NAME make – utility for building and maintaining groups of programs. DESCRIPTION make bread sauce The purpose of the make utility is to determine automatically which pieces of a large program need to be recompiled, and issue the commands to recompile them.

In fact, make is not limited to programs. You can use it to describe any task where some files must be updated automatically from others whenever the others change. To prepare to use make, you must write a file called the makefile that describes the relationships among files in your program, and the states the commands for updating each file. In a program, typically the executable file is updated from object files, which are in turn made by compiling source files. These options are ignored for compatibility with other versions of make. Change to directory dir before reading the makefiles or doing anything else. This is typically used with recursive invocations of make.

Print debugging information in addition to normal processing. The debugging information says which files are being considered for remaking, which file-times are being compared and with what results, which files actually need to be remade, which implicit rules are considered and which are applied—everything interesting about how make decides what to do. If the FLAGS are omitted, then the behavior is the same as if -d was specified. Give variables taken from the environment precedence over variables from makefiles. Specifies a directory dir to search for included makefiles.
