gccmakedep

gccmakedep(1)						      General Commands Manual						     gccmakedep(1)

NAME

       gccmakedep - create dependencies in makefiles using 'gcc -M'

SYNOPSIS

       gccmakedep [ -sseparator ] [ -fmakefile ] [ -a ] [ -- options -- ] sourcefile ...

DESCRIPTION

       The  gccmakedep program calls 'gcc -M' to output makefile rules describing the dependencies of each sourcefile, so that make(1) knows which
       object files must be recompiled when a dependency has changed.

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

       -fmakefile
	      Filename.   This	allows	you to specify an alternate makefile in which gccmakedep 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 gccmakedep to look for in the  makefile.   The
	      default is "# DO NOT DELETE".

       -- options --
	      If  gccmakedep  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, gccmakedep 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.

SEE ALSO

       gcc(1), make(1), makedepend(1).

AUTHOR

       The version of the gccmakedep included in this X.Org Foundation release was originally written by the XFree86 Project based  on	code  sup-
       plied by Hongjiu Lu.

       Colin Watson wrote this manual page, originally for the Debian Project, based partly on the manual page for makedepend(1).
