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.
