Hello,

Apologies for my late reply.

Unless otherwise stated (in my non-legal computer professional opinion!) you can choose which one of these licenses to follow: in this case, either the GPLv2 or the LGPLv2. You can pick the one which suits your needs most. In this case, you would remove the line that relates to the license that you do not choose.

However, if the author states that both must stay then both must stay.

I haven’t had a read of the GPL/LGPL recently but I believe there is a clause that if it is used in commercial software then you have to publish the source code and allow others to make derivatives? This may impact whether you choose to use it on a commercial project or not. Just something to have a look into if you haven’t already.

You are correct though, unless otherwise stated, remove the license that you don’t choose :).

Kind regards,
David.

I downloaded some JavaScript library that released under GPL/LGPL. And developer who owns that librariy shows licensing detail in his line of code like this.

* @license http://www.opensource.org/licenses/gpl-2.0.php GPLv2
* @license http://www.opensource.org/licenses/lgpl-2.1.php LGPLv2

So do I need to remove line of GPL license from his source code in case I pick LGPL for my commercial software?

If not, how do people know which license I need to abide by?
