NAME

       mkdep — construct Makefile dependency list

SYNOPSIS

       mkdep [-ap] [-f file] [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 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 options are as follows:

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

       -f file
               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.
