Hi Mustafa, You got already ver robust answer to your questions in other answers. Here I will just summarize some points to observe. If your software is derived from a GPL code, as stated by the license itself, your software has to be GPL licensed as well and it has a series of obligations (described in license) about full source code distribution. If our software is developed using LGPL libraries, again as stated in in the license itself, ou may keep your code closed, but there is a series of obligations described in the license itself. This is how a large number of commercial closed source software (e.g. Oracle Database) can exist and be sold targeting platforms like Linux based systems If your is derived, or based, of proprietary/comercial software with non GPL/LGPL licenses ou have to study those licenses and act according to them. Bundle QGis with your software may not be a problem, provided that you fulfill your obligations as stated by the license. Other possibility is ou sell/license your software only and let the the clients know what version it will support. If you are investing in commercialization of your software, as suggested in other answer to our questions, the better way to be safe is consult a lawyer specialized in IP and Licensing.
