Can not load Aliens FFI in Squeak 4.1
 
|
Hi everybody!
Could you please help me? I'm experiencing the following trouble: when I'm loading the Alien FFI (from the squeaksource or from the .mcz files manually) in Squeak 4.1, I'm getting the DNU expection Array>>createMethod:header: The Alien-Prereq module was already loaded. May be I've missed some dependencies? Or Alien does not work with the 4.1 and I should install an earlier version? Thanks, Dmitry |

Hello Igor!
Thank you for the patch, it has helped and now it looks like the Alien is loaded... But. When I'm sending an #asAlien message to a simple string, e.g. 'xmessage something' asAlien The executions fails with the primitiveFailed exception here: Alien >> sizeFieldPut: size "<Integer> ^<Integer>" <primitive: 'primSizeFieldPut' error: errorCode module: 'IA32ABI'> ^self primitiveFailed I assume that the Alien-Core package was not loaded properly. What am I doing wrong? 2010/5/5, Igor Stasenko <[hidden email]>: > On 5 May 2010 14:42, Dmitry Matveev <[hidden email]> wrote: >> Hi everybody! >> >> Could you please help me? >> >> I'm experiencing the following trouble: when I'm loading the Alien FFI >> (from >> the squeaksource or from the .mcz files manually) in Squeak 4.1, I'm >> getting >> the DNU expection Array>>createMethod:header: >> > > This happens, when you using an obsolete way of encoding > a method's trailer - bytes instead of instance of CompiledMethodTrailer. > > Here the fix: > > MethodNode>>generate > "The receiver is the root of a parse tree.

You're probably missing the plugin IA32ABI

Hello Eliot,
I have not found it in my system (I use the Squeak vm from the Debian Unstable repository). I've downloaded the Squeak vm for Linux from the official site and even have not found this plugin in that archive. Where I can obtain it for the i686 GNU/Linux system (or for Windows as a last resort)? Building from the source is also accepted.

The platform-side sources still need to be fixed. I were able to build it after manually patching 3-4 places (see other thread dedicated to it few days ago). And image-side code can't be loaded cleanly on 4.1 images. > Background: http://bugs.squeak.org/view.php?id=7475 > > Dave > -- Best regards, Igor Stasenko AKA sig. |

It seems I have a Bad Karma.
I've downloaded the 4.0.3.2202 source tarball from the squeakvm.org; I've built it successfully but I did not found the IA32ABI plugin :( The directory Cross/plugins/IA32ABI exists and I see the source code there, but it seems that CMake did not build it since there's no appropriate CMakeFile entries for this plugin. How can I integrate the IA32ABI plugin right into the build process? 2010/5/6 Igor Stasenko <[hidden email]>

No bad karma, but I think you will get better results if you start using the very latest versions of the platform source code and VMMaker for source code generation. You can get the most up to date platform sources like this: $ svn co http://squeakvm.org/svn/squeak/trunk squeak-svn-source Use VMMaker loaded from SqueakSource, and do "VMMaker updateFromServer" to make sure it is up to date. Do not use the source code in platforms/unix/src/ because this is a saved copy of sources generated from VMMaker at some time in the past. Instead, use VMMaker to generate your own sources. Do this for some tips on running configure: $ ../platforms/unix/cmake/configure --help And be sure to use the --CFLAGS=<flags> option to point to your own sources (the sources that you generated from VMMaker).

Hello Dave,
Thank you for advice. This day I've spent trying to build the Squeak entirely from the svn using the VMMaker. It was a real pain. I've took the http://pharocasts.blogspot.com/2010/03/build-squeak-vm-on-linux.html podcast as tutorial. At first, I've tried to install the VMMaker from the SqueakSource in my current Squeak 4.1 image. It has failed to install (and now I cannot remember why). Then I've tried to install the VMMaker from the SqueakSource into the Pharo 1.0 image. It was successful, so I've run the VMMakerTool from there. It looked like the VMMaker has prepared the sources directory properly; I've replaced the appropriate directory from the svn version by the generated one, ran the configure and make, I've got the IA32ABI folder in my build directory with the cmake' makefiles (yeah!), but it did not helped :( The compiled VM still fails to execute my simple 'asAlien' code with the same error. My head is spinning. Could somebody produce a step-by-step scenario for the complete idiots like me how to get it all working right? 2010/5/6 David T. Lewis <[hidden email]>
