If the xcb plugin is configured and built on a system where the config.tests/qpa/xcb-xlib config test passes, and used on a system where it wouldn't have passed, the xcb plugin will not work. Maybe that's what Konstantin meant? I guess the same goes for the xcb-poll-for-queued-event and xcb-glx, xcb-render, and xcb-poll-for-queued-event config tests. -- Samuel _______________________________________________ Development mailing list Development@qt-project.org http://lists.qt-project.org/mailman/listinfo/development
