The basic structure of a makefile is as follows: target1: prerequisite1 Makefile Structure: Targets, Prerequisites (Dependencies), and Recipes The make command can then be used to conveniently run the instructions in the Makefile. Makefiles are text files that developers use to describe the build process for their programs. Build automation tools like Make allow developers to describe the build steps and execute them all at once. It would be very tedious for a developer to manually run all of the build steps in sequence each time they want to build their program. The process of choosing a compiler, identifying the set of source code files to be included, performing preperation steps, and compiling the code into its final form is called building, or the build process.

Whether or not to apply any special options in the compilation process.

The names and locations to put the compiled (output) programs.

The set of compiled (output) programs to create.

The names and locations of the source code (input) files to compile.Sometimes the compiler needs to be given certain pieces of information so it can properly do its job. A program that performs this conversion is called a compiler. This process is called compilation or compiling. This source code usually needs to be converted into a form that the computer can understand. Therefore, it is common to see C source files and cpp source files in projects that use makefiles. Make is often used for C or C++ programs being compiled on Linux systems. Source code consists of a set of files and folders that contain code.

Turning Source Code into a Programīefore getting straight into Makefiles, lets briefly cover how source code gets turned into an actual program that can run on a computer. In this article, we'll discuss how Make and Makefiles work at a high level, then as an example describe how Git's original Makefile works and walk through it line by line.
