SegmentationFault in with OmniBrowser
by Damien Cassou 24 May '07

24 May '07

Hi, you will find here http://damien.cassou.free.fr/crashing.zip an image which makes the VM segfault. To reproduce: - Open the image - Open an 'image browser' from the world menu->open... - Choose a class and click on one of the 3 filters 'instance' '?' or 'class'. The VM say: Segmentation fault 2032029316 [] in OBMetaNode>childrenForNode: 2032030488 [] in Collection>gather: 2032030004 OrderedCollection>do: 2032029408 [] in Collection>gather: 2032029500 >streamContents: 2032029224 Collection>gather: 2032028672 OBMetaNode>childrenForNode: 2032028580 OBNode>childNodes 2032028488 OBColumn>getChildren 2032027384 OBColumn>basicParent: 2032027108 OBColumn>parent: 2032027200 [] in OBColumnPanel>selected: 2032026924 Object>ifNotNilDo: 2032025812 OBColumnPanel>selected: 2032025720 OBColumnPanel>selectionChanged: The problem is that I can easily reproduce the crash. Just take a squeak-dev-beta-123 from http://damien.cassou.free.fr/squeak-dev/beta/, and use the 'Package Universe Browser' to upgrade to latest OB ('update list from network', 'select all upgrades' 'install selection'). Can somebody help me? -- Damien Cassou

SqueakVM help for OLPC
by Chris Petsos 24 May '07

24 May '07

Hi all! This is Christos Petsos... i am actively participating in localising OLPC in greek language... I am involved in localising eToys in Greek right now...i'll try to be brief on what i am searching... We are trying to make Squeak work with Unicode...Yoshiki Ohshima has been very helpful till now and his suggestion was to let all the data that the platform (e.g. Windows, Unix etc...) is sending, enter the Squeak VM as is and deal with them there (in the image side) with InputInterpreter classes. I am a bit familiar with VMMaker ( just today i downloaded it and managed to compile a VM for my Windows platform) and now i want to find the place where the VM filters keycodes above 255. Another clue is that Squeak in Windows uses ANSI versions of Windows functions which support only 8-bit characters, such as CreateDirectoryA CreateEventA CreateFileA CreateMutexA CreateProcessA DeleteFileA Any idea on how we can work this out so that Squeak can use the Unicode equivelant functions so that it can support Wide Characters ... CreateFileW lstrcmpiW GetCommandLineW lstrcatW FindFirstFileW GetFileAttributesW lstrcmpW lstrcpynW FormatMessageW DeleteFileW GetTextExtentPoint32W ? Or even just tell the VM to let all the bits enter the image and deal with them there? Your help will speed us up a lot so any ideas are most welcome! Thank you in advance... Christos

I think the "BackSpace" keystroke was problematic because i had some output to the Transcript (the evtBuf Array). Since i commented out the " Transcript show: evtBuf asString; cr." line. i cannot reproduce the problem in any way... Christos.

At the very least it would be appropriate to have the new Midi plugin available for the masses. I'm suggesting to make this plugin available when people download the standard Linux VM. As it is, msgs are sent out by users complaining that Midi doesn't work. Why? If I'm not mistaken, the midi plugin that is currently distributed is the old one that contains stubs. The one Cesare built is the one from the OLPC branch. Please correct me if I'm wrong. brad -- brad fuller website: www.bradfuller.com linkedin: http://www.linkedin.com/in/bradfuller +1 (408) 799-6124

