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  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 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.
