In software development, a build is the process of converting

source code In computing, source code, or simply code, is any collection of code, with or without comments, written using a human-readable programming language, usually as plain text. The source code of a program is specially designed to facilitate the w ...

files into standalone software artifact(s) that can be run on a computer, or the result of doing so.

Functions

Building software is an end-to-end process that involves many distinct functions. Some of these functions are described below.

Version control

The

Code quality

Also known as static program analysis/static code analysis this function is responsible for checking that developers have adhered to the seven axes of code quality: comments, unit tests, duplication, complexity, coding rules, potential bugs and architecture & design. Ensuring a project has high-quality code results in fewer bugs and influences nonfunctional requirements such as maintainability, extensibility and readability; which have a direct impact on the ROI for a business.

Compilation

This is only a small feature of managing the build process. The compilation function turns source files into directly executable or intermediate objects. Not every project will require this function. While for simple programs the process consists of a single file being compiled, for complex software the source code may consist of many files and may be combined in different ways to produce many different versions.

The build utility typically needs to compile the various files, in the correct order. If the source code in a particular file has not changed then it may not need to be recompiled ("may not" rather than "need not" because it may itself depend on other files that have changed). Sophisticated build utilities and linkers attempt to refrain from recompiling code that does not need it, to shorten the time required to complete the build. A more complex process may involve other programs producing code or data as part of the build process and software.
