Problems with Windows 32bit

Hi,

there might be a problem with the 32bit natives for windows. If I run a JOCL-project under 32bit environment i'm getting:

Exception in thread "main" java.lang.UnsatisfiedLinkError: com.jogamp.common.os.WindowsDynamicLinkerImpl.LoadLibraryW(Ljava/lang/String;)J

With 64bit there seems to be no problem.
Could you possibly take a look if you get the same issue?

Regards and thanks in advance,
Philipp Stelzer

Hello Philipp,

I'll take a look. We have a win64+ 32bit jvm build/test server in our cluster and it runs fine on that setup. I should run some tests manually on win32.

thanks,
michael

installed win7/32bit + oracle jdk in virtual box and JOCL it runs fine so far. Was not able to reproduce the UnsatisfiedLinkError.

btw a webstartable CLInfo demo is here: http://jogamp.org/jocl-demos/www/
(currently only deployed for windows and linux)

I first tried it with WinXP 32bit + Oracle JDK, but couldn't get it to work because of the UnsatisfiedLinkError. Both, the aggregated builds from jogamp and my own builds led to the same.

Later I used Vista 64bit with Oracle JDK 64bit and there was no problem executing the project. Switching to 32bit led to UnsatisfiedLinkError again.

The XP and Vista systems are completely different machines, so I thought there could be a problem with the 32bit jocl.dll. But if it works on your systems, the error might be with me.

The complete exception is as follows:

Exception in thread "main" java.lang.UnsatisfiedLinkError: com.jogamp.common.os.WindowsDynamicLinkerImpl.LoadLibraryW(Ljava/lang/String;)J
        at com.jogamp.common.os.WindowsDynamicLinkerImpl.LoadLibraryW(Native Method)

So, I don't understand why it doesn't work with 32bit, but with 64 without problems...

Any suggestions?

Philipp

does the webstart CLInfo demo already trigger the exception?

thanks,
michael
