"make" - Manage Program Build Process

This section provides a tutorial example on how to use the 'make' tool to manage the build process of large programs that have multiple components.

What Is "make" - "make" is a utility tool to manage the build (compile, link, install, test, etc.) process of large programs that have multiple components. "make" can determine automatically which source code files of the program need to be recompiled, and issue the commands to recompile them. You can actually use "make" to describe any task where some files must be updated automatically from others whenever the others change.

You can follow this tutorial to install and verify the "make" tool on CentOS 8 systems.

1. Install "make":

herong$ sudo dnf install make
Package make-1:4.2.1-9.el8.x86_64 is already installed.
Dependencies resolved.
Nothing to do.

herong$ sudo dnf info make
Installed Packages

Summary      : A GNU tool which simplifies the build process for users
URL          : http://www.gnu.org/software/make/
License      : GPLv3+
Description  : A GNU tool for controlling the generation of executables and other
             : non-source files of a program from the program's source files. Make
             : allows users to build and install packages without any significant
             : knowledge about the details of the build process. The details about
             : how the program should be built are provided for make in the program's
             : makefile.

2. Verify "make" version:

herong$ make --version

GNU Make 4.2.1
Built for x86_64-redhat-linux-gnu
Copyright (C) 1988-2016 Free Software Foundation, Inc.

3. Create a "Makefile" with one task:

herong$ cat Makefile

compile: hello.cpp
  g++ -o hello hello.cpp

4. Run the task specified in the "Makefile":

herong$ make compile

g++ -o hello hello.cpp

5. Verify result:

herong$ ./hello
Hello world! From C++.

Ok. I can use the "make" tool to automate any tasks on my CentOS 8 computer now.
