MKDEP(1)                     BSD Reference Manual                     MKDEP(1)

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      Write the include file dependencies to file, instead of the de-
             fault ``.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 use-
             ful for programs whose source is contained in a single module.
