java.lang.UnsatisfiedLinkError: nglGetIntegerv

[OhlWedderReife]

Hello!

I am currently playing around with the excellent LWJGL library and I stumbled over the following "problem":
When I do the following...

try {
               IntBuffer ib;
               ib = BufferHelper.newIntBuffer(16);
               GL11.glGetInteger(GL13.GL_MAX_TEXTURE_UNITS, ib);

               maxTextureUnits = ib.get(0);
           } catch (Throwable e) {
               throw new RenderException("Could not query maximum texture unit count.", e);
           }

...I get this error...

owp.gfx.render.RenderException: Could not query maximum texture unit count.

   ... 27 more

The native sources seem to provide the needed function, though.
Do I miss some important point?

I am using version 0.92.

Thanks a lot for your help!

Maybe my LWJGL initialization code will be helpful:

public synchronized static void initializeWindowed(
           String title, int width, int height, int minBpp, int minAlpha, int minDepth, int minStencil,
           int minSamples, boolean vsynch)
           throws LWJGLException {

       Display.setTitle(title);
       Display.setFullscreen(false);
       Display.setVSyncEnabled(vsynch);
       Display.setDisplayMode(new DisplayMode(width, height));
       Display.create(new PixelFormat(minBpp, minAlpha, minDepth, minStencil, minSamples));

       initializeInputs();

       initialized = true;
   }

private static void initializeInputs() {
       try {
           Keyboard.create();
           Keyboard.enableBuffer();
           Keyboard.enableTranslation();

           hasKeyboard = true;
       } catch (LWJGLException e) {
           if (logger.isEnabledFor(Level.INFO))
               logger.info(Str.format("Could not create Keyboard input."), e);

           Keyboard.destroy();
           hasKeyboard = false;
       }

       try {
           Mouse.create();
           Mouse.enableBuffer();
           Mouse.setGrabbed(true);

           hasMouse = true;
       } catch (LWJGLException e) {
           if (logger.isEnabledFor(Level.INFO))
               logger.info(Str.format("Could not create Mouse input."), e);

           Mouse.destroy();
           hasMouse = false;
       }

       try {
           Controller.create();

           hasController = true;
       } catch (LWJGLException e) {
           if (logger.isEnabledFor(Level.INFO))
               logger.info(Str.format("Could not create Controller input."), e);

           Controller.destroy();
           hasController = false;
       }

Thanks for your patience once more as I get the feeling that my problem has something to do with me doing some real stupid error... :shock:

You don't need to create the input. It is done automagically. Other than that, whats your graphics card, os etc.

Oh shame on me! I just realized that I have a real stupid error in my code.
My JUnit test case that triggered the error simply did not call the initialization code! :oops:
I have put it in, now it works fine (hey I happen to have 8 texture units available   ).
Sorry for wasting your time and thanks for your quick answer!
