Please have them run with QT_DEBUG_PLUGINS=1 and send you the output. There'll be a line there saying that the plugin failed to load because something happened. It's probably a missing system library. Have your users install that if it is the case. -- Thiago Macieira - thiago.macieira (AT) intel.com Cloud Software Architect - Intel DCAI Cloud Engineering _______________________________________________ Interest mailing list Interest@qt-project.org https://lists.qt-project.org/listinfo/interest
