ExtUtils::MM_VMS - methods to override UN*X behaviour in
ExtUtils::MakeMaker
SSYYNNOOPPSSIISS #
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 provided there.
This package overrides the implementation of these methods, not the
semantics.
MMeetthhooddss aallwwaayyss llooaaddeedd wraplist Converts a list into a string wrapped at approximately 80 columns.
MMeetthhooddss 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 _._p_m file whose name matches that
of the current directory (presumably the 'main' _._p_m 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.
_fixin_replace_shebang (override)
Helper routine for MM->ffiixxiinn(()), overridden because there's no such
thing as an actual shebang line that will be interpreted by the
shell, so we just prepend $Config{startperl} and preserve the shebang
line argument for any switches it may contain.
maybe_command (override)
Follows VMS naming conventions for executable files. If the name
passed in doesn't exactly match an executable file, appends _._E_x_e (or
equivalent) to check for executable image, and _._C_o_m to check for DCL
procedure. If this fails, checks directories in DCL$PATH and finally
_S_y_s_$_S_y_s_t_e_m_: for an executable file having the name specified, with or
without the _._E_x_e-equivalent suffix.
pasthru (override)
The list of macro definitions to be passed through must be specified
using the /MACRO qualifier and must not add another /DEFINE
qualifier. We prepend our own comma here to the contents of
$(PASTHRU_DEFINE) because it is often empty and a comma always
present in CCFLAGS would generate a missing qualifier value error.
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 when you 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 _._c_o_m or
_._p_l and tries again, since it's customary 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 separator between a directory path and a filename on VMS.
init_main (override)
init_tools (override)
Provide VMS-specific forms of various utility commands.
Sets DEV_NULL to nothing because I don't know how to do it on VMS.
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 semantics. 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
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.
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.
_xsbuild_replace_macro (override)
There is no simple replacement possible since a qualifier and all its
subqualifiers must be considered together, so we use our own utility
routine for the replacement.
_xsbuild_value (override)
Convert the extension spec to Unix format, as that's what will match
what's in the XSBUILD data structure.
dlsyms (override)
Create VMS linker options files specifying universal symbols for this
extension's shareable image(s), and listing other shareable images or
libraries to which it should be linked.
xs_obj_opt
Override to fixup -o flags.
dynamic_lib (override)
Use VMS Link command.
xs_make_static_lib (override)
Use VMS commands to manipulate object library.
static_lib_pure_cmd (override)
Use VMS commands to manipulate object library.
xs_static_lib_is_xs
extra_clean_files
Clean up some OS specific files. Plus the temp file used to shorten
a lot of commands. And the name mangler database.
zipfile_target
tarfile_target
shdist_target
Syntax for invoking shar, tar and zip differs from that for Unix.
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.
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.
maketext_filter (override)
Ensure 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 $Config{vms_prefix} is
used instead.
cd
oneliner
eecchhoo
perl trips up on "<foo>" thinking it's an input redirect. So we use
the native Write command instead. Besides, it's faster.
quote_literal
escape_dollarsigns
Quote, don't escape.
escape_all_dollarsigns
Quote, don't escape.
escape_newlines
max_exec_len
256 characters.
init_linker
catdir (override)
catfile (override)
Eliminate the macros in the output to the MMS/MMK file.
(File::Spec::VMS used to do this for us, but it's being removed)
eliminate_macros
Expands MM[KS]/Make macros in a text string, using the contents of
identically named elements of %$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
my $path = $mm->fixpath($path);
my $path = $mm->fixpath($path, $is_dir);
Catchall routine to clean up problem MM[SK]/Make macros. Expands
macros in any directory specification, in order to avoid juxtaposing
two VMS-syntax directories when MM[SK] is run. Also expands
expressions 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.
ffiixxppaatthh(()) checks to see whether the result matches the name of a
directory in the current default directory and returns a directory or
file specification accordingly. $is_dir can be set to true to force
ffiixxppaatthh(()) to consider the path to be a directory or false to force it
to be a file.
NOTE: This is the canonical version of the method. The version in
File::Spec::VMS is deprecated.
os_flavor
VMS is VMS.
is_make_type (override)
None of the make types being checked for is viable on VMS, plus our
$self->{MAKE} is an unexpanded (and unexpandable) macro whose value
is known only to the make utility itself.
make_type (override)
Returns a suitable string describing the type of makefile being
written.
