David check the squeak documentation on how to invoke external library with FFI. In pharo you have also alien (not tested on non intel - works on mac).

You do not have to recompile the vm to invoke external library. You define methods with specific pragmas annotations and the plugin code can be invoked.

One if these days we should write a better doc

VMMaker is published on SqueakSource. May be people with more experience will comment.

Tim Rowledge's explanation of VMMaker is here: http://wiki.squeak.org/squeak/2105 You will also find detailed instructions for VM builders along with the platform source code, which is maintained in a Subversion source code repository at squeakvm.org: http://squeakvm.org/cgi-bin/viewcvs.cgi/trunk/platforms/ For example, documentation on building for Unix (Linux) will be found here: http://squeakvm.org/cgi-bin/viewcvs.cgi/trunk/platforms/unix/doc/HowToBuildF...

It's nice to see there's more info about VM's than I thought, it would be even nicer to have it all gathered in just one place and up to date so it's easier to find it. Recently I started compiling my own unix VMs and as I was very confused at first, I decided to write a small guide for beginers to share my experiences (and to remember the steps after some time). It has some still-unanswered questions, but is thought for beginners, so it might help you.

Javier, This is a really good introduction. It explains the process clearly, and your diagram does a nice job of showing how the pieces come together. Well done! Regarding your question on the web page:

I've read that pharo uses a modified OE that supports full closures, but I don't know what changes you have to introduce to make them work. Anyway, I don't know if closures aren't used that much, or the default code already ingtegrates them but my pharo images never complained of my handmade OEs, so the VMMaker package seems to be the same for both Pharo and Squeak.

All current VMs provide closure support, which is included in the VMMaker package. If your image uses closures, then the VM supports them and there are no modifications required. Pharo, Squeak trunk, and Cuis images all use closures now, other others (e.g. SqueakLand) will probable have this added as time goes on. Dave
