Hi Genode Comunity

We want to share our basic support of QT 5.5 on GenodeOS. The on going development is in our GenodeOS fork at Github:

https://github.com/xeos-team/genode/tree/qt5_5

We worked to support the basic elements of Qt, based on the support of Qt 5.1. This work is not finished yet, but it can be used by the community. Based on the support of Qt 5.1 we have reorganized a bit the Qt modules, acording the modules on Qt 5.5. This is the list of the components supported and a list of examples of Qt that we have tested on GenodeOS:

* Qt Core o qt5_core_contiguouscache.run o qt5_core_savegame.run o qt5_core_semaphores.run o qt5_core_waitconditions.run * Qt Gui o qt5_gui_analogclock.run o qt5_gui_openglwindow.run o qt5_gui_rasterwindow.run * Qt Widgets o qt5_widgets_animatedtiles.run o qt5_widgets_appchooser.run o qt5_widgets_calculator.run o qt5_widgets_chart.run o qt5_widgets_digitalclock.run o qt5_widgets_dynamiclayouts.run o qt5_widgets_elasticnodes.run o qt5_widgets_lighting.run o qt5_widgets_mainwindow.run o qt5_widgets_moveblocks.run o qt5_widgets_pathstroke.run o qt5_widgets_puzzle.run o qt5_widgets_sliders.run o qt5_widgets_standarddialogs.run o qt5_widgets_stickman.run o qt5_widgets_tetrix.run o qt5_widgets_textedit.run o qt5_widgets_trafficlight.run o qt5_widgets_undo.run * Qt Network o qt5_network_dnslookup.run o qt5_network_fortuneserver.run o qt5_network_threadedfortuneserver.run o * Qt Websockets o qt5_websockets_echoserver.run o qt5_websockets_simplechat.run * Qt Xml o qt5_xml_dombookmarks.run o qt5_xml_htmlinfo.run o qt5_xml_xmlstreamlint.run

At this point we are having some troubles in the support. In some examples, we are getting this message when the Qt application finished

Genode::Signal_session_component::submit(Genode::Signal_context_capability, unsigned int)::<lambda(Genode::Signal_context_component*)>: invalid signal-context capability

On the XML module, there is a little problem, I think that Qt isn't recognizing the EOF in the XMLs files. Have tested it and it parse the XML file but fails at EOF. I'm reviewing this trying to fix it on Qt or the libc integration with Qt. The UDP sockets are not working on GenodeOS yet. We are planning continue working on the other Qt modules. If someone have any suggestion to our support problems, or is interested to help us in the support of Qt 5.5 is welcome.

Best regards
