NAME

     md -- process raw dependency files produced by cpp -MD

SYNOPSIS

     md [-d] [-f] [-m makefile] [-u makefile] [-o outputfile] [-v] [-x] [-D c|d|m|o|t|D]

DESCRIPTION

     The md command basically does two things:

     Process the raw dependency files produced by the cpp -MD option.  There is one line in the file for every #include encountered, but there are
     repeats and patterns like .../dir1/../dir2 that appear which should reduce to .../dir2.  md canonicalizes and flushes repeats from the depen-
     dency list.  It also sorts the file names and "fills" them to a 78 character line.

     md also updates the makefile directly with the dependency information, so the .d file can be thrown away (see d option).  This is done to
     save space.  md assumes that dependency information in the makefile is sorted by .o file name and it procedes to merge in (add/or replace [as
     appropriate]) the new dependency lines that it has generated.  For time effeciency, md assumes that any .d files it is given that were cre-
     ated before the creation date of the "makefile" were processed already.  It ignores them unless the force flag [f] is given.

FLAG SUMMARY

     -d delete the .d file after it is processed

     -f force an update of the dependencies in the makefile even though the makefile is more recent than the .n file (This implies that md has
     been run already.)

     -m makefile specify the makefile to be upgraded.  The defaults are makefile and then Makefile

     -u makefile like -m above, but the file will be created if necessary

     -o outputfile specify an output file for the dependencies other than a makefile

     -v set the verbose flag

     -x expunge old dependency info from makefile

     -D c|d|m|o|t|D subswitch for debugging.  can be followed by any of "c", "d", "m", "o", "t", "D" meaning:

	      c       show file contents
	      d       show new dependency crunching
	      m       show generation of makefile
	      o       show files being opened
	      t       show time comparisons
	      D       show very low level debugging

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.
