The GNU Lesser General Public License version 2.0 (LGPLv2) is an open-source software license that governs the use, distribution, and modification of software projects. It is a permissive free software license approved by the Free Software Foundation (FSF). The LGPLv2 is designed to allow developers to use LGPL-licensed code in both open-source and proprietary projects.
One of the key features of the LGPLv2 is that it provides more flexibility for linking with proprietary software compared to the regular GNU General Public License (GPL). Specifically, it allows for dynamic linking of a library under the LGPL with a proprietary application while still requiring any modifications to the library itself to be released under the LGPL.
It’s important to note that the LGPLv2 applies primarily to libraries. If you make changes to the library itself, those changes must be released under the LGPLv2. However, if you only use the library in your own program without making changes to the library code, you are not required to release your own code under the LGPLv2.
