Usually they are under /opt/myapp/plugins/platforms but I didn't see that directory?

In that case, I would use a virtual environment with the stuff specific to Qt.

I recommend to contact technical support regarding this. However, the Floating License Server (FLS) is being superseded by the Qt License Server (QLS). And the general plan is to phase out use of FLS over time. So going forward, it is best to check the respective API of QLS instead. https://doc.qt.io/qtlicenseserver/qls-overview.html https://doc.qt.io/qtlicenseserver/qls-restapi.html

@Anuj-Srivastava Are you sure you posted in the right sub-forum?

With change 733351 in Qt Gerrit now merged into the dev branch of qtbase, along with several other changes merged into the qt5 dev branch (see the harmonyos_upstream topic), qtbase dev now supports building on HarmonyOS 6.0.0 (API Level 20). If you are interested in building qtbase for HarmonyOS, please refer to the Qt Wiki page.

Hallo, danke für die Rückmeldungen. Habe jetzt im Internet folgende Anleitung gefunden: qt_generate_deploy_qml_app_script( TARGET MyApp OUTPUT_SCRIPT deploy_script ) install(SCRIPT ${deploy_script}) On installation, the application binary will be deployed, including the QML files and the shared libraries and assets of Qt that are used by the project. Again, the resulting directory is self-contained and can be packaged by tools like cpack. Das ganze in die cmake.txt geschrieben läuft ohne Fehler durch aber wo finde ich jetzt "OUTPUT_SCRIPT deploy_script" mfg

Hi, Akismet can be sensitive sometimes. What exactly did you want to add to your post ? I have not understood.
