Hi Everyone, I'm attempting to update to the latest Pharo7 image (918efe2, 32 bit), but am getting an error while loading OSsubprocess. The error occurs in FFISharedPool class>>initialize: initialize self flag: #removeIt. "This IF will be eliminated soon...only here temporary" (SystemVersion current highestUpdate >= 50558) ifTrue: [ SessionManager default registerToolClassNamed: self name ] ifFalse: [ Smalltalk addToStartUpList: self. ] because #highestUpdate is nil. The top of the stack is: UndefinedObject(Object)>>doesNotUnderstand: #'>=' FFISharedPool class>>initialize MCMethodDefinition>>postloadOver: [ :each | each postloadOver: (self obsoletionFor: each) ] in MCPackageLoader>>basicLoadDefinitions in Block: [ :each | each postloadOver: (self obsoletionFor: ...etc... Based on the method above, it looks like highestUpdate used to be set based on the image number, and has presumably broken during the move to Pharo 7 and git. Earlier Pharo 7 images had it set to 0, which doesn't sound right. Since a build number was recently introduced (fogbugz 20321), should the highestUpdate be set to 70000+buildNumber? E.g. this image has an identifier of: Pharo 7.0 Build information: alpha.build.56.sha.918efe28fa3e6ad485b059dbf4ce675fd4086cf6 So highestUpdate would be 70056. Thanks! Alistair
