CopperSpice Overview  1.5.2
Deploying on Windows

On Windows you will need to distribute different files depending on whether you link statically or dynamically.

Shared Libraries

When deploying your application using shared libraries, the correct CopperSpice libraries must be distributed along with your application. In addition, any plugin must be included and installed on the target system in the correct folders.

Linking your Application with Shared Libraries

Refer to our sample project files for details about how to compile and link your application.

Additional Libraries

Compiler specific libraries must be redistributed along with your application. You can check which libraries your application is linking against by using a Dependency Walker tool.

Creating the Application Package

To deploy your application include all the files in your 'deploy' folder. This folder was created during the 'make install' process.

If your application depends on compiler specific libraries, these must also be distributed with your application.

Plugins work differently to normal DLLs and can not simply be copied into the same directory as the application executable. When looking for plugins, your application will search for a folder called plugins. This folder must be a subdirectory under the directory of containing your application.

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


One benefit of using plugins is they can be made available to a whole family of applications.


Your application may also depend on one or more plugins, such as the JPEG image format plugin or a SQL driver plugin. Be sure to distribute any plugins that you need with your application. Each type of plugin should be located within a specific subdirectory (such as image formats or sqldrivers) within your distribution directory.

If you are deploying an application that uses WebKit, include all text codec plugins to support as many HTML encodings possible.

The following are the various alternatives to make sure that the plugins are found by your application.

  • Path Configuration This is the recommended approach since it provides the most flexibility.
  • Using QApplication::addLibraryPath() or QApplication::setLibraryPaths().
  • Using a third party installation utility or the target system's package manager to change the hard-coded paths in the CsCore library.

The Creating Plugins document outlines the important issues when building and deploying plugins. More information about deployment, refer to Deploying Plugins.
