The Roassal2 is not load in the image. I load it from Pharo Project Catalog. I select the Roassal2 project and do the Install stable version. ( a this point i have a strange dialog behaviour : when the system open a dialog with: Question Roassal2 has not been marked as tested for Pharo5.0! Do you want to continue (installation could fail )? when i i select the yes or no button the dialog with the same question is often redispaly. ) > Do not install anything before testings. Then if everything works proceed and > install one thing, only, then test it, then install the next one etc. After install the Roassal2 like above and do the VGTigerDemo runDemo answer the same error: ExternalLibraryFunction(Object)>>error: ExternalLibraryFunction(Object)>>externalCallFailed ExternalLibraryFunction(ExternalFunction)>>invokeWithArguments: AthensCairoSurface class>>primImage:width:height: AthensCairoSurface class>>extent:format: AthensCairoSurface class>>extent: VGTigerDemo>>initialize VGTigerDemo class(Behavior)>>new VGTigerDemo class>>runDemo Thanks, Dario > Moving step by step will help us pin point your problem > > I suspect maybe something went crazy , it happens from time to time in pharo, > recently I had a nasty corruption with Pharo 6.
