Its prolly me as usual. But I have checked my version 4 times now. I am trying to make my soundManager work. But when I ttry to set my listener. This happens

The line that fails...

AL10.alListener(AL10.AL_POSITION, listenerPosition);

Stacktrace:
java.lang.UnsatisfiedLinkError: nalListenerfv
	at org.lwjgl.openal.AL10.nalListenerfv(Native Method)

does PositionTest work? - it uses AL10.alListener. It works here at least...

Is AL created? if it isn't, no native stubs will be linked into the jvm.

and related to that - shouldn we auto create AL too ?

Yes, we should. What happened to all the System.loadLibrarys we used to have all over the place??? It's a bug in our code, for sure.

Not necessarily. We don't need loadlibs in classes like GL11, GL12, .., AL10 etc. because the symbols are loaded from another class (Window in nCreate and AL in create). It's a feature - you don't load the native stubs if there's no native function pointers to gl/al. Doing so (the old behaviour) would simply transform the UnsatisfiedLinkError to a native crash on a NULL function pointer.

Ah, fine. Still needs fixing in AL though.

Why? There's a:

       static {
                Sys.initialize();
        }

which does (among other things)

               System.loadLibrary(LIBRARY_NAME);

Hm. So why's UnsatisfiedLinkError: nalListenerfv happening?

Cas

elias · April 23, 2004, 14:35:56

Either there's a bug in LWJGL (which is unlikely if another OpenAL test that uses alListener is working) or al hasn't been created succesfully.

Well I am away for this weekend so I can't test on the code I made. I am almost sure I create AL.. I'll try to test

I had 1 line before OpenAl create....
