NAME
       ccmakedep - create dependencies in makefiles using a C compiler

SYNOPSIS
       ccmakedep  [ cpp-flags ] [ -wwidth ] [ -smagic-string ] [ -fmakefile ] [ -oobject-suffix ]
       [ -v ] [ -a ] [ -cccompiler ] [ -- options -- ] sourcefile ...

DESCRIPTION
       The ccmakedep program calls a C compiler to preprocess each sourcefile, and uses the  out-
       put  to	construct  makefile  rules  describing	their dependencies.  These rules instruct
       make(1) on which object files must be recompiled when a dependency has changed.

       By default, ccmakedep places its output in the file named makefile if it exists, otherwise
       Makefile.   An  alternate makefile may be specified with the -f option.	It first searches
       the makefile for a line beginning with

	   # DO NOT DELETE

       or one provided with the -s option, as a delimiter for the dependency output.  If it finds
       it,  it	will  delete  everything following this up to the end of the makefile and put the
       output after this line.	If it doesn't find it, the program will append the string to  the
       makefile and place the output after that.

EXAMPLE
       Normally,  ccmakedep  will  be used in a makefile target so that typing 'make depend' will
       bring the dependencies up to date for the makefile.  For example,
	   SRCS = file1.c file2.c ...
	   CFLAGS = -O -DHACK -I../foobar -xyz
	   depend:
		   ccmakedep -- $(CFLAGS) -- $(SRCS)

OPTIONS
       The program will ignore any option that it does not understand, so you may  use	the  same
       arguments  that	you  would  for cc(1), including -D and -U options to define and undefine
       symbols and -I to set the include path.

       -a     Append the dependencies to the file instead of replacing existing dependencies.

       -cccompiler
	      Use this compiler to generate dependencies.

       -fmakefile
	      Filename.  This allows you to specify an alternate makefile in which ccmakedep  can
	      place  its output.  Specifying "-" as the file name (that is, -f-) sends the output
	      to standard output instead of modifying an existing file.

       -sstring
	      Starting string delimiter.  This option permits you to specify a	different  string
	      for ccmakedep to look for in the makefile.  The default is "# DO NOT DELETE".

       -v     Be verbose: display the C compiler command before running it.

       -- options --
	      If  ccmakedep encounters a double hyphen (--) in the argument list, then any unrec-
	      ognized arguments following it will be silently ignored.	A  second  double  hyphen
	      terminates  this	special  treatment.  In this way, ccmakedep can be made to safely
	      ignore esoteric compiler arguments that might normally be found in  a  CFLAGS  make
	      macro  (see  the	EXAMPLE section above).  -D, -I, and -U options appearing between
	      the pair of double hyphens are still processed normally.
