NAME    [Toc]    [Back]

     mkdep - construct Makefile dependency list

SYNOPSIS    [Toc]    [Back]

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

DESCRIPTION    [Toc]    [Back]

     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.
