CGAL seems to do just about everything I need and a little more for my upcoming project. It can create polygons out of arc line segments and run boolean operations on them. It has spatial sorting packages already that would save me a lot of time regarding a few things and the whole library seems quite standardized and well planned.

I've got a meager budget and can likely not gather funds to buy the commercial licenses for those specific packages in CGAL

Possible Duplicate: Using LGPL library in a commercial Java application Hello guys! There is a project under the GNU Lesser GPL license. I want to use this project in my application. Can I sell my application using this license? In a nutshell, the idea of LGPL'd projects (usually libraries) is that you are free to use them as you wish in your own application, be it open or closed source, free or proprietary - as long as you publish the source code of the LGPL'd part (if you modify the LGPL'd part, you must publish the modified sources, under LGPL).

Can I use a LGPL library in my paid android application? I am not going to modify the LGPL lib, I just want to use it. Is it legal?

Very doubtful in the case of DEX file, as mentioned in previous comments. An alternative to a single DEX file is to make from a dependent library a separate application, released on

I don't know much about the LGPL/GPL when it comes to distributing programs (without a Qt license); If I made a program, could I statically link the libraries to the exe so I have a single file to distribute when: The program does not cost anything, it's just being distributed (closed source or open source)? When you have to pay for the program can you still statically link? No, if your program is closed source and you want to link against the LGPL version of Qt you must use dynamic linking. If you want to statically link then you must buy a license for Qt. To use LGPL code in your closed
