ExtUtils::MM_VMS(Perl Programmers Reference GExtUtils::MM_VMS(3p)


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

SYNOPSIS
         Do not use this directly.
         Instead, use ExtUtils::MM and it will figure out which MM_*
         class to use for you.

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.

       Methods

       Those methods which override default MM_Unix methods are
       marked "(override)", while methods unique to MM_VMS are
       marked "(specific)".  For overridden methods, documenta-
       tion is limited to an explanation of why this method over-
       rides the MM_Unix method; see the ExtUtils::MM_Unix docu-
       mentation 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.

       maybe_command (override)
           Follows VMS naming conventions for executable files.
           If the name passed in doesn't exactly match an exe-
           cutable file, appends .Exe (or equivalent) to check
           for executable image, and .Com to check for DCL proce-
           dure.  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-equiva-
           lent suffix.

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

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

       init_DEST
           (override) Because of the difficulty concatenating VMS
           filepaths we must pre-expand the DEST* variables.

       init_DIRFILESEP
           No seperator between a directory path and a filename
           on VMS.

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

           DEV_NULL should probably be overriden with something.

           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.

       init_platform (override)
           Add PERL_VMS, MM_VMS_REVISION and MM_VMS_VERSION.

           MM_VMS_REVISION is for backwards compatibility before
           MM_VMS had a $VERSION.

       platform_constants
       init_VERSION (override)
           Override the *DEFINE_VERSION macros with VMS seman-
           tics.  Translate the MAKEMAKER filepath to VMS style.

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

       special_targets
           Clear the default .SUFFIXES and put in our own list.

       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

ExtUtils::MM_VMS(Perl Programmers Reference GExtUtils::MM_VMS(3p)


           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.

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

       tools_other (override)
           Throw in some dubious extra macros for Makefile args.

           Also keep around the old $(SAY) macro in case some-
           body's using it.

       init_dist (override)
           VMSish defaults for some values.

             macro         description                     default

             ZIPFLAGS      flags to pass to ZIP            -Vu

             COMPRESS      compression command to          gzip
                           use for tarfiles
             SUFFIX        suffix to put on                -gz
                           compressed files

             SHAR          shar command to use             vms_share

             DIST_DEFAULT  default target to use to        tardist
                           create a distribution

             DISTVNAME     Use VERSION_SYM instead of      $(DISTNAME)-$(VERSION_SYM)
                           VERSION for the name

       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 com-
           piler.

       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.

ExtUtils::MM_VMS(Perl Programmers Reference GExtUtils::MM_VMS(3p)


       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.

       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.

       clean_subdirs_target
             my $make_frag = $MM->clean_subdirs_target;

           VMS semantics for changing directories and rerunning
           make very different.

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

       zipfile_target (o)
       tarfile_target (o)
       shdist_target (o)
           Syntax for invoking shar, tar and zip differs from
           that for Unix.

       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



perl v5.8.5                 2002-11-06                          4





ExtUtils::MM_VMS(Perl Programmers Reference GExtUtils::MM_VMS(3p)


           call "catfile" repeatedly.  Also, if we have to
           rebuild Config.pm, use MM[SK] to do it.

       makefile (override)
           Use VMS commands and quoting.

       find_tests (override)
       test (override)
           Use VMS commands for handling subdirectories.

       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.  Con-
           sequently, 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.

       prefixify (override)
           prefixifying on VMS is simple.  Each should simply be:

               perl_root:[some.dir]

           which can just be converted to:

               volume:[your.prefix.some.dir]

           otherwise you get the default layout.

           In effect, your search prefix is ignored and $Con-
           fig{vms_prefix} is used instead.

       oneliner (o)
       echo (o)
           perl trips up on "<foo>" thinking it's an input redi-
           rect.  So we use the native Write command instead.
           Besides, its faster.

       quote_literal
       escape_newlines
       max_exec_len
           256 characters.

       init_linker (o)
       eliminate_macros
           Expands MM[KS]/Make macros in a text string, using the
           contents of identically named elements of %$self, and
           returns the result as a file specification in Unix
           syntax.

           NOTE:  This is the canonical version of the method.
           The version in File::Spec::VMS is deprecated.

       fixpath
           Catchall routine to clean up problem MM[SK]/Make
           macros.  Expands macros in any directory specifica-
           tion, in order to avoid juxtaposing two VMS-syntax
           directories when MM[SK] is run.  Also expands expres-
           sions which are all macro, so that we can tell how
           long the expansion is, and avoid overrunning DCL's
           command buffer when MM[KS] is running.

           If optional second argument has a TRUE value, then the
           return string is a VMS-syntax directory specification,
           if it is FALSE, the return string is a VMS-syntax file
           specification, and if it is not specified, fixpath()
           checks to see whether it matches the name of a direc-
           tory in the current default directory, and returns a
           directory or file specification accordingly.

           NOTE:  This is the canonical version of the method.
           The version in File::Spec::VMS is deprecated.

       os_flavor
           VMS is VMS.
