Hi Sven and others,

I've attached a screen shot of Pharo 20623.image running on the Raspberry
Pi - I'd connected through a VNC session into my Mac. The image is almost
unusably slow - I don't know if the problem lays in the graphical
performance + VNC rather than the bytecode execution. tinyBenchmarks give:

0 tinyBenchmarks '10471204 bytecodes/sec; 307552 sends/sec'

I came across a "PrimitiveFailed" walk-back from NativeBoost
class>>#isEnabled and just commented out the primitive call and instead
returned false. I guess this is probably as the VM sources I have date back
to April/May so probably aren't completely compatible with 2.0.

I've shared my Raspberry Pi build folder "result" on dropbox, which
contains the StackVM executable built on the Pi:
https://www.dropbox.com/sh/cnta1hjoo7ptv1j/CELvuMjIRl

I haven't tried installing the built StackVM onto a clean Pi distribution
so don't know if any of the packages I installed during the build process
will also be required for executing the StackVM - don't complain too loudly
if just copying the contents from dropbox doesn't work directly on your Pi.

I found some more notes I made while trying to compile the VM - though
reading them back they seem more like the ramblings of a mad man and I'm
sure the problems I ran into compiling the StackVM will be sorted by now:
https://docs.google.com/document/d/1ZIzvTmV4zkYrFgOdAzfZzC35iMAqI2jc-44XQO9wSwc/edit?usp=sharing

Also note that Pharo1.2.1 works with the VM used for Scratch in the
Raspberry Pi distribution - without the need to build your own VM.

Sorry I don't have many free cycles to support, but hope this might help
someone to create a "blessed" Raspberry Pi Pharo VM

Cheers

Nick

Hi,

I managed to compile a StackVM on the raspberry Pi - a couple of months
      

ago - though I haven't tried with the latest StackVM source. I meant to
write it up, but life got in the way I'm afraid.

What you did (and I can't) is indeed what should be done: recompile
locally ;-)

So the conclusion is that it worked and that you can now run Pharo 2.0
(and presumable 3.0) as well ?

That would be excellent and important news !  And the best short term
solution.

Either you (but you lack time) or somebody else who feels at home with
this stuff should redo your steps and produce the actual VM, so that us
weak high-level programmers can have our Pharo and play ;-)

Thanks,

Sven

    

The procedure I took was:
* From a PC running Pharo install VMMaker packages (I found it was
      

easiest to run under a Linux (eg Ubuntu) to match the PIs OS.
    

* Export the StackVM source
* Install the build tools on the raspberry Pi
* Copy exported StackVM source (need to ensure it is copied to exactly
      

the same place, eg /home/nick/build)
    

* Build and test with Pharo2.0.image

I choose to build on the Raspberry Pi as in my experience setting up a
      

reliable cross-compiling environment can take days.
    

Here are some notes I made at the time:

On the raspberry PI:
# install build tools
sudo apt-get install gcc g++ cmake

# dependencies for vm plugins
sudo apt-get install libasound2-dev libssl-dev libfreetype6-dev
      

libgl1-mesa-dev
    

sudo apt-get install build-essential

# to fix:
# /usr/bin/ld: cannot find -lSM
#/usr/bin/ld: cannot find -lICE
# create the following links in: /usr/lib/arm-linux-gnueabihf/

sudo ln -s libSM.so.6 libSM.so
sudo ln -s libICE.so.6 libICE.so

Once the source is installed:

chmod +x platforms/unix/config/version
chmod +x platforms/unix/config/verstamp

At the time I had to patch a couple of files, but that might have
      

changed with later versions of the StackVM source. My notes say I modified
the following, though don't indicate what I changed:
    

platforms/Cross/vm/sqAtomicOps.h
platforms/unix/vm/sqUnixITimerHeartbeat.c
platforms/unix/vm/vmVersionInfo.h
src/vm/gcc3x-interp.c


Hope this helps

Nick

Hi all,

I'm trying to know if it is possible to run a version of pharo, recent
      

if possible, on the Raspberry Pi?
    

I know that there is a squeak vm on Raspian (Debian for the RaspberryPi)
      

but it doesn't load recent pharo images.
    

Using the VM that comes with Raspbian, you can run Pharo 1.4.
Pharo 2.0 requires additional VM support.

Sven

Thanks,

Thierry
