So the glue in platforms/Cross/plugins/IA32ABI/dabusiness.h needs rewriting. Specifically the second loop over the arguments at line 45 needs to mimic the code at line 17.

I have Alien callbacks integrated with the FFI and of course the ALien data manipulation code works fine. So if you're eager to have Alien callouts work see whether the above change fixes things, in which case I can integrate the fix. But if you're not so eager you could wait for me to push out the FFI changes, but that could take a few weeks. > > HTH > Eliot > > -- > Ken Treis > Miriam Technologies, Inc. > > >

Re: [Pharo-project] Z3950 on OSX: module yaz3 not found

by HernÃ¡n Morales Durand

Laurent, not much progress here :( I just reproduced the Unix VM crash. First I've linked the library so we do not have to change every module name call user@ubuntu:/usr/lib$ ln -T -s /usr/lib/libyaz.so.3.0.0 yaz and I've tried to execute the library tracer in the shell script ltrace -f -l /usr/lib/libyaz.so.3.0.0 -o out.txt "$BASE/squeakvm" \ -plugins "$BASE" \ -encoding latin1 \ -vm-display-X11 \ "$ROOT/Contents/Resources/pharo.image" but it crash the VM too with an unhandled exception even before the GUI is displayed. What I've observed is that every FFI call which receives an ExternalStructure as parameter kills the VM. This is weird because this doesn't happen in the Windows VM. I ran this little script I use to debug the library | conn lib rs rsSize records | lib := Z3950FFILibrary default. conn := lib createConnectionTo: #Alabama asZ3950Server hostName port: 7090. lib createOptions. lib setConnection: conn optionName: 'preferredRecordSyntax' optionValue: 'USMARC'. rs := lib searchPqf: conn query: '@attr 1=1003 collins'. rsSize := lib resultSetSize: rs. rsSize > 0 ifFalse: [ 'no results' ]. records := Array new: rsSize. 0 to: rsSize - 1 do: [: pos | record := lib resultSetRecord: rs position: pos. record isNil not ifTrue: [ records at: pos + 1 put: ( lib getRecord: record function: 'render; charset=marc8, iso8859-1' length: nil ). ] ]. records and the the doIt just hangs the VM, the console output going through the Debugger is the following: Segmentation fault -1370902312 ContextPart>doPrimitive:method:receiver:args: -1370902404 ContextPart>tryPrimitiveFor:receiver:args: -1370902788 ContextPart>send:to:with:super: -1370902896 ContextPart>send:super:numArgs: -1370902988 InstructionStream>interpretExtension:in:for: -1370903080 InstructionStream>interpretNextInstructionFor: -1370903172 ContextPart>step -1370903280 Process>step -1370903372 Process>step: -1370920392 Debugger>send -1370937720 PluggableButtonMorph>performAction -1370937812 PluggableButtonMorph>mouseUp: -1370937996 SequenceableCollection>do: -1370957140 PluggableButtonMorph>mouseUp: -1370957232 Morph>handleMouseUp: -1370957324 MouseButtonEvent>sentTo: -1370957416 Morph>handleEvent: -1370957584 Morph>handleFocusEvent: -1370957676 HandMorph>sendFocusEvent:to:clear: -1370957768 PasteUpMorph>becomeActiveDuring: -1370957860 BlockClosure>on:do: -1370957992 PasteUpMorph>becomeActiveDuring: -1370958084 HandMorph>sendFocusEvent:to:clear: -1370958260 HandMorph>sendEvent:focus:clear: -1370958352 HandMorph>sendMouseEvent: -1370958444 HandMorph>handleEvent: -1370966728 HandMorph>processEvents -1370966836 WorldState>doOneCycleNowFor: -1370966952 SequenceableCollection>do: -1370967044 WorldState>handsDo: -1370967136 WorldState>doOneCycleNowFor: -1370969680 WorldState>doOneCycleFor: -1370969772 PasteUpMorph>doOneCycle -1383611064 >spawnNewProcess -1383611192 BlockClosure>newProcess Aborted it would be nice if someone could tell something about debugging FFI calls, or just any idea to try.
