Closing button deactivated
by Damien Cassou 12 Oct '07

12 Oct '07

Hi, after having compiled squeak-vm for Unix from Svn, the closing button of the squeak window does nothing at all. I wonder if it is related to the problem with -Werror and the useless function declaration. Bye -- Damien Cassou

oops to zero
by Keith Hodges 10 Oct '07

10 Oct '07

I am attempting to zero all ooP pointers before writng an image to disk. I have added the following code to Interpreter-#writeImage: writeImageFile: imageBytes ... self adjustAllOopsBy: (0 - memory). self writeImageFileIO: imageBytes. self adjustAllOopsBy: memory. ... I managed to build a unix version of the vm with this change but it did not work as hoped. Starting an image saved with this vm crashes giving a bus error. any ideas? I am also unable to find any documentation on generating the .app version of the unix vm for Mac OS X. thanks in advance Keith _ To build this into squeak: Loaded 3.9.8-12 stuff from http://www.squeakvm.org/unix/release/ I have the current trunk obtained by: svn co http://squeakvm.org/svn/squeak/trunk squeak I have http://www.squeakvm.org/unix/release/unix-3.9-12.image.gz http://www.squeakvm.org/unix/release/unix-3.9-12.changes.gz http://www.squeakvm.org/unix/release/unix-3.9-12.vmm.config I am on Mac OS X, using John 's OS X VM 3.8.18beta1U The above config file is not visible by the VMaker Tool 'load' button, when I save my own config, that one is. Clicking the platform button: UnixOSProcessPlugIn-#isResponsibleForThisPlatform calls Smalltalk osVersion rather than SmalltalkImage current.

Re: [Vm-dev] Benchmarking in the Context Step Simulator

This clearly belongs in squeak-dev, not here. I will cross-post it.

Benchmarking in the Context Step Simulator
by André Wendt 08 Oct '07

08 Oct '07

Hi, when trying to execute ContextPart tallyInstructions: [MacroBenchmarks run] I get the error message "context not in process." A similar problem has been reported at <http://bugs.squeak.org/view.php?id=5716>. Are there any benchmarks that are more complex than Integer>>#benchmark and Integer>>#benchFib but still work in the simulator? Or, what other options do I have to analyze the executing instructions? Thanks, André

Listserver problems with vm-dev?
by Andrew Gaylard 07 Oct '07

07 Oct '07

I see in the vm-dev list archives at http://lists.squeakfoundation.org/pipermail/vm-dev/2007-October/thread.html that from my last two posts, "A non-text attachment was scrubbed". No problem -- many lists do this with files that are attached to messages. Presumably this is a spam-mitigation measure. But where's the *body* of the message? It's gone. In other words, mailman has removed it, either when delivering the mail to the list recipients, or when archiving the message. Please can one of the list admins check this out? Thanks, Andrew.

patch: fix build problems on Solaris
by Andrew Gaylard 06 Oct '07

06 Oct '07

Hi, This patch fixes 4 problems which prevented the VM from building on Solaris/SPARC. They shouldn't cause problems for other platforms (famous last words), so please would someone (Ian?) confirm this before checking in. The problems fixed by this patch are: 1. "sun" is already defined by some header or other in Solaris; I've changed it to s_un. 2. AF_LOCAL isn't defined on Solaris. W Richard Stevens' "Advanced programming in the Unix environment" says that AF_UNIX is more standard anyway. 3. Solaris' feof() call really wants a FILE*. 4. A missing prototype is added for sound_AvailableSpace(void) With this patch, the VM builds and runs fine if built with gcc-3.4.3. I've checked both the stock 3.9a-7024 image as well as the etoys image. (My motivation for this whole exercise is to fix the problems with audio under Solaris for my young daughter to use etoys: the first sound plays, but after that, no sounds ever play.) With gcc-4.2.1 and -O2, the VM won't even start up (complains about a missing vm-display-X11, even though it's there). With gcc-4.2.1 and no -O2, the VM starts, runs for a short while, and then cores with a bus error. gdb shows a corrupt stack. I'm about to build gcc-4.1.2 and give it a spin building the VM to try to track this down. But I do suspect bad code generation with gcc-4.2.1.
