Porting spoon's VM support

[Tony Garnock-Jones-2]

Hi all,

I've just finished getting Squeak running on the Neo1973 [1], an
OpenMoko [2] open-source GSM cellphone. So far, I have the stock VM able
to run stock images. In order to develop for the phone, I'd like to try
out a spoonish approach, so I thought I'd try to get spoon running.

I'm having trouble in two areas: cross-compiling an appropriate Flow
plugin (I need the latest primitive sources) and building an appropriate VM.

Could someone confirm for me that I will *not* be able to use a stock
Unix Squeak VM, say 3.9-8, with Spoon and an appropriate Flow plugin?
That is, are there mandatory changes to the core VM that need to be applied?

Thank you,
   Tony

WOW!

Tony, do you have a smalltalk API built around the hardware on that
platform?  For instance the GPS device, etc?  So that squeak apps can
be built to interface with the hardware?

I'm more of a lurker on this list, but that's a very interesting
project.  Where do you normally post about your progress?

Cheers,
Mike

I'm building one. The kernel programmers have done a smooth job of the
interface between the kernel and the userland. For instance, the
touchscreen is available by reading /dev/input/event2, and the GSM chip
is available through a few control files in /sys/ and by writing
Hayes-style AT commands to /dev/ttySAC0.

So far, just one post to LShift's blog:

      That's right, you need to apply "spoonProcessorChanges.st" before
generating interp.c, to get remote messaging support. Also, Squeak seems
to have trouble on some Linux hosts with loading the released Flow
shared library, due to differences in the pthreads shared library
location. I'd be happy to help you with this.


      thanks,

-C

Thanks, Craig!

I've managed to get a Flow plugin building and running now (hooray!) so
the remaining thing for me to pin down the details of is the interp.c
regeneration process.

I'll take a stab at that this evening or tomorrow.

Regards,
  Tony
