And it's even running Squeak now, albeit only v3.8; something I changed for 3.9 in the vm makes it go very funny… even though that used to work just fine on Ye Olde Iyonix. I expect it will be something stupidly silly when I find it.

Hi Tim,

Just guessing, but have a look at CCodeGenerator>>emitDefaultMacrosOn:
and the resulting macros in src/vm/interp.c. There are some macros that
I added in a attempt to keep some back compatibility with platforms sources
as new things were added in the interpreter. Some of these macros turned
out to be a Really Bad Idea, in particular I recall the macros for clock
functions made it look like the VM compiled without problems, but the
resulting VM did not work properly.

So far so good; some weird buglets in the particular version of the OS but Squeak is working reasonably well.

Host window code still works, too.

OK, RISC OS Pi squeak is now available as a tentative demo pre-alpha possibly useful maybe release at http://www.rowledge.org/tim/squeak/Squeak3-9-RISCOS.zip 
If you try it and like it, remember to mentally thank Chris Cunnington for providing the dev-tools and the Pi Foundation for providing the tasty Pi. And offer up wishes for somebody realising that they need to *pay me* to develop stuff.

Apparently Scratch runs on it, though I haven't tried and wouldn't really have any current experience to judge it by.

Life would be much easier if I had the source code.

Hi Tim,

Very cool, and nice to see Squeak running again on STINU (*). I have to ask - were
you able to do this with an up to date VMMaker with closures etc? I confess that
I was a bit worried that the various changes to VMMaker since the last RISC OS
release would cause a real mess. Hopefully it was not too bad?

I do think that it would be a sad injustice if the RISC OS community was deprived
of the ability to run 64-bit Squeak images on Raspberry Pi. So I think you
should try compiling with -D SQ_VI_BYTES_PER_WORD=8 and see if the resulting
vm can run a 64-bit image like the one here:

OK, this first go is a 3.9-ish VM for running up to a 4.0 image. Let's walk before we try to unicycle whilst juggling fusion powered chainsaws while blindfolded.

64 bit doesn't make any real sense on an ARMv7 or below cpu; let's wait for the upcoming ARMv8 cpus which will eat intel alive.

All the simple programs have been written, and all the good names taken.
