UT2004 openAL alsa-dev

[DarkManX4lf]

i read in this guide:

http://www.linux-gamers.net/modules/...p?articleid=40

in section three if i use the openAL module suggested there, that i would get a performance boost when playing UT2004 and using openAL, and an Audigy card. I then downloaded it, extracted, in terminal i wento the src dir, and typed make, to make the module (not sure if its a module) but i get this error

i went to the linux-gamers forum, and it was stated there (from another person posting the similar problem) that i need alsa-dev package from my distro...but in synpatic i cant find it, and i cant apt-get install alsa-dev....

so basically i want to know how do i get this to work ?

[DarkManX4lf]

anyone know how to get this compiled properly?

[evilghost]

Before you go down this path, perhaps try running UT2004 with sound off, to see if recompiling ALSA would do anything for you? Seems like a lot of work that may have zero yield for you...

gedit ~/.ut2004/System/UT2004.ini
(Find line "UseSound=True" and change to UseSound="False" under [Engine.GameEngine])

Try running UT2004 then, with a "stat fps" and see if there's even a change. On my system, there was none. You could also rename/move the openal.so in the [UT2004 Installation Folder]/System directory if you don't trust UseSound=False.

yep, i had to rename openal.so, it the sound would still be there if i set "usesound=false" also i did get a fps boost, almost +20fps

[evilghost]

Woah....I just did the UseSound=False, and it had no affect. I renamed openal.so and saw about a 15 to 20 fps boost. Excellent. Now we just need to figure out how to recompile openal.so for our system. I've got a Sound Blaster Live so we should be able to use the same openal.so module.

Today I'm going to try to get this figured out and will gladly share anything I've learned.

Here you go:

sudo apt-get install alsa-source
sudo apt-get install alsa-headers
cd ~/openal-alsa-emu10k1-1.2/src
make

Now I get:

Have to run, hopefully this will be enough to get us started down the path to a solution. I hope to check back later in the afternoon, hopefully you've found a solution

[DarkManX4lf]

nah i havent found any solution, but i do know that UT2004 comes with its own openal and libSDL-1.2.so.0 sources, im going to see if i can compile that. i'm pretty new to linux so bear with me a bit



edit

yea it seems that i cant compile the openal-alsa-emu10k1-1.2, i get the same error as you do...but i can compile the one that UT2004 gives you, but that one only gave me a slight increase (2fps)

1st, Install the build-essential package
2nd, if you'd like an easy way to fix this youself in the future without blindly installing unnecessary packages, install apt-file and search for the missing includes:

$ apt-file search usr/include/pthread.h
libc6-dev: usr/include/pthread.h
$ apt-file search usr/include/semaphore.h
libc6-dev: usr/include/semaphore.h
$ apt-file search usr/include/alsa/asoundlib.h
libasound2-dev: usr/include/alsa/asoundlib.h
$ apt-file search usr/include/ansidecl.h
binutils-dev: usr/include/ansidecl.h

All you needed to install was libc6-dev, libasound2-dev and binutils-dev

Wow, didn't even realize that. After doing a "sudo apt-get install libc6-dev" I was able to successfully compile the package. Thank you for your help.

Will let you know if I see an FPS decrease or increase.

[DarkManX4lf]

well i compiled it, and even tho there were errors, it spat o ut a module, when i used that module i noticed an avg 10fps in crease and a max 20fps increase so i would say its good...maybe if we get rid of those errors we can get more performance.


EDIT

i just tested the new module, and it seems fine BUT the volume seems to be very low, even tho i turned it up high in UT2004, when using the older module this wasnt the case....and i had the same errors as the above posted....hopefully we can get t hem fixed.
