Can I copyright my software which uses GPL components?

Question

If I uses some libraries which are licensed as GPL in my software, does that mean I must disclose my source code as well? Is there a way to use free libraries and yet still keep my software code secret?

Answer 1

This may depend on the way you program it.
I believe that with libraries that are lgpl you can do this with the library being external to you program. Check the faqs to be sure.

Answer 2

No. GPL license retains the copyright to any such program or work, and a "work based on the Program" means either the Program or any derivative work under copyright law: that is to say, a work containing the Program or a portion of it, either verbatim or with modifications and/or translated into another language.

That's how it's worded on their license...
