I would like to use PyQT5 and QT5 to create an -internal- application for a friend and his company. I would like to use PyQT GPL license and QT LGPL license.

To respect these licenses, I need to:

  • give him the source code when the application is done;
  • create a msgBox who define what QT is, with links to their licenses;
  • provide a copy of the GPL license;

Is it correct? Do I forget something?


provide a copy of the GPL license

You not only need to provide a copy of the GNU GPL, but you also need to release the internal application under the GNU GPL.

There is a small chance of compatibility issues between different versions of the GPL and LGPL that you should consider as well.
