What is GNU Lesser General Public License v2 1?

Is MIT LGPL compatible?
The LGPL allows to be used from non-free software (while MIT is even free software), so being a dependency is not a blocker. However as it’s a dependency you need to offer the source-code of it if you distribute your software.
Does LGPL require dynamic linking?
LGPL does not force you to use dynamic linking. You can instead, for instance, provide object files for your software that the user will be able to link (statically) to any version of the library.
Does LGPL allow static linking?

What is the GNU LGPL license?

When did the LGPL change its name?
The LGPL was revised in minor ways in the 2.1 point release, published in 1999, when it was renamed the GNU Lesser General Public License to reflect the FSF’s position that not all libraries should use it.
Is LGPL a weak copyleft license?
However, LGPL is slightly different from other weak copyleft licenses, like the Mozilla Public License or Eclipse Public License, due to its special safe harbor for dynamic linking integration. The LGPL is primarily applied to libraries.
