Yes. GPLed libraries can only be linked with GPLed (or weaker) code,
such as newBSD/MIT code or truly public-domain code.

Vice versa. The LGPL *does not* infect code that links to it, though it
*does* infect modified versions of the LGPLed code. The distinction
is not always easy to make in particular cases.

Then the LGPL makes sense. No version of your library can ever
become unfree, but unfree apps can be written using it.
