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.

no.
but structures do change (because of sizes, of course).
I��m 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.
