The Free Pascal compiler supports smartlinking and the creation of libraries. However, the
default behaviour is to compile each unit into 1 big object le, which will be linked as
a whole into your program. Shared libraries can be created on any platform except
MS-DOS.
It is also possible to take existing units and put them together in 1 static or shared library (using
the ppumove tool, section 8.7, page 407).
