How to Create and Utilize Static Libraries Using g ?

Creating and Using Static Libraries with g

In software development, it's often desirable to package reusable code into modular units called libraries. Static libraries are a type of library that are linked with an executable at compile time. This article will guide you through the process of creating and using a static library using g , the GNU Compiler Collection.

Creating a Static Library

To create a static library from header.cpp and header.hpp:

• Compile header.cpp to create a.o object file:

  g++ -c header.cpp

• Create or add the object file to a static library:

  ar rvs header.a header.o

Using a Static Library

To use the header.a library in another .cpp code:

• Compile the code with the library as a linkage:

  g++ main.cpp header.a

  This will link the code with the library, including the functions and data defined in header.cpp and header.hpp.
