I tried the ARM VMs published at http://www.mirandabanda.org but they failed, even on a standard RaspberryPi running Rasbian (wrong libc) - these seem to be compiled statically for a too specific range of machines/OSes. But then I tried the JB ones and they worked fine ! I used this link: https://ci.inria.fr/pharo-contribution/job/RaspberryPi-Cross-Compilation-JB/... After adding PharoV30.sources I got Pharo 3 running on the command line including a normally functioning Zn HTTP server. On the Online Labs machines I had to install libasound2 as well. The Online Labs machines seem pretty fast: ubuntu@c1-10-1-14-179:~$ ./jb-vm/PharoS -vm-display-null Pharo.image eval '1 tinyBenchmarks' '39975015 bytecodes/sec; 2174908 sends/sec' vs a Raspberry Pi: pi@raspberrypi ~/pharo $ ./jb-vm/PharoS -vm-display-null Pharo.image eval '1 tinyBenchmarks' '13377926 bytecodes/sec; 719200 sends/sec' That looks like a factor 3 to 4 faster. But it is way slower than the regular VM on my machine: prometheus:pharo4 sven$ ./pharo Pharo.image eval '1 tinyBenchmarks' '985563041 bytecodes/sec; 160902758 sends/sec' Probably the plain stack VM vs the Cog JIT is a factor too. Thanks JB ! Is this VM production ready (so to speak) ? Sven PS: We still need easier access to this + better instructions.

Hi Sven,

I just saw this: http://labs.online.net which offers real ARM cloud servers (15 minutes for free to try out) [they're French]. This is Ubuntu 14.10 on ARMv7.
Naturally I wanted to try Pharo on such a machine.
The base question is, where do I get the latest and best VM to try this ?
Doug McPherson is building Stack VMs for ARMv6 and ARMv7 for both Cog and Spur and uploading them to my site. These VMs should run Pharo. See e.g. http://www.mirandabanda.org/files/Cog/VM/VM.r3126/
I tried that and it does not seem to work:
ubuntu@c1-10-1-16-102:~$ ls Pharo.changes Pharo.image PharoV30.sources stklinuxhtARM stklinuxhtARMv7-14.45.3126.tgz
ubuntu@c1-10-1-16-102:~$ ./stklinuxhtARM/bin/squeak -vm-display-null Pharo.image printVersion pthread_setschedparam failed: Operation not permitted Read e.g. http://www.mirandabanda.org/files/Cog/VM/VM.r3126/README.3126
Maybe their system is special, I don't know, it feels pretty standard, running the latest Ubuntu.
I noticed the 'ht' in the VM name, is there no 'normal' one ?
I will try on a Raspberry Pi as well.
Maybe a complete & easy to use source tree that can be compiled locally ?
That's the case for http://www.squeakvm.org/svn/squeak/branches/Cog. See http://www.squeakvm.org/svn/squeak/branches/Cog/build.linux32ARM
And would it make sense to add some ARM option to get.pharo.org ?
Thx,
Sven
