The normal OS for Pi is Raspbian, which is a Debian linux derivative, so use the unix build setup. RISC OS might actually be more fun for developing a GPIO interface, being less of a pain when it comes to low-level hardware access - but not of use to anywhere near as many people.

I already explained in a message to you Dec 27th where you can get the source code and the current VMMaker and instruction. Which parts aren’t making sense or are not working?

(Note to Dave - your swiki page - http://wiki.squeak.org/squeak/6177 - is a tad out of date though mostly ok. I suspect some mentions of the complications caused by having the plain interp and two oscog variants in the one repository might be good.)

http://source.squeak.org/VMMaker -> VMMaker (not VMMaker.oscog or VMMaker-oscog) BUT load it with the ‘update’ as described by Dave on http://wiki.squeak.org/squeak/6177 and then update it as described.

Only as handled in the ‘update’ configuration; that handles all of it.

Described on  http://wiki.squeak.org/squeak/6177 as above

n/a

Never test for an error condition you don't know how to handle.
