Unfortunately, QCoreGraphicsPaintEngine needs to link against the Cocoa platform plugin to use classes/methods in QCocoaAutoReleasePool and QCocoaHelpers, but I can't figure out how to do that in qmake. QtGui and QtWidget both use these classes/methods as well, but I can't figure out how they are linking against the Cocoa plugin. Any hints on linking qtcocoa into cocoaprintersupport, or is that just not possible? That would be "not possible". QtGui and Widgets loads the Cocoa backend as a plugin and does not link agains it. I think the only options are either duplicating the neccesary code to support QCoreGraphicsPaintEngine in printsupport, or let it live in the cocoa plugin and "export" it using QCocoaNativeInterface. I don't like duplicating code so we went with the latter approach. Morten
