Pharo8 is pretty old :)

Hi Gulliermo, Have you any stats on what are the most used Pharo version?

The best I can propose is that you try compiling the VM without the JIT compiler. That will not give you optimum performances, but acceptable ones compared to Rosetta.

I’d suggest you try to compile using the branch pharo-9. That’s probably the oldest branch that is easy to build using cmake.

If the pharo-9 branch does not work for your image, then maybe you should check the branches (see the branches v8.x.x).

For installation/build instructions, please follow the readme instructions. If you find any issues, tell us, maybe there are cheap workarounds or fixes :).

Thank you for your hints. I try to move the codebase to Pharo9, if it is too cumbersome then I try to compile the VM without JIT. Cheers Davide

Hope that helps, Guille

Hi Guys, I want to use my old Pharo 8 image on an Apple Silicon (ARM64). I downloaded the stable VM for apple silicon http://files.pharo.org/get-files/110/pharo-vm-Darwin- <http://files.pharo.org/get-files/110/pharo-vm-Darwin-arm64-stable.zip>arm64 <http://files.pharo.org/get-files/110/pharo-vm-Darwin-arm64-stable.zip>-stable.zip <http://files.pharo.org/get-files/110/pharo-vm-Darwin-arm64-stable.zip> but it isn't working with my pharo8 image.

My old VM is working, of course, but I suppose it's because of Rosetta... and the performance is not optimal.

Any other solution?

I do not think that we have a solution. I’m sorry but we decided that we cannot garantee that old Pharo version can run on Apple Silicon just because of engineering effort. With Pharo we are always trying not to trade the past for the future but this is difficult.
