OK, I successfully loaded Seaside, Bootstrap and Magritte into Pharo 7.0.1 (32 and 64 bit) on Win10.
If anybody needs the 'how-to', here's what I did: - Install stable version of Magritte3 from Catalog Browser (marked as Pharo 7.0 compatible) - Install stable version of Bootstrap from Catalog Browser (marked as Pharo 7.0 compatible) Bootstrap project includes Seaside and it takes a couple of minutes to load. The load order - firstly Magritte3 and then Bootstrap - is important, otherwise I am getting this error: Loading 3.5.1 of ConfigurationOfMagritte3...MetacelloConflictingProjectError: Load Conflict between existing BaselineOfGrease [baseline] from github://SeasideSt/Grease:master/repository and ConfigurationOfGrease release1.2 from http://smalltalkhub.com/mc/Seaside/MetacelloConfigurations/main Sometimes, the Bootstrap / Seaside project leads to an error message from Iceberg saying that the path/file name is too long. -- Sent from: http://forum.world.st/Pharo-Smalltalk-Users-f1310670.html
