Re: ARM64 VM for Manjaro/Arch

by Patrick Henning

Pablo, thanks so much for your help! I was able to build the VM successfully using the linked instructions, however when I try to use it to run either a Pharo 80 or Pharo 90 image it does not work. I think the following bits from 'PharoDebug.log' may be relevant (full contents here: https://pastebin.com/9sk400WW) ``` =============================================================================== Notice: Your VM is too old for this image. Please download the latest VM. =============================================================================== THERE_BE_DRAGONS_HERE Your VM is too old for this image.

Hi Patrick, we don't have a binary version of the VM yet. We are trying to use OBS to generate the packaging for the different distributions and architectures. This is working for Arch-like distributions for x86_64 but not for ARM (v7 nor v8). I have tried today to see if it is our problem or if it is only that OpenBuildService still does not support it. In the meantime, I have added instructions to build the VM locally from the sources already generated. You can check it there: https://github.com/pharo-project/opensmalltalk-vm/wiki/Compiling-in-Manjaro… If still, you are not able to build it, please let me know, and I can try to pass you a binary version of it. I want to have binary packages for most of the distributions using the dependencies locally, but we need to manage the amount of manual work.

ARM64 VM for Manjaro/Arch

Hello, I am writing to ask how I can access the beta ARM64 VM for Arch-type Linux (I am using Manjaro in particular). Thank you! Patrick

I never thought of that implication - if ivars are proper objects (is that now applied?) would this issue go away (an ivar would just get a new parent)? This is a very interesting problem, as its a type of transaction, and I never though of it that way - its easy to think of it as just dumb code - but in effect it isnât.

Wonderful to have progress on this important topic - thank you! Sorry I haven't been following closely (maybe you addressed it already), but pushing up instance variables has a dangerous limitation - instances lose any data held in that var. I guess it's because it's deleted from the subclass prior to adding to the superclass to avoid duplicating. One solution would be to add a var to the superclass with a mangled name, copy the data for all instances, remove the var from the subclass, and then rename the mangled var. ----- Cheers, Sean -- Sent from: http://forum.world.st/Pharo-Smalltalk-Developers-f1294837.html
