I'm trying to develop squeak virtual machine on Raspberry pi. I need to create a plugin to access the GPIO. My problem is that the squeak of rbp not have the sources of the plugins even brings vmmaker.
Someone suggested try to download sources from squeakvm.org. But i don't know wich version is for raspberry pi, none is indicated for rbp. will be riscos version ?
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?
My description -
You need the tools for C development on a Pi. You’ll need to apt-get etc for cmake, subversion & libX11-dev, plus possibly others I’ve forgotten.
The vm code is stored at squeakvm.org, read the pages there on how to svn checkout the right stuff, alsohttp://wiki.squeak.org/squeak/2106
VMMaker is not kept in the main image; it’s irrelevant to almost everyone and would be a waste of space. Use Monticello and try following http://wiki.squeak.org/squeak/6177 to start off.
(Note to Dave - your swiki page - http://wiki.squeak.org/squeak/6177 - is a tad out of date though mostly ok.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.)
a few questions:
- Which version of vmmaker i have to use to build the vm of rapsberry?
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.
- Has vmmaker dependencies?
Only as handled in the ‘update’ configuration; that handles all of it.
- how to load ?
Described on http://wiki.squeak.org/squeak/6177 as above
- which is the order ?
n/a
- which versions ?
n/a
