102 Chapter 4 • Using GNU make This chapter contains information on how to write makefiles for software projects and provides sufficient information for a reader to write make- files for fairly complex projects. You can also refer to the reference at the end of this chapter for more comprehensive information about the make utility. To demonstrate the use of make , several examples are presented in this chapter. These examples demonstrate how make can be used for different objectives. These examples are simple and easy to understand and are explained in the text. However you may write makefiles in many different ways for the same object. Features of make that are discussed in this chapter are those most commonly used. Make has many additional, less commonly used, features that are not covered here and you may want to use these as well while designing your makefiles.

4.1 Introduction to GNU make

The make utility has been used for a very long time in all types of software development projects. There are open-source as well as commercial variants available from many vendors. The most common and popular distribution of make is the GNU make, which is open source and is available for almost all UNIX and Microsoft Windows platforms. All of the Linux distri- butions have the GNU make as a standard package with the development system. If you have installed development software from a distribution, you don’t need to install any additional soft- ware for make to work. The version of make currently installed can be displayed using the fol- lowing command. [rootconformix make] make -v GNU Make version 3.79.1, by Richard Stallman and Roland McGrath.
