[править] NAME

    mkdep -- construct Makefile dependency list

[править] SYNOPSIS

    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 dependen-
    cies 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 gcc as the preprocessor and to ignore
    system headers, one would use
                  env MKDEP_CPP="gcc -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 Makefile.
    -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 use-
            ful 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
    MKDEP_CPP       Specifies the preprocessor to use.  The default is "${CC}
    MKDEP_CPP_OPTS  Specifies the non-CFLAGS options for the preprocessor.
                    The default is "-M".
