      @alan_g pkg-config lists the include dir correctly (/usr/local/include/miroil). I also printed the include dirs in CMake and the directory was there. Running make with VERBOSE=1 shows that it does not get passed to the compiler for some reason:

        I can workaround the issue by adding the include directories to the target directly (see Commit). Weird issue...

          @jonius next issue is a failing test (ApplicationManager), which fails here.

          The demo runs into a segfault as well. (MIR_SERVER_CURSOR=null QT_QPA_PLATFORM=mirserver qmlscene qml-demo-shell/qml-demo-shell.qml).

          btw, I am on Ubuntu 16.04 in a VM.

            @jonius Not sure why you're seeing different things. Maybe something with the graphics setup in your VM?

            Can you run the mir examples? For example:

            $ mir-smoke-test-runner
            ...
            I: Smoke testing complete with returncode 0
            

            If that also shows problems, this solution might help (depending on your choice of VM):

              I am using VirtualBox. I am not sure how to apply the suggestions in the link. Which VM solution would you suggest? Otherwise I'll install the system again on a separate partition without VM.

                @jonius I don't have VirtualBox to hand to give detailed instructions. But it should work if you enable "the right" graphics options. Not sure what it's called. Something like 'passthrough' or '3D' maybe?

                  I was hit by this bug. Now with 3D acceleration enabled most of the smoke tests succeed. Only mir_demo_client_eglplasma still failes. And the unit test I mentioned above continues to fail as well. Will test on separate installation without VM this weekend.

                  MIR_SERVER_CURSOR=null QT_QPA_PLATFORM=mirserver qmlscene qml-demo-shell/qml-demo-shell.qml works partially. The circle rotates, but the mouse cursor is not visible and clicking the scale buttons results in file:///home/miroil/qtmir/demos/qml-demo-shell/qml-demo-shell.qml:28: Error: Unknown method parameter type: FormFactor.

                    That's sort of expected. I disabled the cursor in Mir because QtMir tries to set a zero sized image instead of hiding it. And Mir treats that as an error.

                    I've not looked at how it works for Lomiri. I suspect it renders its own cursor.

                      @alan_g installed Ubuntu 16.04 on my notebook directly via Ubuntu Touch (ISODrive is a great tool). Unfortunately the situation here is worse than in my VM on an Ubuntu 20.04 host. I guess the outdated amdgpu for my Radeon Vega 8 Graphics in Ubuntu 16.04 is to blame. The demo runs like in the VM, the same unit test fails, but many smoke tests fail:

                      I:     mir_demo_client_camera
                      I:     mir_demo_client_tooltip
                      I:     mir_demo_client_eglsquare
                      I:     mir_demo_client_eglplasma
                      I:     mir_demo_client_eglstateswitcher
                      I:     mir_demo_client_target
                      I:     mir_demo_client_scroll
                      I:     mir_demo_client_cursors
                      I:     mir_demo_client_egltriangle
                      I:     mir_demo_client_egldiamond_render_surface
                      I:     mir_demo_client_display_config
                      I:     mir_demo_client_eglcounter
                      I:     mir_demo_client_touch_validator
                      I:     mir_demo_client_animated_cursor
                      I:     mir_demo_client_pointer_confinement
                      I:     mir_demo_client_input_shapes
                      I:     mir_demo_client_eglflash
                      

                      So I guess best is to switch back to my VM? Is the failing tests something I could ignore for now?

                        Of course. It will get annoying, but if you know you didn't break the code...

                        You've clearly got enough working to try stuff out.

                          Hey folks,
                          I can make this slightly easier with a few handy env vars.

                          @alan_g said in Introducing Miroil:

                          sudo ln -s /usr/local/lib/qt5/plugins/platforms/libqpa-mirserver.so /usr/lib/x86_64-linux-gnu/qt5/plugins/platforms/
                          

                          Allows Qt to find the platform.

                          You can avoid this soft link by setting this env var instead:

                          export QT_QPA_PLATFORM_PLUGIN_PATH=/usr/local/lib/qt5/plugins/platforms
                          

                          @alan_g said in Introducing Miroil:

                          So Let's make that easier to find too:

                          sudo ln -s /usr/local/lib/qt5/qml/Unity/ /usr/lib/x86_64-linux-gnu/qt5/qml/
                          

                          Similarly, you can avoid the soft link again and point Qt directly to where those QML plugins live with:

                          export QML2_IMPORT_PATH=/usr/local/lib/qt5/qml
                          

                          Hope this helps
                          -G

                            during the QtMir build with make -j 6 all test I also had the fatal error described by @jonius :

                              @jonius can you PR your fix? It looks to tidy up the cmake code too.

                                @aury88 I'm not sure when I'll be at a computer where I can fix this. In the meantime you could google enough git magic to cherry-pick @jonius's fix.

                                UPDATE: I've pushed a fix for the build error. There's still the test failure noted above.

                                @Aury88 You can get the fix with git pull

                                        Well, I've fixed the compile error, but you modernized the code as well. I think that's still worth a PR.

                                          Oh! so I totally misunderstood that command...reading the documentation seemed to me git pull already encompass a git fetch and a git merge. also I tried the git pull after the make command and that confirmed the local branch was up-to-date. ok, i will try again after the fetch. thank you.

                                            @jonius next issue is a failing test (ApplicationManager), which fails here.

                                            I had a look over the weekend. The test is failing in the branch I based this off, and I didn't see an obvious cause for it.

                                            I probably need to find a better base branch for this work. I really find all these QtMir branches a mystery. Maybe the best one is one of those in the gitlab repo?
