Installing Qt for Automation
Pre-built Qt for Automation installation packages are available under a commercial license. Open source developers can build their own binaries from the sources that are available under the GNU General Public License version 3 (GPLv3). Further, Qt OPC UA can be built with the GNU Lesser General Public License (LGPLv3) license, as long as the open62541 backend is used.
Download Qt page helps you to find the license that suits your needs. The commercial license is associated with a Qt Account, which is required to install the product.
Qt for Automation is based on the Qt for Device Creation offering so the prerequisites are the same for both. For more information about how to install and configure these prerequisites on your development host, see Requirements for Linux/X11 and Requirements for Windows.
