-C dir, -directory=dir: These options are used to change the directory before executing the makefile.-B, -always-make: These options are used to unconditionally make all targets.-b, -m: These options are used to ignore the compatibility for the different versions of the make command.The make command facilitates various options to make it more specific. And the target is an executable file, and it is created after the execution of make command. The dependencies specify the relation of each file with the source files. The commands are separated with a tab in the new line. The first line is the dependency line, and the subsequent lines are considered as actions or commands. These standards are in two parts and separated by a new line. These standards are helpful for the system to understand what command we want to execute. So, it may be an extremely time taking process. If we have a large program with many source files, we must recompile all the dependent files. It keeps track of recent files, so only update those files which are required. It is recommended to create a separate directory for it. It is not allowed to create more than one makefile. The makefile contains targets and commands for execution. It is a special file that contains the shell commands that we create to maintain the project. The make command invokes the execution of the makefile. It will save a lot of time in the final compilation of the project. It will build the main target after the dependencies are built.įor example, if we want to change only one source file and we execute the make command so, this will compile only the object file that is connected with that source file.
If dependencies are not specified, it will search for the dependency and will build it. When we execute the make command, it searches for the makefile and scans it to find the target and access its dependencies. These arguments are specified in 'Makefile.' The makefile contains the targets as well as associated actions related to these targets. The make command takes targets as arguments. It is not just limited to programs we can use it to describe other tasks also. In this section, we will use C++ programs since the C++ programming language is an object-oriented language, but you can use any language installed on your machine. Also, it issues the necessary orders to recompile them. The main motive of the make command is to determine a large program into parts and to check whether it needs to be recompiled or not. Further, it handles the compilation process of the sizeable projects. It assists developers to install and compile many utilities from the terminal.
In Linux, it is one of the most frequently used commands by the developers. The Linux make command is used to build and maintain groups of programs and files from the source code.
