I've fixed the color table problem in CVS. I don't think this is related to the arithmetic exception though. When you get the stack trace, could you print the 16 values in the matrix passed to _mesa_LoadTransposeMatrixdARB()? My guess is one of the double-precision values is outside the range of single precision and we'll have to add appropriate checks in _math_transposed().

When printing the matrix the first value in the matrix was huge (10^100). I then realized that it might me a problem with the different floating point representations on VMS. I used to compile the java3d shared library with /float=IEEE, whereas the default mms files from mesa do not specify any flag, which means that the VAX G_FLOAT type is used. Now it looks like the two different floating point types in the two shared libraries were causing the problems. When recompiling the mesa library with /float=IEEE, then it works perfectly fine. I would suggest to include this compiler flag into the mms files, because IEEE is more standard than the VAX floating point representation. thanks again for your quick help. Thomas I've added a note about this to the README.VMS file. Closing the bug now. |

I'm still trying to port Java3D to OpenVMS with Mesa 6.2.1 as OpenGL implementation. When the Canvas3D should be displayed on the screen the program crashes. Shortly before crashing I get this Mesa implementation error. Unfortunately I was not able to debug the shared libraries, because when the debugger is running, Java can not lock the drawingSurface and is stuck (maybe problem with threads??). So I can't get to the problem code with the Debugger. I try now to follow the path with printout messages, but I do not understand very much about the drawing mechanisms. So maybe this implementation error is not even related to the segfault I get. Concerning the implementation error, I think that the _mesa_ColorTable is called with the wrong target (GL_PROXY_TEXTURE_COLOR_TABLE_SGI), but again I have no idea, where the _mesa_ColorTable is called and why it is called with that target. Some light into this dark area of porting java3d to OpenVMS is very appreciated. Please find below the output messages and the segfault I get. best, Thomas CUSTER> java "JavaVizObj" Unknown host: WSA200 Java 3D [dev] 1.3.3-pre1-0508221737-experimental 22 Aug 2005 17:37:05 CEST Initializing Java 3D runtime system: version = 1.3.3-pre1-0508221737-experimental 22 Aug 2005 17:37:05 CEST vendor = Sun Microsystems, Inc. specification.version = 1.3 specification.vendor = Sun Microsystems, Inc.
