I just did this (twice, just to make sure) in the 7058 imagine and squeak bombed with the output below. This was with the latest Linux 3.9 VM. I tried with the 3.7-7 VM and it bombed too. kernel: 2.6.16-1.2080.16.rrt.rhfc5.ccrma (realtime kernel from Stanford - for audio)
what's the problem? (Note Andreas said to Avi in a Sep12 msg regarding similar error: "I think you're seeing the old problem of signed vs. unsigned ints when accessing memory locations (the negative numbers seem to indicate that much). Try a later VM (3.9-7 is the latest according to SqueakVM.org) - IIRC, then this problem got fixed in later versions. ) Just to show I'm using the 3.9 version: [EMAIL PROTECTED] images]$ which squeak /usr/local/bin/squeak [EMAIL PROTECTED] images]$ ls -lsa /usr/local/bin/squeak 0 lrwxrwxrwx 1 bfuller sonaural 26 Sep 14 16:56 /usr/local/bin/squeak -> ../lib/squeak/3.9-7/squeak [EMAIL PROTECTED] images]$ ls /usr/local/lib/squeak/3.9-7 AioPlugin Squeak3D vm-display-X11 B3DAcceleratorPlugin UnixOSProcessPlugin vm-sound-null npsqueak.so UUIDPlugin vm-sound-OSS PseudoTTYPlugin vm-display-fbdev XDisplayControlPlugin squeak vm-display-null ------------------------------------------------------ sweep failed to find exact end of memory -2128024296 Point>+ -2128024388 Rectangle>center -2128026592 Morph>layoutInBounds: -2128027312 Morph>layoutProportionallyIn: -2128046872 [] in ProportionalLayout>layout:in: -2128046964 SequenceableCollection>do: -2128047056 Morph>submorphsDo: -2128047148 ProportionalLayout>layout:in: -2128054100 Morph>doLayoutIn: -2128055204 [] in Morph>fullBounds -2128055020 BlockContext>on:do: -2128055388 Morph>fullBounds -2128055296 [] in Morph>submorphBounds -2128055480 SequenceableCollection>do: -2128055572 Morph>submorphBounds -2128057332 Morph>privateFullBounds -2128065988 Morph>doLayoutIn: -2128067000 [] in Morph>fullBounds -2128066816 BlockContext>on:do: -2128067092 Morph>fullBounds -2128067184 MorphicEventDispatcher>dispatchDefault:with: -2128067276 MorphicEventDispatcher>dispatchEvent:with: -2128067384 Morph>processEvent:using: -2128067812 PasteUpMorph>processEvent:using: -2128067960 Morph>processEvent: -2128068052 HandMorph>sendEvent:focus:clear: -2128068296 HandMorph>sendMouseEvent: -2128068388 HandMorph>handleEvent: -2128068768 MouseOverHandler>processMouseOver: 2032428416 HandMorph>handleEvent: 2032428116 HandMorph>processEvents 2032428208 [] in WorldState>doOneCycleNowFor: 2032428024 SequenceableCollection>do: 2032427932 WorldState>handsDo: 2032427840 WorldState>doOneCycleNowFor: 2032427748 WorldState>doOneCycleFor: 2032427656 WorldState>doOneSubCycleFor: 2032427564 PasteUpMorph>doOneSubCycle 2032409876 MenuMorph>invokeModalAt:in:allowKeyboard: 2032409784 MenuMorph>invokeModal: 2032409416 MenuMorph>invokeModal 2032402804 PluggableTextMorph>yellowButtonActivity: 2032402712 TextMorphForEditView>mouseDown: 2032402620 Morph>handleMouseDown: 2032402528 MouseButtonEvent>sentTo: 2032402436 Morph>handleEvent: 2032402332 MorphicEventDispatcher>dispatchMouseDown:with: 2032402200 MorphicEventDispatcher>dispatchEvent:with: 2032402108 Morph>processEvent:using: 2032401976 MorphicEventDispatcher>dispatchMouseDown:with: 2032401844 MorphicEventDispatcher>dispatchEvent:with: 2032401752 Morph>processEvent:using: 2032401660 MorphicEventDispatcher>dispatchMouseDown:with: 2032401568 MorphicEventDispatcher>dispatchEvent:with: 2032401476 Morph>processEvent:using: 2032401344 MorphicEventDispatcher>dispatchMouseDown:with: 2032401252 MorphicEventDispatcher>dispatchEvent:with: 2032401160 Morph>processEvent:using: 2032401068 MorphicEventDispatcher>dispatchMouseDown:with: 2032400976 MorphicEventDispatcher>dispatchEvent:with: 2032400868 Morph>processEvent:using: 2032400776 PasteUpMorph>processEvent:using: 2032400592 Morph>processEvent: 2032400500 HandMorph>sendEvent:focus:clear: 2032400408 HandMorph>sendMouseEvent: 2032400264 HandMorph>handleEvent: 2032400044 HandMorph>processEvents 2032400136 [] in WorldState>doOneCycleNowFor: 2032399952 SequenceableCollection>do: 2032399860 WorldState>handsDo: 2032399768 WorldState>doOneCycleNowFor: 2032399676 WorldState>doOneCycleFor: 2032399584 PasteUpMorph>doOneCycle 2025718576 [] in >spawnNewProcess 2025718760 [] in BlockContext>newProcess _______________________________________________ Beginners mailing list Beginners@lists.squeakfoundation.org http://lists.squeakfoundation.org/mailman/listinfo/beginners
