     mkdep — construct Makefile dependency list


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


     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

                   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 cc as the preprocessor and to ignore system headers, one would use

                   env MKDEP_CPP="cc -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

     -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.


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

     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".


     .depend  File containing list of dependencies.


     cc(1), cpp(1), make(1)
