Compiling the source code files can be tiring, especially when you have to include several source files and type the compiling command every time you need to compile. Makefiles are the solution to simplify this task.
The command should be presented yours own C sourcing file in the shell directory, followed the naming convention xshcommand.c. The following is the code for main.cpp source file − Makefiles are special format files that help build and manage the projects automatically.įor example, let’s assume we have the following source files. the command table (shell/shell.c) must be updated, and that make file (shell/Makerules) must build who line inclusive the function. The second rule is the default rule used by make to create a. There are numerous directives available in various forms. The make program on your system may not support all the directives. So please check if your make supports the directives we are explaining here. The ifeq directive begins the conditional, and specifies the condition. Variable substitution is performed on both arguments and then they are compared. The lines of the makefile following the ifeq are obeyed if the two arguments match otherwise they are ignored. The ifneq directive begins the conditional, and specifies the condition.
It contains two arguments, separated by a comma and surrounded by parentheses.
