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 output 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 speci-
       fied 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 unrecognized 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.
