Unsatisfied Link Error when swiching rendering modes.

[Raven]

Hello all again.
Since the new library spawned some issues on switching renderers in the demos, I thought it was a good time to ask for help regarding my issue.

It's when I press 'x' in the FPS demo (try to switch between rendering modes) that I get this error:

I did a search for this error on the forum, but found nothing except something regarding WebStart which I really made no sense of.

My run command specifies the path to the lwjgl library, so I don't get it>

java -mx700m -cp .:/Users/raven/Dev/3D/JPCT/jpctapi/lib/lwjgl-0.97/lwjgl.jar:/Users/raven/Dev/3D/JPCT/jpctapi/lib/jpct/jpct.jar JPCTDemo

I'm running on OS X 10.4.
Any ideas?

Cheers,

You have to include the native libs too. Either put them in the current directory (should work...) or use the -Djava.library.path=<your dir>-switch to tell the VM where to look for the native libs.

Sorry if I'm being a bother about this, but  tried both with no luck.

java -Djava.library.path=/Users/raven/Dev/3D/JPCT/jpctapi/lib/lwjgl-0.97/ -cp .:/Users/raven/Dev/3D/JPCT/jpctapi/lib/lwjgl-0.97/lwjgl.jar:/Users/raven/Dev/3D/JPCT/jpctapi/lib/jpct/jpct.jar JPCTDemo

Same problem. Are the native libs not the ones stored in the lwjgl folder? the .dll's?

Thank you for your patience.

They are, but for Windows. You have to use native libs for Mac. They can be found here: https://sourceforge.net/project/showfiles.php?group_id=58488
You may either upgrade the whole LJWGL-stuff (including the jars) that comes with jPCT (from 0.97 to 0.98 ) or simply download the 0.97 version for Mac and use the libs in the native-folder instead.

Hope this helps.

Oh, wow!
That worked! Thanks!
Actually I should have figured that the dll's were windows files  :oops:

Now my framerate is *alot* higher.

Thanks!
