Deploy configurations in the Project mode Run Settings handle the packaging of the application as an executable and copying it to a location you want to run the executable at. The files can be copied to a location in the file system of the development PC or a mobile device.
When you deploy the application for the Symbian Device target, Qt Creator automatically generates a Symbian installation system (SIS) file in the project folder and copies it to the connected device. You can sign the SIS file and wrap it in a Nokia Smart Installer for Symbian package. You can test and debug the application on the device.
When you deploy the application on a Linux-based device target, such as Embedded Linux, Harmattan, or Maemo5, Qt Creator copies the application files to the connected device. You can test and debug the application on the device. You can create Debian installation packages for MeeGo Harmattan and Maemo 5 devices.
When you are ready to publish the application on a publishing channel, you must make sure that the installation file meets the requirements for publishing and installing applications to the target devices.
