Re: [Vm-dev] [squeak-dev] Porting my programs from Squeak 3.10.2 to 3.5

Hi Trygve, > On Apr 5, 2020, at 2:47 AM, Trygve Reenskaug <trygver(a)ifi.uio.no> wrote: > > I'm struggling with a new .image3 extension. It seems that Squeak Cog Spur Virtual Machine actually KNOWS that all images have the .image extension. This seems to mean that I can't run two different Squeak generation images within the same OS instance. there’s no restriction on running multiple kinds of image or multiple images or multiple instances of the same image. One can always drop an image on the right vm, or manually launch a specific vm with a specific in a shell. The issue is only having double clicking select an appropriate vm for the image, and for that you’re right that one needs a wrapper. Pharo has a wrapper implemented in Smalltalk, PharoLauncher, that could be adapted. VisualWorks has a small wrapper and an ini file, VisualWorks.exe & VisualWorks.ini IIRC (know it? I wrote it). It wouldn’t be hard to implement the wrapper solution. I’ll try and get that done in the next few days. But then it has to get pushed through to production, to be built using some kind of CI. And of course it makes sense on all platforms. > > I'll try running my 3.10.2 under Cog Spur Virtual Machine. I hope it works. It won’t. Spur 32-bit VMs are the only VMs that can run 32-bit Spur images, Spur 64-bit VMs are the only VMs that can run 64-bit Spur images, etc. it isn’t just a matter of converting each individual object. There are bytecode set, closure design, identity hash and object enumeration method, and other Smalltalk-level differences that mean automatically converting images is impossible. Converting between 32-bit and 64-bit Spur images *is* automatable and there is a program (a Spur image) I should package up to do it. But it takes a few seconds and requires VMMaker, so it is not small, and so is not something to add the the vm and have some images takes seconds to launch instead of milliseconds. > > > On 04-Apr-20 9:13 PM, tim Rowledge wrote: >> We were discussing this with regard to the 5.3 release but didn't have time to sort out.

vm-sound-pulse
by stes 02 Apr '20

02 Apr '20

VM: 5.0 branch 'solaris' In the file platforms/vm/sqUnixMain.c there is a list of vm-sound- plugins to try. In my case on Solaris the vm-sound-pulse works best for me, so I've put it first in the list: { &soundModule, "sound", "pulse" }, { &soundModule, "sound", "OSS" }, { &soundModule, "sound", "MacOSX" }, { &soundModule, "sound", "Sun" }, { &soundModule, "sound", "ALSA" }, { &soundModule, "sound", "null" }, The vm-sound-OSS also works well. The vm-sound-Sun does not work for me, but I think it is old code for Sun SPARC so I should test it sometime on SPARC someday although that Solaris has moved to 'pulseaudio'. Is it reasonable to put "pulse" on top of the search list ?? It is also possible to command-line start squeak with -vm-sound-pulse or -vm-sound-OSS to select another plugin ... but given the fact that vm-sound-pulse works (at least for me) I thought maybe it makes sense to put it first in the search list. How is this on other platforms ? -- Sent from: http://forum.world.st/Squeak-VM-f104410.html
