[Pharo-project] problems trying to run headless

by sergio_101

i have upgraded my squeak VM to: 4.0.3-2202 after having problems getting it to run on: 3.11.3.2135 Unix VM but i am still having problems getting my headless to run.. 'run' looks like this: # settings USER="optimizeguys" VM="/usr/local/bin/squeak" VM_PARAMS="-mmap 256m -vm-sound-null -vm-display-null" IMAGE="Pier.image" # start the vm exec \ /usr/local/bin/setuidgid "$USER" \ "$VM" $VM_PARAMS "$IMAGE" the error i am getting is: # ./run SQUEAK_ENCODING=UTF-8 SQUEAK_PATHENC=UTF-8 SQUEAK_PLUGINS=/usr/local/lib/squeak/4.0.3-2202 + exec /usr/local/lib/squeak/4.0.3-2202/squeakvm -mmap 256m -vm-sound-null -vm-display-null Pier.image This interpreter (vers. 6502) cannot read image file (vers. 6505). Press CR to quit... any ideas? thanks! -- ---- peace, sergio photographer, journalist, visionary http://www.CodingForHire.com http://www.coffee-black.com http://www.painlessfrugality.com http://www.twitter.com/sergio_101 http://www.facebook.com/sergio101

[Pharo-project] Trying SimpleMorph crashes

by Robert Hawley

I have installed SimpleMorphic from a file browser into Pharo1.2a @12241 but when I try something like: x := SMxStarMorph new openInHand the system hangs with a eventual crash-out saying: ***System error handling failed*** Original error: Error: MessageNotUnderstood: SMxStarMorph>>ownerChanged. Debugger error: MessageNotUnderstood: SMxStarMorph>>wantsToBeCachedByHand: MorphicUIManager>>onPrimitiveError: ...... etc. There are similar problems when trying this in the one-click Pharo image.

Swapping in a real method may invoke methods that weren't used during the simulation. For example my implementation uses #storeString to serialize the methods and Compiler >> #evaluate: to deserialize them. So during deserialization a lot of different methods may be invoked. Levente

[Pharo-project] Issue 3277 in pharo: [FIX] Replace #& in Socket with #and: to save #isConnected send

by pharo＠googlecode.com

Status: Accepted Owner: philippe.marschall Labels: Difficulty-Easy Importance-Low Type-RequestForEnhancement Milestone-1.2 New issue 3277 by philippe.marschall: [FIX] Replace #& in Socket with #and: to save #isConnected send http://code.google.com/p/pharo/issues/detail?id=3277 Socket #waitForSendDoneFor: and #waitForSendDoneUntil: use #&. We can replace this with #and: to save #isConnected self send in case #primSocketSendDone: answers true. This is likely the case in local host due to shared memory (eg. Seaside behind an Apache). In order to preserve the exact same semantics we have to swap the receiver and argument of #&. I'll a commit a patch shortly but I first need to have an id so that I can reference it.

I do not think that we can build something on simpleMorphic, what we can do is look at the kernel and see how the changes can be applied to Morphic. But may be I'm wrong. Tell me what you think. What is clear is that I would like to have the Sophie evtn hierarchy because we will start cleaning event soon internally. Stef

Re: [Pharo-project] [ANN] DrGeo release 10.12

by Hilaire Fernandes

Thanks Laurent. I have just upload a few more screencasts on that Advanced Tools (http://community.ofset.org/index.php/Screencast_DrGeo#Advanced_tools) I can suggest a look at this one: http://people.ofset.org/hilaire/drgeo2/tutorials/AdvancedTools/904-smalltal… It features Smalltalk scripting in a geometric sketch to extend the software in unexpected (of course) direction. This is really the heart of DrGeo, even if not very visible. Hilaire Le 20/11/2010 21:03, laurent laffont a Ã©crit : > I've just watched the screencasts, it's a very cool 'real world' > application.
