Packages

Introduction

Qt Extended is available in a number of different editions. The available packages include:

EditionDescription
Qt Extended Commercial EditionIncludes all Qt Extended modules. Qt Extended is issued under a commercial license.
Qt Extended Opensource EditionIdentical to Qt Extended Commercial Package, but issued under the GNU General Public License version 2, which does not permit closed-source commercial development.

Note: For a complete list of applications please refer to Qt Extended Components.

The commercial Qt Extended targets companies involved in commercial Qt Extended application development, including those requiring support and maintenance. The Opensource package targets opensource developers, who will release the source code of their Qt Extended applications and any changes they make to Qt Extended itself. Support and maintenance are not provided for the Opensource release.

Qt Extended Source Packages

Qt Extended is released as a source code package (also referred to as an OEM Kit). These packages allow customers to customize Qt Extended to work on their particular device, to install and distribute Qt Extended on devices, and allow customers to develop their own Qt Extended applications.

To install and distribute Qt Extended on commercial devices both the Qt Extended OEM Kit and Qt Extended Runtime licenses are required.

Qt Extended Software Development Kit (SDK)

The Qt Extended SDK enables the development of Qt Extended applications.

The SDK contains a complete Software Development environment that can be installed and executed on both Linux and Windows. Within the environment Qt Extended based applications can be developed, compiled, and debugged and then installed onto a device such as the Greenphone.

The SDK is provided in binary format and includes:

To simplify debugging of Qt Extended itself, the user can install and build a Qt Extended source package inside the SDK.

Commercial Licensing

Commercial, proprietary and non-free software may only be written if the commercial editions of Qt Extended has been purchased. Various licenses and license agreements are available to suit the development and distribution needs of customers. If free software is going to be developed for release using a recognized open source license then the Qt Extended Opensource Edition should be used.

The purchase of a Qt Extended commercial edition includes technical support and upgrades.

Opensource Licensing

Free software comes with a license providing certain rights to users. In particular the rights to use the software, modify it, obtain its source, and to pass it on under the same terms. In this context the the term "free" is about rights, not money.

The Free Software Foundation (creators of the GNU GPL) refer to free in the sense of freedom not price .

We support the free software concept by providing the Qt Extended Opensource Edition. You can use this edition of Qt Extended to create free software, i.e. software that is licensed under the GNU GPL or a similarly recognized open source license.

This version of Qt Extended is provided with no support and no warranty. It is provided under the GNU General Public License, GPL.

Licensing Conditions

If you use the Qt Extended Opensource Edition, there are licensing conditions that the GNU GPL imposes to ensure that your users enjoy the freedoms guaranteed by the GPL. Users are entitled to:

These freedoms apply to all source code for all the modules your software is based on, regardless of whether they have been written by you or by others. The freedoms also apply to any associated interface definition files and include the scripts and control files used to control compilation and installation of the executable. This last freedom is necessary to ensure that users can exercise their rights.

This means the Qt Extended Opensource Edition cannot be used to develop software that will incorporate modules imposing conditions contradicting those of the GNU GPL. The GNU GPL conditions relate to, but are not limited to, software patents, commercial license agreements, copyrighted interface definitions and any sort of non-disclosure agreements. If your software is going to conflict with any of these conditions then the Qt Extended Opensource Edition is not appropriate and you must use the commercial editions of Qt Extended.
