I tried to find the right answer to my question but I couldn't, that's why I am here now.
Can I sell the application that I developed but contains some open source libraries? Or do I have to find people that created those libraries and ask them for permissions/pay them?
That might be a silly question but I really need to know how that works. I am currently developing mobile app that uses someone else's library (hosted on Google Code) and I don't know if I should mention that to my client?
Thanks for any help, marqss
It depends on the open source license of each library. You'll need to examine the licenses individually to determine what you can legally do with their libraries. For instance, the GPL puts some very severe restrictions on what you can do with an application linking to a GPL library. (It's a copyleft license, its goal is for you to also license your app's source openly; thus it's both very open and very restrictive.) The LGPL has fewer restrictions. An MIT-style license is much freer. Some projects roll their own. Others use CreativeCommons licenses. You get the idea.
