How do I deploy a Qt program in Windows?

Go deploy Qt cross-platform application by using windeployqt

1. Build Qt Code for Release.
2. Create a new folder to hold all the files associated with the deployment using this method.
3. Copy the Release binary file inside the new folder.
4. Find the path to ‘windeployqt’
5. Add to the user environment PATH variable.

1. Deploy your application with windeployqt/linuxdeployqt

1. Compile your binary in release mode.
2. Open the Qt developer console and type windeployqt “C:/folder/of/your/executable” (linuxdeployqt will be very similar)
3. All libraries required to run the application on another computer are copied to to your application folder.

Creating dll seems an easy task in Qt. In Qt creator, click File/New File or Project/Projects/Library/C++ Library, then simply choose a name, you will create a dll project. Click “build”, you will see the . dll generated in the debug or release directory.

For the per user install, the default installation will be a subdirectory called Qt in the current working directory. For the global install, the default location is /opt/Qt.

The DLLs are from C:/Qt/5.4/msvc2013/bin.

The Windows Deployment Tool The Windows deployment tool windeployqt is designed to automate the process of creating a deployable folder containing the Qt -related dependencies (libraries, QML imports, plugins, and translations) required to run the application from that folder.

It is quite possible that some other plugin, or another application which inserted itself into the PATH environment variable, has put Qt dlls in the applications folder. In that case, the plug-in will not start as it is expecting a different version of the DLL. Q1.

I’m trying to deploy my application on windows; after running qtenv2.bat and vcvarsall.bat, I launch windeployqt.exe. The tool successfully finds and deploy all the Qt5*.dll dependencies (even a dll I manually built, Qt5Pdf.dll), but fails to find a dependency to another dll I had to build to compile the program (in the specific, qca-qt5.dll).

In case Qt was built with the configure switch -relocatable turned off, windeployqt replaces the hardcoded local paths in Qt5Core.dll by relative ones. For Windows desktop applications, the required runtime files for the compiler are also copied to the deployable folder by default (unless the option –no-compiler-runtime is specified).
