Q: Go where (which forum) to ask a licensing-related question?
-
I am asking the below question in the wrong forum, but don't know where to ask it. I bet if I ask in The Lounge, someone will post go <there>. Here's hoping!
Situation:
I have previously developed a Windows background process (written in C++). It is closed-source, distributed as binary, for profit. It has no user interface, but receives and transmits signals allowing control by an external interface. It has no connection with Qt.I am considering using Qt to develop an open-source (LGPL) GUI application, to communicate with that process to allow user control. This GUI, in addition to being open-source, is intended to be one of several GUI options available to users, who may freely use, adopt, share, or even replace GUIs - but not the process with which the GUI communicates.
Question:
If I choose Qt to create and maintain this GUI app, and only the GUI app, is the open-source license available to me? Will my development, or for-profit distribution, of the non-Qt background process be constrained in any way? -
Hi and welcome to devnet,
WARNING: I am not a lawyer.
License questions should be asked to a lawyer not a forum.
That said, you have here two separate products that are not related to each other. As you wrote your GUI application uses a publique interface to communicate with your closed source application so you can use Qt's OpenSource license for that part.

SGaist, many thanks for your thoughts. :-)
