Joal tutorial crashes

[troggan]

I am just starting to learn OpenAl to use it in my game.
I downloaded the first Tutorial and installed the OpenALwEAX.exe. If I run the first Tutorial, it crashes.
What am I doing wrong?

Can you tell me a little more about your configuration? (WinNT/Win2000/WinXP, Audio card, memory,etc)

I also am crashing outside the VM.

I'm running Windows XP on a Dell system.  The sound card is a "SoundMAX Integrated Digital Audio" chip by Analog Devices, Inc.  The system has 512 megs of RAM.

I installed OpenAL from ftp://opensource.creative.com/pub/sdk/al_beta_0_6.exe.  I tested the install with the demos from ftp://opensource.creative.com/pub/sdk/ALTests.zip and they worked successfully with the Default (NULL) device, but not any of the other devices.

I also noticed that the joal.jar file in the tutorials is different from the main download, incluing a ALut class the main does not.  That took a little while to figure out since I don't use ant to build.

Crash info for Lesson1:

I installed OpenAL from ftp://opensource.creative.com/pub/sdk/al_beta_0_6.exe.  I tested the install with the demos from ftp://opensource.creative.com/pub/sdk/ALTests.zip and they worked successfully with the Default (NULL) device, but not any of the other devices.

ALut.init() now calls ALC.alcOpenDevice(null) rather than ALC.alcOpenDevice("DirectSound3D") on windows. Also, alcOpenDevice(null) was causing the VM to crash. This has also been fixed. Since you were apparently having problems when specifying a non-null device on you machine these issues may be related. So you may want to download the newest version of the demos and try again. Please let me know (or better yet, file a bug with the Issue Tracking Tool) if you are still having problems.

[Caoimhin]

I've successfully got Lesson1 running now.  By installing the latest joal nightly build and droping them into the ext directory of the JRE I'm using, the application seems to run fine.

[Athomas Goldberg]

Wahoo!!! One down, 775 more platform configurations to go. Let me know if things stop working for you.  

[Athomas Goldberg]

I've added a poll to the forum in an attempt to get an assessment of how stable the current version of JOAL is on different windows platform configurations.  Please follow the instructions on post #1 of the poll before voting. Your participation in this survey will be greatly appreciated, and go a long way toward getting us to a stable release. Thanks in advance!

Dear All,

I downloaded the tutorials and JoAL yesterday (and the latest OpenAL SDK), recompiled everything, pass the tests (in the SDK and JoAL) but the tutorial are crashing and I have the same error output as listed in previous emails.

But what is odd is that if I run the samples from a DOS box, then they work. If I run them from an IDE, then they crash. I am on WinXP, I don't use EAX, use Eclipse IDE.

I tried to trace the issue. The problem seems to be in Java_net_java_games_joal_ALCImpl_createContextNative when it calls alcCreateContext(). That's where the JVM crashes.

In lesson 1, on a DOS box, it crashes when I quit in ALut.aluExit() because in the first call, alc is null! Weird indeed as all other lessons work fine but only from a DOS box.

Thanks for your help,

Mike

[mikeseven]

That might help:
when I trace the issue on a DOS box, the DLL creates the device in openNativeDevice(), the java object it returns has address: a0c384.
When DLL's createNativeContext() is called, in the DOS box, the device address is different. On Eclipse IDE, the address is the same.

So strangely enough: when createNativeContext() is given the same Java device object address, it crashes. When the address is different, it works.

OK I found the problem.
This was not related to JoAL but to an old joal.jar in Eclipse classpath.

Sorry for bothering you.
