Difference between Static and Shared libraries
In programming, a library is a collection of pre-compiled code that can be reused by programs for specific functionality. Based on how the library code is linked and loaded, libraries are classified into two types − static libraries and shared (dynamic) libraries. Static Library A static library is a library whose code is copied directly into the target executable at compile time by the linker. The resulting executable is self-contained and does not depend on external library files at runtime. Static libraries use the extensions .a (Linux) or .lib (Windows). Shared Library A shared library (also ...
