Understanding the free license

 

Hi,

I’m currently learning C++ and I have been looking for and easy GUI and I think Qt is a good candidate but I would like to know what are my limitations with the free license.

Can some be so kind and explain how the free license works? Is this license referring to the distribution of the software I’m getting (Qt) or the software I will create?

I was reading the documentation but it’s a little complicated.

Sorry if my question doesn’t make any sense.

Thanks

Hi,

Qt is available under a commercial license from Digia and under the following free licences: GPL v3 [gnu.org] and LGPL v2 [gnu.org].

I am not an expert about licensing and it is a complicated topic. In my opinion LGPL fits your needs because it places copyleft restrictions on the Qt framework but does not apply these restrictions to your software that merely link with the Qt libraries.

Thank you all for your replies!

I will check the links.

Ok, this may be the answer to my question since all I need to do is create a simple application that will be used by 10 or so people where I work. I just don’t want to do the wrong thing.

Thanks
