Don, I did some testing of matlab with different versions of the X libs by exchanging successively the versions from fink's xfree86 with those supplied by matlab with their X11 installation. What I found is the following: If I replace the 3 libraries libX11.6.2.dylib libXext.6.4.dylib libXp.6.2.dylib by their matlab-supplied versions, then "opengl info" and "bench" and other 3D graphics related commands no longer freeze matlab. Replacing libGL or libGLU has no effect whatsoever. Nor can one replace less than these 3 together, otherwise X11 doesn't run any more. If you wish, I can send you these 3 libs (500kB as tar.gz) so you can see for yourself. I have no idea what has changed between the version supplied by matlab (which is probably the original xfree86-4.2.0 from xfree86.org, but I haven't checked this yet) and the versions produced by fink in xfree86-base-4.2.0-11 and xfree86-base-4.2.99.1-0.20020810 Unfortunately matlab is closed source, so one cannot look what they are doing to call the opengl stuff. Another funny thing is that "opengl info", when it is not freezing matlab, gives two different reports depending on which version of *XDarwin.app* one is using, the one supplied by matlab (which seems to be the same as the one inside OroborOSX), or the one from fink. The first one says >> opengl info Version = 1.2 Mesa 3.4.2 Vendor = VA Linux Systems, Inc. Renderer = Mesa GLX Indirect MaxTextureSize = 2048 Extensions = GL_ARB_multitexture GL_EXT_abgr GL_EXT_blend_color GL_EXT_blend_minmax GL_EXT_blend_subtract and the second one >> opengl info Version = 1.3 Mesa 4.0.2 Vendor = Mesa project: www.mesa3d.org Renderer = Mesa GLX Indirect MaxTextureSize = 2048 Extensions = GL_ARB_multitexture GL_ARB_imaging GL_EXT_abgr GL_EXT_blend_color GL_EXT_blend_minmax GL_EXT_blend_subtract But again, this difference has nothing whatsoever to do with the problem of freezing. -- Martin ------------------------------------------------------- This sf.net email is sponsored by: OSDN - Tired of that same old cell phone?
