The next release of Qt will be released under the LGPL license
Good news for people developing graphical applications for embedded Linux systems. Nokia, the new owners of Trolltech, announced they will release the next version of the Qt graphical library under the LGPL license. This means that developers will be able to create applications based on the Qt library, with the license of their choice, free software / open source or proprietary.
As we explained in our Choosing graphical libraries for embedded systems presentation, Qt is more than a graphical library. It also offers a complete development framework, with development tools, data structures, threads, networking, XML parsing utilities making application development easier. All these features, and the fact that Qt directly run on top of the Linux framebuffer, also make it possible to create systems with a feature-rich interface without having to drag and build numerous dependencies.
Another bonus is that Qt supports multiple operating systems, making your applications easily portable. If you’ re not allowed to use Linux yet, write your applications with Qt, and once all OS related dependencies are removed, switch to your favorite OS without even letting your boss know
