    I found the mistake. In json file the names of the outputs were wrong. The real name is the name found by eglfs/kms. I found it from debug console of eglfs. I activate it with 'export QT_LOGGING_RULES="qt.qpa.*=true" The real name is "HDM1,HDM2".

    Hi, check that all Objective-C files using your static library have an extension .mm (not .m) (If ViewController.mm is the only file calling into your static library then it's ok now.) Check that you have a valid libHello.a file in your directory /Users/vietanh/build-Hello-Qt_6_2_2_for_iOS_Simulator/Debug-iphonesimulator, start a Terminal and type: ar -t /Users/vietanh/build-Hello-Qt_6_2_2_for_iOS_Simulator/Debug-iphonesimulator/libHello.a the output should be: __.SYMDEF SORTED Hello.o In Xcode, check that you have the the linking directive: -L /Users/vietanh/build-Hello-Qt_6_2_2_for_iOS_Simulator/Debug-iphonesimulator -l Hello (note: -l libHello or -l libHello.a do not work)

    @Quantum1982 said in Raspbian 2 player chess game: Thanks. I see that QGraphicsPixmapItem has a ShapeMode property. Can one set transparency with this ? If you think of MaskShape, it still mentions that the source must have an alpha channel. It's also expensive. @Quantum1982 said in Raspbian 2 player chess game: Also, do you have an idea as to why the pixmap items are not being added to the scene ? Check the coordinates of your items.

    Tried using a QtService specifically instead of a regular Android service. And this works, it keeps the socket alive in the background. Only problem is that it never creates the service, causes the screen to go black and outputs this repeatedly: E BufferQueueProducer: [SurfaceView - com.agragps.agragps/org.qtproject.qt.android.bindings.QtActivity@ffd32b0@0[20018]#0] query: BufferQueue has been abandoned E BufferQueueProducer: [SurfaceView - com.agragps.agragps/org.qtproject.qt.android.bindings.QtActivity@ffd32b0@0[20018]#0] dequeueBuffer: BufferQueue has been abandoned I Adreno : DequeueBuffer: dequeueBuffer failed E BufferQueueProducer: [SurfaceView - com.agragps.agragps/org.qtproject.qt.android.bindings.QtActivity@ffd32b0@0[20018]#0] query: BufferQueue has been abandoned E BufferQueueProducer: [SurfaceView - com.agragps.agragps/org.qtproject.qt.android.bindings.QtActivity@ffd32b0@0[20018]#0] dequeueBuffer: BufferQueue has been abandoned I Adreno : DequeueBuffer: dequeueBuffer failed W libAgraGPS_armeabi-v7a.so: QEGLPlatformContext: eglSwapBuffers failed: 300d On an older device: E BufferQueueProducer: [SurfaceView - com.agragps.agragps/org.qtproject.qt.android.bindings.QtActivity@718e731@0#0] dequeueBuffer: BufferQueue has been abandoned W libAgraGPS_armeabi-v7a.so: QEGLPlatformContext: eglSwapBuffers failed: 300d Made a minimal reproduction and reported it as a bug: https://bugreports.qt.io/browse/QTBUG-99691

    I think I figured it out. Looks like Qt creator has a specific version it is compatible with. This can be found at <Qt install location>\Tools\QtCreator\share\qtcreator\android\sdk_definitions.json. As for version Qt 6.2.2 and Qt creator 6.0.1, the JSON file contains: { "common": { "sdk_tools_url": { "linux": "https://dl.google.com/android/repository/commandlinetools-linux-6609375_latest.zip", "linux_sha256": "89f308315e041c93a37a79e0627c47f21d5c5edbe5e80ea8dc0aac8a649e0e92", "windows": "https://dl.google.com/android/repository/commandlinetools-win-6609375_latest.zip", "windows_sha256": "40bba20275180194bebf89bb58c74d712bb93cc401f36bd2f8f32383acf9826c", "mac": "https://dl.google.com/android/repository/commandlinetools-mac-6609375_latest.zip", "mac_sha256": "2c3822db1c916655223e5ee8ce0fbf6b73d0b99012045c9dc8eaa6a5736c0c55" }, "sdk_essential_packages": { "default": ["platform-tools", "platforms;android-30", "cmdline-tools;latest"], "linux": [], "mac": [], "windows": ["extras;google;usb_driver"] } }, "specific_qt_versions": [ { "versions": ["default"], "sdk_essential_packages": ["build-tools;30.0.2", "ndk;21.3.6528147"], "ndk_path": "ndk/21.3.6528147" }, { "versions": ["5.12.[0-5]", "5.13.[0-1]"], "sdk_essential_packages": ["build-tools;28.0.2", "ndk;19.2.5345600"], "ndk_path": "ndk/19.2.5345600" } ] } That means , it supports: NDK 21.3.6528147 Latest command line tools Android API 30 Google USB driver Build tools 30.0.2
