[Automotive] Question about qt license.

[Alistair Adams]

Hello Josh,

You have two options:

1) Use open source, pay no license fee, but you need to abide by the rules of the open source licenses. In general that mean you need to give the end user (the person that buys the car) the freedom to update the LGPLv3 libraries. Car companies typically don’t want to do this for security reasons. However, I need to cover myself by prefacing this with the usual language that you should get your own legal advice on what is needed.

2) Use a commercial license, in which case you don’t need to worry about open source compliance. But for that there is a fee and that is how we fund future development and maintenance of Qt.

Regards
Alistair

Hello Alistair,


Thank you for your reply & giving good information.


I want to double check about what I understood.
Even though I open all of my application's source code, If my application is going into production, I have to pay license fee?


Thanks & Regards,
Josh.

Hello Josh,

The answer depends on whether you are going into production or not.

Take a read of a clarification we put out here https://lists.linuxfoundation.org/pipermail/automotive-discussions/2017-June/004410.html. I’d be happy to answer any questions you might still have.

Regards
Alistair

Hi all of qt members.


I am develping  on AGL(Automotive Grade Linux) with Qt.
Now I am using AGL 5.0.1 version that using Qt 5.8.0.


I found that Qt Open Source License Change from Qt 5.7.0.
(ref link : https://lists.linuxfoundation.org/pipermail/automotive-discussions/2016-January/001506.html)


I developed application launcher which is running on AGL(5.0.1) with Qt 5.8.0. It may be that launcher is release on embbeded target board.

My question is that if I open all of launcher source code(launcher) at AGL,
Can I get a free license? or I must have to pay license fee?



Thanks & Regards,
Josh.
