make

MAKE(1) 						      General Commands Manual							   MAKE(1)

NAME

       make - a program for maintaining large programs

SYNOPSIS

       make [-f file] [-iknpqrst] [option] ... [target]

OPTIONS

       -f     Use file as the makefile

       -i     Ignore status returned by commands

       -k     On error, skip to next command

       -n     Report, but do not execute

       -p     Print macros and targets

       -q     Question up-to-dateness of target

       -r     Rule inhibit; do not use default rules

       -s     Silent mode

       -t     Touch files instead of making them

EXAMPLES

       make kernel	   # Make kernel up to date

       make -n -f mfile    # Tell what needs to be done

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 .s files from .c files.  Here is a sample makefile .

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