Remember that if your application depends on compiler specific libraries, these must be redistributed along with your application.

For more information, see the Application Dependencies section. We'll cover the plugins shortly, but first we'll check that the application will work in a deployed environment: Either copy the executable and the Qt DLLs to a machine that doesn't have Qt or any Qt applications installed, or if you want to test on the build machine, ensure that the machine doesn't have Qt in its environment.

But the application's functionality will still be missing since we have not yet deployed the associated plugins. Plugins work differently to normal DLLs, so we can't just copy them into the same directory as our application's executable as we did with the Qt DLLs.

When looking for plugins, the application searches in a plugins subdirectory inside the directory of the application executable. So to make the plugins available to our application, we have to create the plugins subdirectory and copy over the relevant DLLs:.

Other plugins might be required depending on the features the application uses iconengines , imageformats. In addition, the archive must contain the following compiler specific libraries assuming Visual Studio To verify that the application now can be successfully deployed, you can extract this archive on a machine without Qt and without any compiler installed, and try to run it.

An alternative to putting the plugins in the plugins subdirectory is to add a custom search path when you start your application using QCoreApplication::addLibraryPath or QCoreApplication::setLibraryPaths.

One benefit of using plugins is that they can easily be made available to a whole family of applications. It's often most convenient to add the path in the application's main function, right after the QApplication object is created.

Once the path is added, the application will search it for plugins, in addition to looking in the plugins subdirectory in the application's own directory. Any number of additional paths can be added. When deploying an application compiled with Visual Studio, there are some additional steps to be taken.

First, we need to copy the manifest file created when linking the application. This manifest file contains information about the application's dependencies on side-by-side assemblies, such as the runtime libraries.

The manifest file needs to be copied into the same folder as the application executable. You do not need to copy the manifest files for shared libraries DLLs , since they are not used. If the shared library has dependencies that are different from the application using it, the manifest file needs to be embedded into the DLL binary. Since Qt 4. You can find more information about manifest files and side-by-side assemblies at the MSDN website.

The correct way to include the runtime libraries with your application is to ensure that they are installed on the end-user's system. Note: The application you ship must be compiled with exactly the same compiler version against the same C runtime version. This prevents deploying errors caused by different versions of the C runtime libraries.

Depending on configuration, compiler specific libraries must be redistributed along with your application. You can check which libraries your application is linking against by using the Dependency Walker tool. All you need to do is to run it like this:. This will provide a list of the libraries that your application depends on and other information. From Qt version 5.
