MKDEP(1)		FreeBSD	General	Commands Manual		      MKDEP(1)

NAME
     mkdep -- construct	Makefile dependency list

SYNOPSIS
     mkdep [-ap] [-f file] [flags] file	...

DESCRIPTION
     The mkdep utility takes a set of flags for	the C compiler and a list of C
     source files as arguments and constructs a	set of include file dependen-
     cies which	are written into the file ``.depend''.	An example of its use
     in	a Makefile might be:

	   CFLAGS= -O -I../include
	   SRCS= file1.c file2.c

	   depend:
		   mkdep ${CFLAGS} ${SRCS}

     where the macro SRCS is the list of C source files	and the	macro CFLAGS
     is	the list of flags for the C compiler.

     The user has the ability to change	the preprocessor and preprocessor
     options used.  For	instance, to use gcc as	the preprocessor and to	ignore
     system headers, one would use

	   depend:
		   env MKDEP_CPP="gcc -E" MKDEP_CPP_OPTS=-MM mkdep \
			   ${CFLAGS} ${SRCS}

     The options are as	follows:

     -a	     Append to the output file,	so that	multiple mkdep's may be	run
	     from a single Makefile.

     -f	     Write the include file dependencies to file, instead of the
	     default ``.depend''.

     -p	     Cause mkdep to produce dependencies of the	form:

		   program: program.c

	     so	that subsequent	makes will produce program directly from its C
	     module rather than	using an intermediate .o module.  This is use-
	     ful for programs whose source is contained	in a single module.

ENVIRONMENT
     CC		     Specifies the C compiler to use.  The specified compiler
		     is	expected to have options consistent with the GNU C
		     compiler.

     MKDEP_CPP	     Specifies the preprocessor	to use.	 The default is	"${CC}
		     -E".

     MKDEP_CPP_OPTS  Specifies the non-CFLAGS options for the preprocessor.
		     The default is "-M".

FILES
     .depend  File containing list of dependencies.

SEE ALSO
     cc(1), cpp(1), make(1)

HISTORY
     The mkdep command appeared	in 4.3BSD-Tahoe.

FreeBSD	10.1			 June 6, 1993			  FreeBSD 10.1
