Overview

This article shows a way to deploy Qt application to target platform with needed Qt library dependencies. The installation machine does not need Qt to be installed.

Qt application folder hierarchy

Place all required Qt run-time libraries and plugins to a directory hierarchy in a deployment machine. Say we have basic Qt application with simple GUI to show JPEG image, we might want to use this kind of hierarchy:

qt.conf
QtApp.exe
QtCore4.dll
QtGui4.dll
plugins/imageformats/qjpeg4.dll

Note that the Qt run-time libraries must be at the same folder with Qt application.

Defining Qt plugins locations with qt.conf

The Qt plugins location can be defined into qt.conf file so that the Qt application will find them:

[Paths]
Plugins = plugins
