Unsolved 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!
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.
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. :-)
