Yes, it's possible. LGPLv3 does not place any restrictions on hardware distribution.

Just make sure to grant your users the freedoms specified by the LGPLv3.

@Isaach
to add up to @JKSH
For LGPLv3 and HW this means you must grant access to the device upon user request, so hes able to replace the LGPL libs with different ones.
You may want to read about so called "tivoization"

Thanks for the answer,
I still have a doubt about the tools, is it possible to use Creator and rcc Compiler with LGPL v3 license?

Hi,

The license of Qt Creator itself is unrelated to the license of the libraries you use.

The LGPL applies to your created derivative work only - which is using LGPL libraries. The LGPL part of your application must be interchangeable, while your closed source part (can basically almost have any license you like). I am not a lawyer btw ;)

Ok, now I understand the concept,
what I would like to check is if QT Creator and
rcc Compiler are development tools for commercial license only or not.

Thank you for your help.

You can use them for open source projects too.

@Isaach The open source licenses usually do not matter for tools. GCC for example is licensed under more restrictive GPL but can be used for open source and commercial (closed source) projects.
