Can I sell my own PyQt4 app built with cx_freeze?

I know PyQt4 has GPL licence. But I'm confused:

How can I sell my app built with cx_freeze?

Can I do it legally? what should I do otherwise?

Do compiled py files also mean source code?

I don't want to change my code for PySide, which has LGPL. I want to sell PyQt4 built with cx_freeze if it is legal.

Solution

  • IANAL but here is a quick summary.

    1. Yes, you can sell it even though it is GPL.

    2. However, since PyQt4 is GPL, then your entire application is also GPL which means anyone who receives a copy (e.g., purchases it) is legally allowed to redistribute it for free or for money and there is nothing you can do to prevent it.

    3. Unless you purchase a commercial license for PyQt4 in which case you can maintain your proprietary license so long as you also follow the licensing restrictions/rules of any third-party libraries that you also use.
