Re: [Pharo-dev] Pharo for the Raspberry Pi

by Nick Ager

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-44XQO9… 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 On 2 October 2013 12:47, Sven Van Caekenberghe <sven(a)stfx.eu> wrote: > Hi Nick, > > On 02 Oct 2013, at 11:51, Nick Ager <nick.ager(a)gmail.com> wrote: > > > 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.

Re: [Pharo-dev] SmalltalkHub red

Yes, running the Grease/Seaside tests works fine. But, you will only see the "packages" problems when you do something with packages. So you will have to trigger RPackage tests to notice the issue. After all, you spotted the issue by running the Pharo regression tests after loading Moose/Grease/Seaside.
