Trolltech Ports Free Qt to Mac

6/25/2003 - Trolltech brings its successful dual licensing business model to the Mac. Trolltech released Qt/Mac under the GPL (GNU General Public License), in connection with Apple's World Wide Developer Conference (WWDC) 2003 in San Francisco.

Qt/Mac is the Mac port of Qt - a single-source, multiplatform C++ GUI toolkit that allows applications to run natively on Windows, Linux/Unix, and Mac OS X, all from the same codebase.

The GPL release of Qt/Mac allows Mac free software developers to use Qt free of charge. Any software produced with the GPL version of Qt/Mac (and any derivatives of this software) must also be released with full source code available under the GPL. Developers who wish to create commercial (proprietary or closed source) software can continue to do so using the existing Qt/Mac commercial licenses.

With the Qt/Mac GPL release, thousands of existing Free Software applications developed with Qt/X11 (Linux and various flavors of Unix) and Qt/Embedded (embedded Linux), can now be ported to the Mac OS X platform. Most of these applications only require a simple recompile for Mac OS X.

"Trolltech has offered both commercial and Free Software licensing options to developers, since its founding in 1994," says Trolltech President and co-founder Eirik Eng. "This dual licensing strategy has been key to Trolltech's success, and we are proud to now bring this business model to the Mac."

The GPL version of Qt/Mac is available for download from the Trolltech website:
