How do you create a library in Linux?

How do you create a library in Linux?

  1. Step 1: Implement the library source files and save them with .
  2. Step 2: Compile and generate object files of both .c files using gcc compiler.
  3. Step 3: Create the library file using archive tool ar.
  4. Step 4: Create a header file with the prototypes of library functions and save with .h file extension.

Can we create library in C?

Creating Libraries :: Static Library Setup First thing you must do is create your C source files containing any functions that will be used. Your library can contain multiple object files. After creating the C source files, compile the files into object files. This will create a static library called libname.

How do you create a library in Unix?

What is dynamic library in C?

Dynamic libraries are a collection of object files which are referenced at build time to give the executable information how they will eventually be used, but they aren’t used until run time. In other words, these objects are dynamically linked into executables that use them.

How do I create a static library in Linux?

Steps to create a static library Let us create and use a Static Library in UNIX or UNIX like OS.

  1. Create a C file that contains functions in your library. /* Filename: lib_mylib.c */
  2. Create a header file for the library.
  3. Compile library files.
  4. Create static library.
  5. Now our static library is ready to use.
