      Hello. What to do in this case?

      ./ut-qtcreator.sh     
      access control disabled, clients can connect from any host
      QStandardPaths: XDG_RUNTIME_DIR not set, defaulting to '/tmp/runtime-zorg'

      libGL error: image driver extension not found

      libGL error: failed to load driver: r600
      process 1: The last reference on a connection was dropped without closing the connection. This is a bug in an application. See dbus_connection_unref() documentation for details.
      Most likely, the application was supposed to call dbus_connection_close(), since this is a private connection.

        @boky are you using the project from the "add module" branch ?. I've noticed an issue with Morph qml dependencies. Try to comment the last line from the Dockerfile

            @boky oh i was wrong, not that line, but the one that try to install Morph.Web ( qmlplugin... )
            I've updated the branch so you can rebuild the image
            After re-read your post it seems that you're not trying the add_module branch.
            So here i've no idea.

            What OS are you working on ?.
            Is your clickable up to date ?

                • A more generic solution using clickable image:

                I'm trying this approach. The path variable should include the qml dir

                cd ~/docs/devel
                mkdir qml-module-ubuntu-components
                cd qml-module-ubuntu-components/
                docker cp silly_bose:/usr/lib/x86_64-linux-gnu/qt5/qml .
                export QML_IMPORT_PATH=~/docs/devel/qml-module-ubuntu-components/ 
                qtcreator # -> doesn't work
                export QML_IMPORT_PATH=~/docs/devel/qml-module-ubuntu-components/qml
                qtcreator # -> this works
                

                So, you should set the variable such that you find this one:

                ls -dl $QML_IMPORT_PATH/Ubuntu

                  mhm, so while this works now to resolve import Ubuntu.Components 1.3 in a .qml file, but it still does not find #include <QtQml> or #include <QDebug> in a .cpp file. any idea?

                    @doniks are you working with a clickable template? I guess QtCreator does not find Qt libs, you should check in settings Qt paths

                        have you installed locally QtQuickControl 2 ?
                        sudo apt install qtquickcontrols2-5-dev

                        you can see if any issue with paths in kits

                          Video showing the WIP of having qtcreator running above clickable image :

                          full code completion for all UT components and qml modules , and can launch directly the app, you can debug the c++ part also.
                          The demo covers python and c++ clickable template, and address-book-app

                              @Abuabdellah i don't know if Ubuntu.Components are installable on 19.10 but you can wait for the clickable ide qtcreator feature or try the 1st post Guide solutions

                                        Taking a new stab at this ... So, again resolving Ubuntu.Components in qml files works fine, but resolving Qt includes in cpp files does not. I have qtquickcontrols2-5-dev installed and I don't see anything screaming at me in the Kits section ... but maybe it's still wrong?! See attached. Qt version = None might be wrong?! But I can't select anything else.

                                        Update: In Kits -> Qt Versions there is nothing there. I guess that is the problem, but I can't figure out how to get anything in there ... I found some reports online that sudo apt install qt5-default might help, but it doesn't help me 😞

                                        Update2: Now I manually added /usr/lib/x86_64-linux-gnu/qt5/bin/qmake in Qt Versions, and selected that in the Kit, closed and reopened, but still doesn't find any QtStuff

                                          @doniks well it seems there is definitly an issue with Qt5 path. probably you may found resources around about that

                                            Just to share my experience for developping Apps with QtCreator:

                                            Should I use QtCreator from 16.04, ubuntu-sdk or can I use latest QtCreator form Qt online installer?