Building VM on 64-bit machines
by Mandeep Gill 21 May '07

21 May '07

Hi, I am trying to build the Squeak VM on 64-bit linux with gcc 4.1 but am having problems with both compiling the sources and running images. I'm found some information on www.squeakvm.org/squeak64, however I'm not sure how up to date it is. I've downloaded the latest sources from the squeak-vm subversion repository and have tried building it using several different compile options. Trying to compile as per the standard instructions succeeds, but I am not sure what if it compiles a 32 or 64 bit VM. Regardless this VM crashes using the standard Squeak3.9-final-7067 image with a segmentation fault. "16256940 SmalltalkImage>snapshot:andQuit:embedded: 16256824 SmalltalkImage>snapshot:andQuit: 16256396 SmalltalkImage>saveImageInFileNamed: ... 16243080 PasteUpMorph>doOneCycle 15589312 [] in >spawnNewProcess 15589496 [] in BlockContext>newProcess Aborted (core dumped)" I found a 64-bit image sq64-10-dtl.image on http://www.barnet.sk/software/squeak however the VM will not load this either, giving the error "This interpreter (vers. 6502) cannot read image file (vers. 68000). Press CR to quit..." If I run configure with the options "with-src=src64" or "with-src=src32" (as I have 32bit compatibility libraries installed) the compile exits with "gcc -g -O2 -DLSB_FIRST=1 -o squeak disabledPlugins.o version.o -Wl,--export-dynamic vm/vm.a B2DPlugin/B2DPlugin.a BitBltPlugin/BitBltPlugin.a FilePlugin/FilePlugin.a SocketPlugin/SocketPlugin.a -lutil -ldl -lm -lnsl vm/vm.a -Wl,--rpath -Wl,/usr/local/lib vm/vm.a(sqVirtualMachine.o): In function `sqGetInterpreterProxy': /home/mandeep/dev/tmp/squeak/squeak-svn/platforms/Cross/vm/sqVirtualMachine.c:202: undefined reference to `obsoleteDontUseThisFetchWordofObject' /home/mandeep/dev/tmp/squeak/squeak-svn/platforms/Cross/vm/sqVirtualMachine.c:333: undefined reference to `fetchLong32ofObject' /home/mandeep/dev/tmp/squeak/squeak-svn/platforms/Cross/vm/sqVirtualMachine.c:334: undefined reference to `getThisSessionID' /home/mandeep/dev/tmp/squeak/squeak-svn/platforms/Cross/vm/sqVirtualMachine.c:335: undefined reference to `ioFilenamefromStringofLengthresolveAliases' /home/mandeep/dev/tmp/squeak/squeak-svn/platforms/Cross/vm/sqVirtualMachine.c:336: undefined reference to `vmEndianness' collect2: ld returned 1 exit status" Is anyone running Squeak currently on a 64bit system - what needs to be done to get a basic VM and image (32 or 64 bit) working? Many Thanks, Mandeep

Can we move this code into the main so that it will be available? What do we need to do to make this available for all? I guess this is a question for Ian.

Ok... this is the point i am now... in file sqWin32Window.c there is... /* The following is a mapping to Mac Roman glyphs.

(Did i mention that i am trying to make it work in a Windows system?...well i am...) What can i do to retrieve Unicode charcodes? Christos

Regarding TestOSAPlugin & Applescript
by Ken G. Brown 07 May '07

07 May '07

I did some digging into TestOSAPlugin. It looks to me that some late AppleScript support is available from SqueakMap as Applscript, and that the latest changeset is here: <http://www.squeaksource.com/Applescript.html> <http://www.squeaksource.com/Applescript> Andrew Greenberg is the original author. Javier Díaz Reinoso is the name on the Squeaksource project. I have not yet located the TestOSAPlugin source code. Anyone have it? See emails from archives far below. And it might be a good idea to perhaps take TestOSAPlugin out of the picture in VMMaker since Applescript is a better name. This may have impact on 'AppleScript Media Player Interface' on SqueakMap which appears to require TestOSAPlugin, as does the Applescript changeset on SqueakMap. . Javier Díaz Reinoso said on Nov 2 2005, >I put an update for Applescript that works in 3.8 in squeaksource: > >> http://kilana.unibe.ch:8888/Applescript.html > >this version is not full compatible with the unicode changes in 3.8 >or AppleScript 1.10 for Mac OS X 10.4, for that further changes are >needed, also a new plugin. > >Be aware that scripts who use the line continuation character 0xC2 >(194) can have problems in 3.8, that is because reading the file >convert this character to 0xAC (macToSqueak).

What is the theoretical difference between the SDKs, as far as Squeak is concerned ? I fiddled with that and I can't exactly remember what I finally put in there. After the case issues (e.g. IOKit/HID/IOHIDLib.h should have been IOKit/hid/IOHIDLib.h), I had to comment out a couple of mentions to exupery somewhere, and the VM built.
