Smalltalk metacelloPlatformAttributes #(#squeakCommon #pharo #'pharo2.x' #'pharo2.0.x') I have the impression that we should better have #(#squeakCommon #pharo #'pharo2.0' #'pharo2.0.x') what do you think? Stef

[Pharo-project] [UPD] New VMs available.
by Igor Stasenko Oct. 26, 2012

Oct. 26, 2012

Hi there, There are new updated Cog VMs built by Jenkins. The changes are mostly related to Windows builds: [1] Cog VM includes SSL plugin which uses OpenSSL library. (Tested versus Zodiac , seems working fine). [2] A new version of Cog+NativeBoost for windows also bundled with Cairo library. Here the list of all extra dll's which you can find in .zip file: "freetype library + freetype plugin" FT2Plugin.dll libfreetype-6.dll "FFI" SqueakFFIPrims.dll "openSSL library + SqueakSSL plugin" SqueakSSL.dll libeay32.dll ssleay32.dll "cairo library and its dependencies" libcairo-2.dll libpixman-1-0.dll libpng-3.dll zlib1.dll Please, also note new downloads location: [1] http://pharo.gforge.inria.fr/ci/vm/cog/ [2] http://pharo.gforge.inria.fr/ci/vm/nbcog/ While you can still download VMs directly from jenkins server (https://ci.lille.inria.fr/pharo/view/Cog/) the new location is _recommended_ place for downloading artefacts built by Jenkins server: - first, the interface is simple and straightforward - second, it is not going to disappear with a puff of smoke (in case of any problems related to jenkins & other build infrastructure) The new artifacts will appear in archive, every time jenkins successfully finish corresponding job(s). You can look at (http://pharo.gforge.inria.fr/ci/) to see what else is stored there. -- Best regards, Igor Stasenko.

[Pharo-project] NativeBoost FFI
by Ciprian Teodorov Oct. 26, 2012

Oct. 26, 2012

Hi guys, Over the weekend I had a look at NativeBoost FFI and I have enjoyed it. I really like this idea of taming the beast from high-level languages. However I ran into some problems with the number of arguments one can pass to a smaltalk method (it turns out to be 15 at max)... That bad for FFI especially when you want to interface with legacy c code without touching the C-stuff (header, object files, etc). In consequence I've hacked my way around this limitation by introduction of a new type of arguments that we can pass to callouts. I call these arguments "in object arguments". The idea isn't new and is very simple, instead of passing 20 arguments to your function just pass one an array with all the arguments you need. Where it turns interesting is that I think we can pass more than just an array we can pass real objects (think about ParameterObject) that hold in their instance variables the arguments we want. lets say that we want to call a function " int function(int x, int y)", now with the NativeBoost wrapper we will get a call something like function_x: x y: y <primitive: #primitiveNativeCall module: #NativeBoostPlugin> ^ self call: #( int function (int x, int y)) the idea is to replace x: y: with only one argument function: anArgument <primitive: #primitiveNativeCall module: #NativeBoostPlugin> ^ self call: #( int function (int anArgument@1, int anArgument@2)) or even function: aPoint <primitive: #primitiveNativeCall module: #NativeBoostPlugin> ^ self call: #( int function (int aPoint@x, int aPoint@y)) Yes this last example breaks the encapsulation a little bit by acceding directly to the instance variable of aPoint... but... well another example will be: function_arg1: a arg2: b <primitive: #primitiveNativeCall module: #NativeBoostPlugin> ^ self call: #( int function (int a@1, int a@2, int b@3, int b@1, int a@6)) Well that's all that I did this weekend. Attached to this mail you can find a file-out of these developments... they include: 1. the idea presented above 2. refactoring of NBFFICallout argument loader creation 3. a small "extension/fix" of the skipSpace method (in spec parser) to skip all separators not just spaces (think about a header definition with tabs) Well that's it folks, enjoy Cheers -- Dr. Ciprian TEODOROV IngÃ©nieur DÃ©veloppement CAO tÃ©l : 06 08 54 73 48 mail : ciprian.teodorov(a)gmail.com www.teodorov.ro

[Pharo-project] [UPD] New VMs available.
by Torsten Bergmann Oct. 26, 2012

Hi Igor, thanks for the updated VM set. I used version 1.4. of ConfigurationOfAthens with the new NBCog VM's. The CairoLibraryLoader class #getLibraryPath is lacking the switch for the windows DLL which can be fixed by adding: (NativeBoost platformId = NativeBoostConstants win32PlatformId) ifTrue: [ ^ 'libcairo-2.dll' ]. After that it is working on Windows too. Can you give me access on Squeaksource so I can add it or will you integrate it? Also it would be nice to have a #stable in ConfigurationOfAthens and a copy of ConfigurationOfAthens moved to the 1.4 repo (NativeBoost also). This would allow easy installation via in-image ConfigurationBrowser. Especially since the Pharocast points to the outdatet version 1.1: http://www.pharocasts.com/2012/06/athens-and-native-boost-at-work.html Would make access, adoption and life a little bit easier ... Thx Torsten
