Here is what I did (on a fresh Raspberry Pi 2 B) $ uname -a Linux raspberrypi 4.1.13-v7+ #826 SMP PREEMPT Fri Nov 13 20:19:03 GMT 2015 armv7l GNU/Linux
$ curl get.pharo.org/50 | bash $ wget http://files.pharo.org/sources/PharoV40.sources.zip $ wget http://files.pharo.org/vm/pharoS/raspbian/latest.zip Both the PharoS and squeak VM that comes with Raspbian 7 fail (not Spur compatible): $ squeak -nodisplay Pharo.image printVersion found gettext in path /home/pi/Pharo This interpreter (vers. 0) cannot read image file (vers. 6521). Press CR to quit... pi@raspberrypi ~/Pharo $ ./pharosvm/PharoS -nodisplay Pharo.image printVersion unknown option: -nodisplay $ ./pharosvm/PharoS --nodisplay Pharo.image printVersion This interpreter (vers. 6505) cannot read image file (vers. 6521). Press CR to quit... The Cog VM does work: $ ./cogspurlinuxhtARM/lib/squeak/5.0-3427/squeak -nodisplay Pharo.image printVersion [version] 5.0 #50581 It is way faster than PharoS on an older B+. But it does have an annoying slowdown in shutting down: it starts up OK, executes its eval expression immediately, but then seems to wait a couple of seconds before shutting down: pi@raspberrypi ~/Pharo $ echo `date`; time ./cogspurlinuxhtARM/lib/squeak/5.0-3427/squeak -nodisplay Pharo.image eval 'DateAndTime now'; echo `date` Sat Feb 13 15:45:44 UTC 2016 2016-02-13T15:45:44.860574+00:00 real 0m7.415s user 0m7.210s sys 0m0.250s Sat Feb 13 15:45:51 UTC 2016 This takes 7 seconds, while the DateAndTime now is printed just .86 seconds after starting. Running an HTTP server worked fine. I will try to get my actual app running and then test OS(Sub)Process. Sven PS: it is a bit odd that the latest Cog VM was published in August, nothing new since then. > On 13 Feb 2016, at 09:46, Clément Bera <bera.clem...@gmail.com> wrote: > > Hello Sven, > > You can use the VM with the JIT on the Pie now (Spur Cog VM).
