Hi Jan, Iâm sorry but I will not even look at it :( nothing personal, I respect a lot the instantiations people and their product (and I know they will do a good work). Is just that I care a lot about Pharo being open source MIT and I do not want to pollute my code with something I might have seen elsewhere (and copyrighted elsewhere)⦠But of course, I can discuss my idea here and with whoever wants :) So, I have this idea who is very simple: keep structure offsets separately. Today all structure has something like this: height "This method was automatically generated" ^handle doubleAt: 17 height: anObject "This method was automatically generated" handle doubleAt: 17 put: anObject which of course does not work. with my idea this will become like this: height "This method was automatically generated" ^handle doubleAt: HEIGHT_OFFSET height: anObject "This method was automatically generated" handle doubleAt: HEIGHT_OFFSET put: anObject and HEIGHT_OFFSET can be initialised per session⦠or with a minimal intelligence per session with a âarchitecture changedâ verification. I think this is very easy to implement and will work⦠but of course I still didnât do anything more than think about⦠weâll see when I try to implement it :) Esteban

Hi Esteban,
Instantiations is also busy porting their VM to 64bits. They have already created a new API for OStructures so that the offsets are re calculated based on the platform alignment rules and the VM type [1].
I know Pharo is open source and VA Smalltalk is not. But a bit of cooperation should be possible I think. Both platforms benefit if libraries are easy to port and not re-inventing this wheel saves time.
Jan.

Hi,
With the latest 64bits VM (201611042126) and image (60282) UFFI is also looking good. I'm testing a small library of mine [1] to interface with LMDB [1], a memory mapped key-value database. Almost all tests are green. This is great progress!
Hi Jan,
did you have to change your UFFI definitions to match the 64bits version of your lib?
no. but structures do change (because of sizes, of course). Iâm thinking a way to define a generic representation (keeping offsets somewhere instead hardcoding it), but for now they have to be redefined for each platform.

I only ran into one issue, a PrimitiveFailed error with #basicIdentityHash in the SmallFloat64 class.
Cheers, Jan.

this is still not official (thatâs why is not in official place) so there are a couple of known problems:
- version format is different, and that breaks some things in image that depends on it to know what happens - command line is different and probably youâll need to play a bit with options (one or two dashes). - UFFI has some failing tests (but most of it works).
I would appreciate some help to report and/or fix the emerging problems.
cheers, Esteban

Hi all,
anybody knows how to get (and test) the 64bits version of the Pharo vm and image?
Thanks,
Thierry
