OPENAL and Linux

Hi everybody,

and once again a silly (?) question...  :D

we are now implementing the first sounds in our slot machine and of course we want to use openal.

on windows it works fine but on linux we always get an error when accesing the native library. i put the liblwjgl.so in the library path and (i suppose) the library gets found but crashes when trying to reproduce sound.

i was wondering if there's missing a library since the windows lwjgl version comes with 2 DLLs and the linux version only has the liblwjgl.so

i suppose we need the openal driver/library for linux but i read in this tutorial
http://www.lwjgl.org/documentation.php?page=tutorials/openal/devmaster/lesson1
that the linux contributor of openal isnt "alive" anymore.

does anybody know how to get the openal library/driver for linux?
or are we just completely wrong??? (also quite possible)  :D

I'd like a stack trace of the crash and OS/LWJGL version, please :-) Oh, and the program you're running (did you try the standard tests?)

chriddel

thanks matzon,

but we are still crashing...
(An unexpected exception has been detected in native code outside the VM) - same error as before.  :cry:

do we need to specify some -Djava.library.path?

chris

elias

Could you give a complete crash log? Most of the time a stack trace is included. It helps tremendously.

chriddel

we put the libopenal.so in the same folder (where all our jar files are located). i suppose we dont need to specify -Djava.library.path=. in this case, no?

thanks elias, so here we go...

ah, i almost forgot:
the program that is crashing is the first openal tutorial from lwjgl.org:
http://www.lwjgl.org/documentation.php?page=tutorials/openal/devmaster/lesson1

...so i think that should work fine ...  :roll:

chris

elias

Hm, that's weird, the alBufferData is not the first OpenAL call, so some AL is working. Could you check if the buffer given to alBufferData (waveData.data) is non-null and isDirect() is true? I've added checks for that in CVS but that won't help you now. What version of LWJGL are you using?

- elias

chriddel

hi elias,

I'll check this in a few hours (i cant use the linux pc right now). thanks a lot so far.  :D

i am using lwjgl 0.9 (which is declared to be stable)

No worries, I just wanted to know which version you are using to help me narrow down the problem.

- elias

chriddel

sorry elias,

but where is this isDirect() function?? I can't find it  :oops:

chris

rgrzywinski

java.nio.ByteBuffer.isDirect()

chriddel

finally...

ok i just tested the new version and it crashes exactly the same way.
the bytebuffer IS direct and wavedata IS NOT null.

so it should have worked ...  :cry:  ... but it has NOT.

maybe creative changed something in the openal library?
- dont think so but i dont know what to do now...

would be nice if anyone could send me a precompiled libopenal.so file.
or i could prepare a webstart - maybe i did something VERY silly and i dont see the stupid error. but then again: it wouldnt work in windows - wouldnt it?

so most probably its a configuration problem on the linux pc. we use red hat 9, sis motherboard, ati radeon 9200.

somebody has any advice??? help!!  :D

chris

elias

You could always try Alien Flux or Super Elvis if you want to test openal.
Do you have an email address I can send the build to?
