3.9. I’m not sure if I’m in compliance with the licensing scheme. I am confused with the open source licensing. What should I do?

It is always recommended to contact a lawyer familiar with open source licenses for a full review of your project to determine whether you can fulfill all of the obligations of applicable open source licenses (LGPLv3/GPLv2/GPLv3). You can have a high level view of your options with the “Get Started with Qt” guide in our Qt.io/download –page. In case there is any doubt on whether the requirements of the open source licenses can be met in full, the commercial licensing option of Qt is often the best choice to avoid legal setbacks. We’re also happy to talk to you about your situation, but we aren’t in the position to provide any legal guidance.
