ExtUtils::MM_VMS(3)
NAME
  ExtUtils::MM_VMS - methods to override UN*X behaviour in
  ExtUtils::MakeMaker

SYNOPSIS
   use ExtUtils::MM_VMS; # Done internally by ExtUtils::MakeMaker if needed

DESCRIPTION
  See ExtUtils::MM_Unix for a documentation of the methods provided there.
  This package overrides the implementation of these methods, not the
  semantics.

  Methods always loaded

  wraplist
      Converts a list into a string wrapped at approximately 80 columns.

  rootdir (override)
      Returns a string representing of the root directory.

  SelfLoaded methods

  Those methods which override default MM_Unix methods are marked
  "(override)", while methods unique to MM_VMS are marked "(specific)".	 For
  overridden methods, documentation is limited to an explanation of why this
  method overrides the MM_Unix method; see the ExtUtils::MM_Unix
  documentation for more details.

  guess_name (override)
      Try to determine name of extension being built.  We begin with the name
      of the current directory.	 Since VMS filenames are case-insensitive,
      however, we look for a .pm file whose name matches that of the current
      directory (presumably the 'main' .pm file for this extension), and try
      to find a "package" statement from which to obtain the Mixed::Case
      package name.

  find_perl (override)
      Use VMS file specification syntax and CLI commands to find and invoke
      Perl images.

  path (override)
      Translate logical name DCL$PATH as a searchlist, rather than trying to
      "split" string value of "$ENV{'PATH'}".

  maybe_command (override)
      Follows VMS naming conventions for executable files.  If the name
      passed in doesn't exactly match an executable file, appends .Exe (or
      equivalent) to check for executable image, and .Com to check for DCL
      procedure.  If this fails, checks directories in DCL$PATH and finally
      Sys$System: for an executable file having the name specified, with or
      without the .Exe-equivalent suffix.

  maybe_command_in_dirs (override)
      Uses DCL argument quoting on test command line.

  perl_script (override)
      If name passed in doesn't specify a readable file, appends .com or .pl
      and tries again, since it's customary to have file types on all files
      under VMS.

  file_name_is_absolute (override)
      Checks for VMS directory spec as well as Unix separators.

  replace_manpage_separator
      Use as separator a character which is legal in a VMS-syntax file name.

  init_others (override)
      Provide VMS-specific forms of various utility commands, then hand off
      to the default MM_Unix method.

  constants (override)
      Fixes up numerous file and directory macros to insure VMS syntax
      regardless of input syntax.  Also adds a few VMS-specific macros and
      makes lists of files comma-separated.

  cflags (override)
      Bypass shell script and produce qualifiers for CC directly (but warn
      user if a shell script for this extension exists).  Fold multiple
      /Defines into one, since some C compilers pay attention to only one
      instance of this qualifier on the command line.

  const_cccmd (override)
      Adds directives to point C preprocessor to the right place when
      handling #include <sys/foo.h> directives.	 Also constructs CC command
      line a bit differently than MM_Unix method.

  pm_to_blib (override)
      DCL still accepts a maximum of 255 characters on a command line, so we
      write the (potentially) long list of file names to a temp file, then
      persuade Perl to read it instead of the command line to find args.

  tool_autosplit (override)
      Use VMS-style quoting on command line.

  tool_sxubpp (override)
      Use VMS-style quoting on xsubpp command line.

  xsubpp_version (override)
      Test xsubpp exit status according to VMS rules ($sts & 1 ==> good)
      rather than Unix rules ($sts == 0 ==> good).

  tools_other (override)
      Adds a few MM[SK] macros, and shortens some the installatin commands,
      in order to stay under DCL's 255-character limit.	 Also changes
      EQUALIZE_TIMESTAMP to set revision date of target file to one second
      later than source file, since MMK interprets precisely equal revision
      dates for a source and target file as a sign that the target needs to
      be updated.

  dist (override)
      Provide VMSish defaults for some values, then hand off to default
      MM_Unix method.

  c_o (override)
      Use VMS syntax on command line.  In particular, $(DEFINE) and
      $(PERL_INC) have been pulled into $(CCCMD).  Also use MM[SK] macros.

  xs_c (override)
      Use MM[SK] macros.

  xs_o (override)
      Use MM[SK] macros, and VMS command line for C compiler.

  top_targets (override)
      Use VMS quoting on command line for Version_check.

  dlsyms (override)
      Create VMS linker options files specifying universal symbols for this
      extension's shareable image, and listing other shareable images or
      libraries to which it should be linked.

  dynamic_lib (override)
      Use VMS Link command.

  dynamic_bs (override)
      Use VMS-style quoting on Mkbootstrap command line.

  static_lib (override)
      Use VMS commands to manipulate object library.

  manifypods (override)
      Use VMS-style quoting on command line, and VMS logical name to specify
      fallback location at build time if we can't find pod2man.

  processPL (override)
      Use VMS-style quoting on command line.

  installbin (override)
      Stay under DCL's 255 character command line limit once again by
      splitting potentially long list of files across multiple lines in
      "realclean" target.

  subdir_x (override)
      Use VMS commands to change default directory.

  clean (override)
      Split potentially long list of files across multiple commands (in order
      to stay under the magic command line limit).  Also use MM[SK] commands
      for handling subdirectories.

  realclean (override)
      Guess what we're working around?	Also, use MM[SK] for subdirectories.

  dist_basics (override)
      Use VMS-style quoting on command line.

  dist_core (override)
      Syntax for invoking VMS_Share differs from that for Unix shar, so
      "shdist" target actions are VMS-specific.

  dist_dir (override)
      Use VMS-style quoting on command line.

  dist_test (override)
      Use VMS commands to change default directory, and use VMS-style quoting
      on command line.

  install (override)
      Work around DCL's 255 character limit several times,and use VMS-style
      command line quoting in a few cases.

  perldepend (override)
      Use VMS-style syntax for files; it's cheaper to just do it directly
      here than to have the MM_Unix method call "catfile" repeatedly.  Also,
      if we have to rebuild Config.pm, use MM[SK] to do it.

  makefile (override)
      Use VMS commands and quoting.

  test (override)
      Use VMS commands for handling subdirectories.

  test_via_harness (override)
      Use VMS-style quoting on command line.

  test_via_script (override)
      Use VMS-style quoting on command line.

  makeaperl (override)
      Undertake to build a new set of Perl images using VMS commands.  Since
      VMS does dynamic loading, it's not necessary to statically link each
      extension into the Perl image, so this isn't the normal build path.
      Consequently, it hasn't really been tested, and may well be incomplete.

  nicetext (override)
      Insure that colons marking targets are preceded by space, in order to
      distinguish the target delimiter from a colon appearing as part of a
      filespec.
