For the binary-challenged, I am sure some kind soul will post compiled versions somewhere...!
(I ALWAYS struggle with build.bat, missing files, environment variables, and the like...)
Take care,

The Cogit currently supports only x86 and the floating-point primitives and parts of the platform support code depend on SSE2. I hope members of the community will attempt to port it, e.g. to ARM, PowerPC and x86-64.
Now before anyone asks, it's very doubtful you will see Cogit on the iOS series of operating systems (iphone/ipad). I have had detailed discussions with the Apple Security team since their goal is to prevent user level code from doing dynamic code generation.
mmap for example won't return a page of memory that is executable.
Let's say the probability of getting Apple to change their minds on this is zero.
However I'll look into the StackInterpreter for the Macintosh 5.x VM and the iOS flavour, mind if anyone wants to do that chore early then they should ping me.
