealing with the latest Sample
Implementation release, its bugs and inefficiency with no improvement for it in
sight.. some having to ask their users to manually compile and install
alternative implementations, others just living with the bugs, and others
abandoning OpenAL entirely. These alternative implementations are API and ABI
compatible with any app that properly follows the OpenAL spec, and I've
personally had nothing but positive results for using OpenAL Soft, in
particular, as a drop-in replacement for the Sample Implementation.

Reproducible: Always

Steps to Reproduce:

So write them, attach and some developer will have a look (or not, depending on
time constraints and interest in such alternatives.)

"I need ebuilds" won't get you very far I'm afraid.

OpenAL Soft 1.2.218 ebuild

Okay, here's an ebuild for OpenAL Soft 1.2.218. Credit goes to Jouni Kosonen
for making it.

However, there are still some issues. The last SI release used libopenal.so.0,
while its SVN version and OpenAL Soft use libopenal.so.1. Packages that built
against the older lib will need to be rebuilt, and I don't know much about
ebuilds to print a warning for users about that.

Also that current packages that use OpenAL depend on media-libs/openal, which
is the SI and can't be installed with OpenAL Soft (they both use libopenal.so
and AL/al.h and AL/alc.h). Something like virtual/openal is needed so a user
can use the lib of their choice.

This ebuild worked for me, and the packages I rebuilt to use it worked
beautifully too.  I expect most if not all packages depending on
media-libs/openal-0.0.8 could be switched to virtual/openal-1.1 with this as
the preference.

OpenAL 0.0.8 lacks quite a bit and is now over 2 years since their last release
(2006/02/11).  There is some progress in svn but there's no prospect for a new
release anytime soon.

I volunteer to help with testing existing packages for migration to
virtual/openal-1.1

media-libs/openal-soft-1.3.253.ebuild

current version of openal-soft

I think, that is need to rename media-libs/openal to media-libs/openal-sample,
add media-libs/openal-soft, virtual/openal and possibly
app-admin/eselect-openal to select profiles (such as OpenGL)

This also works great.  Below is the diff between the two ebuilds, it's fairly
trivial.

33c33
<       !use debug || myconf="${myconf} -DCMAKE_BUILD_TYPE=Debug"

---

> 	use debug && myconf="${myconf} -DCMAKE_BUILD_TYPE=Debug"


I'll repeat that we need this.  The version of openal we have in portage right
now has numerous bugs and lacks some rather basic OpenAL 1.1 extensions such
device enumeration.

I heard rumors that OpenAL Soft will replace OpenAL SI sooner or later. So the
eselect issue could solve itself in the near future.
But the Creative comes with an own implementation, too...

Slightly changed ebuild.

Slightly changed ebuild, installs as "media-libs/openal" so no virtual thing is
required, but also is a bit cleaned up. ${PN}-${PV} in the original ebuild
should be replaced by ${P}. Patch to highlight the changes follows.

Try to reemerge games-action/cromium with openal-soft instead openal installed
;-)
Some programs need to be patched before using openal-soft

That ebuild was more to allow for quick testing, than to be the final solution
for Gentoo. ;-)
But I hope my audit of the ebuild (see the diff) was not in vain and is usefull
for the final solution, too.

This is great. The new ebuild finally makes alsa sound work for games/programs
that use openal (blender, flightgear, glest). Of course I had to recompile
them, but now I don't need to load the oss modules any more. This is a good
improvement and I hope to see this version in portage ASAP.

media-libs/openal-1.4.272.ebuild

Version 1.4.272

Any modifications besides incrementing the version number?

Also added support for custom CFLAGS (defined in /etc/make.conf) ;)

FYI: I have compiled games-sports/torcs (and media-libs/plib) against this
openal-1.4.272 successfully, however performance went down drastically (in
comparison to openal-0.8.2-r2 over aoss).

It's a little better (e.g. small pauses during rendering without enabled sound
disappeared), however still unusable. With disabled sound it has 18 FPS, with
openal-1.3.253 6 FPS and with plib over aoss about 12 FPS. FPS with
openal-0.8.2-r2 over aoss is about 15.

Just for compleness the game is linked against openal and freealut which is
linked against openal.

I don't know where the problem is exactly, but I think making virtual openal
with few alternative implemetations would be more friendly for some user
(me) :D

What if you use the OSS driver, or disable ALSA mmap? Some cards get really bad
performance issues with mmap in ALSA if the frequency isn't set to something
specific (I've personally had this occur with mplayer on my SB Live card, but
my current built-in chipset doesn't suffer from it). To use the OSS driver by
default, you can add this to ~/.alsoftrc:
[general]
drivers = oss,alsa

or to disable ALSA mmap, add:
[alsa]
mmap = off

I have disabled OSS emulation in my kernel. Trying OSS backend over aoss
crashes on SIGABORT (after message "terminate called after throwing an instance
of 'char const*'").

I have never encouter such a problem on any sound card. I have integrated AC97 
(VT82C686). However switching off mmap in ~/.alsoftrc helped in this case. Now
the performance with ALSA output is about 16--17 FPS which is really good.

Tanks o lot.

media-libs/openal-1.4.272.ebuild

Added information about solution of performance problems.

The guys from Creative now only mention OpenAl Soft for Download 
<http://connect.creativelabs.com/openal/Downloads/Forms/AllItems.aspx> on the
*NIX platform. So I suppose that the here supplied ebuilds (great work,
thanks!) should succeed the buggy OpenAl-SI in the portage tree.

I can only confirm this once more: This version here is much better that the
one currently in Portage and it would be great to see an update in this regard.

Building Chromium should work with the GIT/SVN version of OpenAL Soft, now. Are
there any other apps that fail to build or run properly? I hope to get out
OpenAL Soft 1.5 some time this week.

I have compiled and run flightgear simulator against openal soft successfully.
(I'm sorry about no version information, I have no access to the system now.)

Just tried this ebuild (1.5.304) in x86_64:
OpenAL builds fine. Games build fine and have sound (tested with Spring RTS).

This ebuild just solved problems for me emerging several packages.

This works for me, too, except scorched3d:  Scorched3d configure wants
openal-config which apparently only came with openal-0.0.8.  But warzone2100,
chromium, supertuxkart, and torcs all compiled fine.  I've only tested
Warzone2100 Supertuxkart ingame so far.

openal-1.5.304.ebuild committed, thanks for your contributions!
