How to Create and Use Static Libraries in C Using g

Creating Static Libraries with g

In the world of programming, static libraries provide a convenient way to reuse precompiled object code across multiple projects. To create a static library in g , understanding how to compile .cpp and .hpp files is essential.

Creating the Static Library (header.a)

To create a static library named header.a, follow these steps:

1. Compile the .cpp File to an Object File (.o):

   g++ -c header.cpp

   This generates an object file named header.o containing compiled code from header.cpp.

2. Create the Static Library and Add the Object File:

   ar rvs header.a header.o

   This creates the header.a static library and includes header.o within it.

Using the Static Library in Other Code

To use the header.a library in other .cpp code, such as test.cpp, follow this step:

g++ main.cpp header.a

This compiles test.cpp by linking it with the header.a library, allowing access to the precompiled code.

In essence, by creating a static library, you can efficiently reuse compiled code, reducing build times and promoting code reusability.
