Yep, Ken, that change to BuildMipmap.java fixed it. Thanks!

BTW, I really want to submit a test case, but can't easily build one out of my code (it's way too big and involves C and Java in addition to the jogl stuff). Sorry about that.

Andy

I just tried my code with JOGL 1.1b12 and there's been progress! With the java version of the glu library, some of my mipmaps are built correctly!

The ones that fail are mipmaps made from 1x1 textures. There's a bug in the algorithm in BuildMipmap.java:gluBuild2DMipmapLevelsCore() when width, height, widthPowerOf2 and heightPowerOf2 are equal to 1. We enter the if statement (if (width == newwidth && height == newheight)) and get down to the switch(type) statement where I'm passing in GL.GL_UNSIGNED_BYTE, so we call HalveImage.halveImage_ubyte() with width and height = 1. But halveImage_ubyte() has an assertion that width and height can't both be 1 so we fail.

There's obviously a bug in the control flow here. Here's a stack trace of the error:

Just wanted to report that Chris Cooper's MacOSX patch did the trick and everything compiles now on OSX 10.3.9.

Sorry, here's the full build log for both jutils, then jinput. The jinput.jar file is created. The ant script copied it to jinput/plugins/DX8/lib. That seems like the wrong place for an OSX build, no?

Added -Djogl.glu.nojava makes my program succeed. And I miswrote earlier. The original texture is 128x128, not 256x256.

According to the Java code in mipmap.Mipmap.closestFit() in Mipmap.java:259, the GL_PROXY_TEXTURE_2D argument to glTexImage2D() is passed explicitly and on purpose.

I haven't used JOGL's TraceGL before. I'll read up on it and figure out how to use it.

I'll also report this as a bug on the Issue tracker.

When I try to compile the nightly build of jinput on OSX (from March 25, 2005) jinput-1.1.0-b04-src.tar.gz, I get this compile error. Is there any updated source code (cvs HEAD shows the same problem) that actually compiles?

I'm having a problem building a 2D mipmap on JOGL 1.1b10 on OSX 10.3.9 (Powerbook G4 ATI Radeon 9700 card). No matter what image I send to the function, it keeps giving me a GL_INVALID_VALUE exception inside of an internal call to glTexImage2D. Here's the code:

           glu.gluBuild2DMipmaps( texture.target,
                                      texture.dstPixelFormat,
                                      texture.width,
                                      texture.height,
                                      texture.srcPixelFormat,
                                      GL.GL_UNSIGNED_BYTE,
                                      texture.byteBuffer );

where, texture.target is GL_TEXTURE_2D, dstPixelFormat is GL_RGBA, srcPixelFormat is GL_RGBA, width and height are 256 and byteBuffer points to image data loaded from a PNG file (which looks ok with Preview).

The error I get is this:

Any idea what I can do to debug this further? This works perfectly with the same JOGL on a PC running WinXP with an NVidia card.

Thanks,

Andrew

Thanks for posting a new build, even if there's no real changes.
I tried compiling JOGL myself, but ran into the problem listed in my first message in this thread (that was unresolved by the helpful suggestions of the other replies). I'm less than amazed by ant, esp. re: classloaders and separating different java programs in the same JVM image (which is obviously where I'm having problems).

The stack trace was cut and pasted in, no alterations were made.

If you download the July 17th build from the File Sharing section of this website and run javap -c on net.java.games.jogl.impl.macosx.JAWT_MacOSXDrawingSurfaceInfo, you'll see a cocoaWindowRef() method.

Compiled from JAWT_MacOSXDrawingSurfaceInfo.java
public class net.java.games.jogl.impl.macosx.JAWT_MacOSXDrawingSurfaceInfo extends java.lang.Object {
   public static int size();
   public net.java.games.jogl.impl.macosx.JAWT_MacOSXDrawingSurfaceInfo();
   public net.java.games.jogl.impl.macosx.JAWT_MacOSXDrawingSurfaceInfo(java.nio.ByteBuffer);
   public java.nio.ByteBuffer getBuffer();
   public net.java.games.jogl.impl.macosx.JAWT_MacOSXDrawingSurfaceInfo cocoaViewRef(long);
   public long cocoaViewRef();
   public net.java.games.jogl.impl.macosx.JAWT_MacOSXDrawingSurfaceInfo cocoaWindowRef(long);
   public long cocoaWindowRef();
   public net.java.games.jogl.impl.macosx.JAWT_MacOSXDrawingSurfaceInfo cgContextRef(long);
   public long cgContextRef();
}

Granted, there's also a cocoaViewRef() method.
And, if you disassemble the net.java.games.jogl.impl.macosx.MacOSXOnscreenGLContext class, the lockSurface() method calls cocoaViewRef(), not cocoaWindowRef(). So, I can't explain what's going on. All I know is that my error is quite repeatable.

There's no other jogl in my CLASSPATH and none in /Library/Java/Extensions.

Perhaps someone could post a more up-to-date build, and perhaps this problem might go away?

Thanks.

Andy

Nope, it's not in my /Library/Java/Extensions folder. It's in /usr/local/pkg/antlr-2.7.2/share/antlr-2.7.2/antlr.jar.

I did try downloading the JOGL build from July 2 and that works for me. I think the telltale sign here is the reference to cocoaWindowRef() which doesn't exist in OSX 10.3's jawt_md.h file (replaced by cocoaViewRef()). Maybe the july 17th build was a half-hearted attempt at OSX 10.2 compatiblity?

I've tried to compile JOGL on OSX (10.3) and I've run into big problems. I've got ant and antlr installed, but when I do
ant macosx
It runs through all the build steps but fails java.generate:
java.generate.check:

BUILD FAILED

I've set antlr.jar variable in host.properties to the antlrall.jar from the antlr-2.7.2 download (antlr.jar didn't work) and antlr successfully ran on a few things, but then fails here. I've verified that antlrall.jar does have antlr.TokenStreamException.class in it.
I'm using ant 1.5.3 that I built from source.

What can I do? I've tried using the prebuilt jogl.jar file from july 17, but that doesn't work on my system (gives the following error on the first paint call:
