[править] NAME

    mkdep -- construct Makefile dependency list

[править] SYNOPSIS

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

[править] DESCRIPTION

    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
          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 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
          depend:
                  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.

[править] ENVIRONMENT

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

[править] FILES

    .depend  File containing list of dependencies.
