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.
