I modified the Cog config made by Marcus to sync with my changes in scripts. https://pharo-ic.lille.inria.fr/hudson/view/Cog/ i also added a new target for building - Stack VM (except that it not works now, because Hudson can't pick up the built artifacts despite VM built successfully -- lets wait for Marcus to fix that , since i'm not expert in Hudson :) ). Adding another two is also a piece of cake - just copy existing configuration and change destination directory and configuration class used for generating sources and build config. The script i made for Hudson can work even for macs, it takes 3 arguments: - git repo url - working subdirectory name where to place everything - cmake configuration class name (which build to perform) that's all you need to build VM from scratch using Hudson -- Best regards, Igor Stasenko AKA sig.
