NAME

       mkdep - construct Makefile dependency list

SYNOPSIS

       mkdep [ -f makefile ] [ -p ] flags file ...

DESCRIPTION

       Mkdep  takes a set of flags for the C compiler and a list of C source files as arguments and constructs a set of include file dependencies.
       It attaches this dependency list to the end of the file ``Makefile''.  An example of its use in a makefile might be:

	      CFLAGS= -O -I../include -I.
	      SRCS= file1.c file2.c

	      depend:
		   mkdep ${CFLAGS} ${SRCS}

       where the macro SRCS is the list of C source files and the macro
       CFLAGS is the list of flags for the C compiler.	The -f option
       provides mkdep with a name other than ``Makefile'' to be edited.
       If the -p option is provided, mkdep produces dependencies
       of the form ``program: program.c'' so that subsequent makes will
       produce program directly from its C module rather than using an
       intermediate .o module.	This is useful in directories that
       contain many programs, each of whose source is contained in a single
       C module.

NAME

     mkdep -- construct Makefile dependency list

SYNOPSIS

     mkdep [-ap] [-f file] [flags] file ...

DESCRIPTION

     The mkdep utility takes a set of flags for the C compiler and a list of C source files as arguments and constructs a set of include file
     dependencies which are written into the file ``.depend''.	An example of its use in a Makefile might be:

	   CFLAGS= -O -I../include
	   SRCS= file1.c file2.c

	   depend:
		   mkdep ${CFLAGS} ${SRCS}

     where the macro SRCS is the list of C source files and the macro CFLAGS is the list of flags for the C compiler.

     The user has the ability to change the preprocessor and preprocessor options used.  For instance, to use gcc as the preprocessor and to
     ignore system headers, one would use

	   depend:
		   env MKDEP_CPP="gcc -E" MKDEP_CPP_OPTS=-MM mkdep 
			   ${CFLAGS} ${SRCS}

     The options are as follows:

     -a      Append to the output file, so that multiple mkdep's may be run from a single Makefile.

     -f      Write the include file dependencies to file, instead of the default ``.depend''.

     -p      Cause mkdep to produce dependencies of the form:

		   program: program.c

	     so that subsequent makes will produce program directly from its C module rather than using an intermediate .o module.  This is useful
	     for programs whose source is contained in a single module.

ENVIRONMENT

     CC 	     Specifies the C compiler to use.  The specified compiler is expected to have options consistent with the GNU C compiler.

     MKDEP_CPP	     Specifies the preprocessor to use.  The default is "${CC} -E".

     MKDEP_CPP_OPTS  Specifies the non-CFLAGS options for the preprocessor.  The default is "-M".

FILES

     .depend  File containing list of dependencies.

HISTORY

     The mkdep command appeared in 4.3BSD-Tahoe.
