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


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


See ExtUtils::MM_Unix for a documentation of the methods providedthere. This package overrides the implementation of these methods, notthe semantics. 

Methods always loaded

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


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 explanationof why this method overrides the MM_Unix method; see the ExtUtils::MM_Unixdocumentation for more details.
guess_name (override)
Try to determine name of extension being built. We begin with the nameof the current directory. Since VMS filenames are case-insensitive,however, we look for a .pm file whose name matches that of the currentdirectory (presumably the 'main' .pm file for this extension), and tryto find a "package" statement from which to obtain the Mixed::Casepackage name.
find_perl (override)
Use VMS file specification syntax and CLI commands to find andinvoke Perl images.
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 .Comto check for DCL procedure. If this fails, checks directories in DCL$PATHand finally Sys$System: for an executable file having the name specified,with or without the .Exe-equivalent suffix.
pasthru (override)
VMS has $(MMSQUALIFIERS) which is a listing of all the original command lineoptions. This is used in every invocation of make in the VMS Makefile soPASTHRU should not be necessary. Using PASTHRU tends to blow commands pastthe 256 character limit.
pm_to_blib (override)
VMS wants a dot in every file so we can't have one called 'pm_to_blib',it becomes 'pm_to_blib.' and MMS/K isn't smart enough to know that whenyou have a target called 'pm_to_blib' it should look for 'pm_to_blib.'.

So in VMS its pm_to_blib.ts.

perl_script (override)
If name passed in doesn't specify a readable file, appends .com and tries again, since it's customary to have file types on all filesunder VMS.
Use as separator a character which is legal in a VMS-syntax file name.
(override) Because of the difficulty concatenating VMS filepaths wemust pre-expand the DEST* variables.
No seperator between a directory path and a filename on VMS.
init_main (override)
init_others (override)
Provide VMS-specific forms of various utility commands, then handoff 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 toone second later than source file, since MMK interprets preciselyequal revision dates for a source and target file as a sign that thetarget needs to be updated.

init_platform (override)

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

init_VERSION (override)
Override the *DEFINE_VERSION macros with VMS semantics. Translate theMAKEMAKER filepath to VMS style.
constants (override)
Fixes up numerous file and directory macros to insure VMS syntaxregardless of input syntax. Also makes lists of filescomma-separated.
Clear the default .SUFFIXES and put in our own list.
cflags (override)
Bypass shell script and produce qualifiers for CC directly (but warnuser if a shell script for this extension exists). Fold multiple/Defines into one, since some C compilers pay attention to only oneinstance of this qualifier on the command line.
const_cccmd (override)
Adds directives to point C preprocessor to the right place whenhandling #include <sys/foo.h> directives. Also constructs CCcommand line a bit differently than MM_Unix method.
tools_other (override)
Throw in some dubious extra macros for Makefile args.

Also keep around the old $(SAY) macro in case somebody'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 compiler.
dlsyms (override)
Create VMS linker options files specifying universal symbols for thisextension's shareable image, and listing other shareable images or libraries to which it should be linked.
dynamic_lib (override)
Use VMS Link command.
static_lib (override)
Use VMS commands to manipulate object library.
Clean up some OS specific files. Plus the temp file used to shortena lot of commands.
Syntax for invoking shar, tar and zip differs from that for Unix.
install (override)
Work around DCL's 255 character limit several times,and useVMS-style command line quoting in a few cases.
perldepend (override)
Use VMS-style syntax for files; it's cheaper to just do it directly herethan to have the MM_Unix method call "catfile" repeatedly. Also, ifwe have to rebuild, use MM[SK] to do it.
makeaperl (override)
Undertake to build a new set of Perl images using VMS commands. SinceVMS does dynamic loading, it's not necessary to statically link eachextension into the Perl image, so this isn't the normal build path.Consequently, it hasn't really been tested, and may well be incomplete.
maketext_filter (override)
Insure that colons marking targets are preceded by space, in orderto distinguish the target delimiter from a colon appearing aspart of a filespec.
prefixify (override)
prefixifying on VMS is simple. Each should simply be:


which can just be converted to:


otherwise you get the default layout.

In effect, your search prefix is ignored and $Config{vms_prefix} isused instead.

perl trips up on ``<foo>'' thinking it's an input redirect. So we use thenative Write command instead. Besides, its faster.
256 characters.
Expands MM[KS]/Make macros in a text string, using the contents ofidentically named elements of %$self, and returns the resultas a file specification in Unix syntax.

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

   my $path = $mm->fixpath($path);   my $path = $mm->fixpath($path, $is_dir);

Catchall routine to clean up problem MM[SK]/Make macros. Expands macrosin any directory specification, in order to avoid juxtaposing twoVMS-syntax directories when MM[SK] is run. Also expands expressions whichare all macro, so that we can tell how long the expansion is, and avoidoverrunning DCL's command buffer when MM[KS] is running.

fixpath() checks to see whether the result matches the name of adirectory in the current default directory and returns a directory orfile specification accordingly. $is_dir can be set to true toforce fixpath() to consider the path to be a directory or false to forceit to be a file.

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