I am making progress.

It seems 1.4 does run out of the box, at least headless:

pi@raspberrypi ~/Pharo-1.4 $ cat test.st

FileStream stdout
� nextPutAll: 'Hello World, 42 factorial = '; print: 42 factorial;
� crlf; flush.

Smalltalk quitPrimitive.

pi@raspberrypi ~/Pharo-1.4 $ /usr/lib/squeak/4.4.7-2357/squeakvm -vm-display-null -vm-sound-null /home/pi/Pharo-1.4/Pharo-1.4.image /home/pi/Pharo-1.4/test.st

Hello World, 42 factorial = 1405006117752879898543142606244511569936384000000000

No HTTP server like apache is installed by default, lucky Zn comes with Pharo then ;-)

pi@raspberrypi ~/Pharo-1.4 $ cat zn.st

ZnServer startDefaultOn: 1701.

pi@raspberrypi ~/Pharo-1.4 $ /usr/lib/squeak/4.4.7-2357/squeakvm -vm-display-null -vm-sound-null /home/pi/Pharo-1.4/Pharo-1.4.image /home/pi/Pharo-1.4/zn.st

And now visit http://localhost:1701 or (with avahi-daemon installed) http://raspberrypi.local:1701 from another machine, at first sight everything seems to work as expected. Things are a bit slow with the slower ARM CPU and a Stack VM, but that is normal.

As for 2.0, there seems to be some startup problem:

Some code is referring to the VM directory and that seems to fail. Funny there is no better/usable stacktrace.

I wonder whether FileSystem is completely supported on older VMs ?
