Qt for HarmonyOS development with 6.12.0 Beta2

With Qt Online Installer, you can install binaries for host platforms via "Desktop" item under "Qt 6.12.0 Beta2", including Windows and macOS.

macOS(Apple Silicon)

For examples, you have everything installed at ~/QtSDK. Your host build will be at ~/QtSDK/6.12.0/macos . You can install "HarmonyOS" item under "Qt 6.12.0 Beta2", then you will get it at ~/QtSDK/6.12.0/harmonyos_arm64_v8a .

For DevEco Studio and SDK, you need to install DevEco Studio 6.1.0 Release(DevEco Studio for Mac(ARM) 6.1.0.860(3.4GB)) via https://developer.huawei.com/consumer/cn/deveco-studio/ . Then you will have SDK with API 23 at /Applications/DevEco-Studio.app/Contents/sdk/default/openharmony .

Get Additional Packages via https://wiki.qt.io/Building_Qt6_for_HarmonyOS#Additional_Packages , you can put them at .local/opt/ohos/additional-packages .

Set SDK path locally(which is from CI setup)

$ sudo mkdir -p /opt/harmonyos/command-line-tools/sdk/default/
$ cd /opt/harmonyos/command-line-tools/sdk/default/
$ sudo ln -s /Applications/DevEco-Studio.app/Contents/sdk/default/openharmony ./openharmony

Trying to build an example

$ cd ~/QtSDK/Examples/Qt-6.12.0/widgets/gallery
$ mkdir build
$ cd build
$ ~/QtSDK/6.12.0/harmonyos_arm64_v8a/bin/qt-cmake -DCMAKE_FIND_ROOT_PATH=~/.local/opt/ohos/additional-packages ..
$ cmake --build . --parallel
$ ~/QtSDK/6.12.0/macos/bin/harmonydeployqt --verbose --hvigor /Applications/DevEco-Studio.app/Contents/tools/hvigor/bin/hvigorw --input ./gallery-harmony-deployment-settings.json

Then you can use DevEco Studio to open the project under ~/QtSDK/Examples/Qt-6.12.0/widgets/gallery/build/libgallery-harmonyos , sign the package, build it and deploy it to device.
