How Can windeployqt Simplify Qt 5 Deployment on Windows?

Simplifying Qt 5 Deployment on Windows using windeployqt

Deploying Qt applications on Windows has been a challenge, especially with the transition to Qt 5. This article explores a simplified approach using the windeployqt tool.

Unlike Qt4, copying DLLs alone is no longer sufficient for Qt5 deployment. Users had previously resorted to static builds, but these too proved unsuccessful. The solution lies in utilizing the dedicated windeployqt tool introduced in Qt 5.2.

Command-Line Usage of windeployqt

Execute windeployqt from the command line to view usage instructions. Here's a basic syntax:

windeployqt .exe_file

The tool scans the given .exe file for Qt dependencies and copies them accordingly.

Setting the QML Directory

Qt 5 applications utilize QML files. To ensure proper dependency detection, specify the QML directory using the --qmldir option.

windeployqt .exe_file --qmldir qml_directory

Testing the Deployment

To ensure completeness, test the deployment on a computer without the Qt SDK installed. Alternatively, temporarily rename the Qt directory to prevent the application from accessing missing files from there.

Conclusion

windeployqt significantly simplifies the deployment process for Qt 5 applications on Windows. By copying necessary dependencies and setting the QML directory, developers can ensure their applications will run smoothly on clean systems.
