DESCRIPTION

Make is a program that is normally used for developing large programs consisting of multiple files. It keeps track of which object files depend on which source and header files. When called, it does the minimum amount of recompilation to bring the target file up to date.

The file dependencies are expected in makefile or Makefile , unless another file is specified with -f. Make has some default rules built in, for example, it knows how to make .o files from .c files. Here is a sample makefile .

	d=/user/ast		# d is a macro
	program:	head.o tail.o	# program depends on these
		cc -o program head.o tail.o	# tells how to make program
		echo Program done.	# announce completion
	head.o:	$d/def.h head.c	# head.o depends on these
	tail.o:	$d/var.h tail.c	# tail.o depends on these

A complete description of make would require too much space here. Many books on UNIX discuss make . Study the numerous Makefiles in the MINIX 3 source tree for examples.
