    Hi all,

    I have been working on a project (commercial) that needs to work with KArchive library (part of the KDE). I use it for compressing and decompressing of files.
    Is there any legal stuff that I should be aware of? Can I just add KArchive libs to my app? My project is in a early stage so I would really love to know if I have chosen the right path.

    Tnx,
    Zgembo

      @zgembo You need to check the license. I just did it and it is GPLv2.
      That means: if you're going to distribute your software you will have to provide your source code to everyone asking for it.

        @jsulm Thank you for your reply. Is it possible to buy a licence?

            @Zgembo Don't take this as legal advice however here is a link with some descriptions for a good portion of the open sources licenses, what they allow, what you are expected to to do and what are some limitations of these licenses.
            https://choosealicense.com/licenses/

            If you are going to do commercial applications that use open source libraries it's probably a good idea to familiarize yourself with the finer details of each license. I've had to learn the hard way :)
