Resizing won't help, there is just the garbage. Display depth change: no effect. Hmmm, however, Squeak is there in the process list and even the cursor changes to "Squeak-style" when over the Squeak window. Christian Eitner

Unix B3D Acceleration
by Joshua 'Schwa' Gargus 01 Jul '02

Hi, I have been unable to build a VM with working B3D acceleration from either SourceForge or Ian's sources. With the SF sources, I wasn't able to build a VM at all. There were a ton of warnings about control reaching the end of a non-void function. The errors that stopped the build process were B3DAcceleratorPlugin/sqUnixOpenGL.lo: In function `glGetIntProperty': /home/schwa/squeakvm/build/../platforms/unix/misc/../../../platforms/unix/plugins/B3DAcceleratorPlugin/sqUnixOpenGL.c:330: multiple definition of `glGetIntProperty' B3DAcceleratorPlugin/sqOpenGLRenderer.lo:/home/schwa/squeakvm/build/../platforms/unix/misc/../../../platforms/Cross/plugins/B3DAcceleratorPlugin/sqOpenGLRenderer.c:654: first defined here /usr/bin/ld: Warning: size of symbol `glGetIntProperty' changed from 909 to 547 in B3DAcceleratorPlugin/sqUnixOpenGL.lo B3DAcceleratorPlugin/sqUnixOpenGL.lo: In function `glSetIntProperty': /home/schwa/squeakvm/build/../platforms/unix/misc/../../../platforms/unix/plugins/B3DAcceleratorPlugin/sqUnixOpenGL.c:361: multiple definition of `glSetIntProperty' B3DAcceleratorPlugin/sqOpenGLRenderer.lo:/home/schwa/squeakvm/build/../platforms/unix/misc/../../../platforms/Cross/plugins/B3DAcceleratorPlugin/sqOpenGLRenderer.c:709: first defined here /usr/bin/ld: Warning: size of symbol `glSetIntProperty' changed from 1134 to 753 in B3DAcceleratorPlugin/sqUnixOpenGL.lo collect2: ld returned 1 exit status make: *** [B3DAcceleratorPlugin.la] Error 1 Giving up on that, I downloaded Ian's sources and gave them a try. I tried both using his tree as-is, and with a src/ directory generated by VMMaker. With VMMaker, I tried to build B3DAcceleratorPlugin as both an internal and an external plugin. In all 3 cases, the result was a working VM without B3D hardware acceleration. The problem is the failure of the line p= interpreterProxy->ioLoadFunctionFrom("stDisplay", NULL); in sqUnixOpenGL.c One confusing thing is that stDisplay doesn't seem to be a function. Is some initialization function supposed to stash stDisplay (the one from sqXWindow.c) in a primitive table so that the accelerator plugin can find it? If so, this isn't happening. Help! Joshua

URGENT WARNING -- Don't snapshot! (was: "What is this error?")
by Scott Wallace 01 Jul '02

01 Jul '02

It appears that the latest official 3.3alpha and 3.2gamma images both have a significant, and perniciously dangerous, bug, which seemingly arrived in update 4897. Until this bug is fixed, it is *very dangerous* to be using any image that has update 4897 in it, because each time you try to snapshot such an image ("save", "save and quit", etc.) you stand a good chance of losing the image. Thus, ironically, the only way to assure that you won't lose such an image is never to save it. Which however makes development work problematical. Anyone who has not recently updated 3.3alpha past 4889 or updated 3.2gamma2 past 4889 or started using 3.2gamma3 is advised to hold off on doing so. Up-to-date 3.3a and 3.2gammaX images will all be in a very dangerous state in which to save them is potentially to lose them. Stay tuned... -- Scott PS: Reverting method ProcessorScheduler class.idleProcess *appears* to circumvent the problem.
