There are four steps:

  1. Compile C++ library code to object file (using g++)
  2. Create shared library file (. SO) using gcc –shared.
  3. Compile the C++ code using the header library file using the shared library (using g++)
  5. Run the executable (using a. out)

  2. Dynamic or shared libraries – are loaded when a program is launched and loaded into memory and binding occurs at run time.
