Most permissive licenses and file-based copyleft licenses can be used together in a project without any conflict and that's great.
It's GPL that doesn't like any neighbors.</p>LGPL is a bad practicehttps://sandfox.me/misc/lgpl-bad-practice.html2024-11-24T21:26:00+02:002023-01-02T16:30:00+02:00Anton Smirnov<div><p>TL;DR: Don't use LGPL, avoid library-based copyleft in general.</p>

<p>The closest acceptable no-brainer replacement should be <a class="reference external" href="https://www.gnu.org/licenses/gpl-3.0.en.html">GNU GPL</a> with <a class="reference external" href="https://www.gnu.org/software/classpath/license.html">Classpath Exception</a>,
but the concept of library-based copyleft itself is flawed.
It's better to consider <a class="reference external" href="https://www.mozilla.org/en-US/MPL/">MPL</a> (less copyleft) or <a class="reference external" href="https://www.gnu.org/licenses/gpl-3.0.en.html">full GPL</a> (more copyleft).</p>
