ExtUtils::MM_VMS(3)
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, 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.
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.
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.
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 commands, 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 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.
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 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 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.
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 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.
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.
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 $Config{vms_prefix} is
used instead.
oneliner (o)
echo (o)
perl trips up on "<foo>" thinking it's an input redirect. So we use
the native Write command instead. Besides, its faster.
quote_literal
escape_newlines
max_exec_len
256 characters.
init_linker (o)
eliminate_macros
Expands MM[KS]/Make macros in a text string, using the contents of
identically named elements of %$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 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.
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 directory 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.
