ExtUtils::MM_Win32 - methods to override UN*X behaviour in ExtUtils::MakeMaker
SYNOPSIS
use ExtUtils::MM_Win32; # 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.
Overridden methods
dlsyms
replace_manpage_separator
Changes the path separator with .
maybe_command
Since Windows has nothing as simple as an executable bit, we check the file extension.
The PATHEXT env variable will be used to get a list of extensions that might indicate a command, otherwise .com, .exe, .bat and .cmd
will be used by default.
init_DIRFILESEP
Using for Windows.
init_tools
Override some of the slower, portable commands with Windows specific ones.
init_others
Override the default link and compile tools.
LDLOADLIBS's default is changed to $Config{libs}.
Adjustments are made for Borland's quirks needing -L to come first.
init_platform
Add MM_Win32_VERSION.
platform_constants
constants
Add MAXLINELENGTH for dmake before all the constants are output.
special_targets
Add .USESHELL target for dmake.
static_lib
Changes how to run the linker.
The rest is duplicate code from MM_Unix. Should move the linker code to its own method.
dynamic_lib
Complicated stuff for Win32 that I don't understand. :(
extra_clean_files
Clean out some extra dll.{base,exp} files which might be generated by gcc. Otherwise, take out all *.pdb files.
init_linker
perl_script
Checks for the perl program under several common perl extensions.
xs_o
This target is stubbed out. Not sure why.
pasthru
All we send is -nologo to nmake to prevent it from printing its damned banner.
arch_check (override)
Normalize all arguments for consistency of comparison.
oneliner
These are based on what command.com does on Win98. They may be wrong for other Windows shells, I don't know.
cd dmake can handle Unix style cd'ing but nmake (at least 1.5) cannot. It wants:
cd dir1dir2
command
another_command
cd ....
max_exec_len
nmake 1.50 limits command length to 2048 characters.
os_flavor
Windows is Win32.
cflags
Defines the PERLDLL symbol if we are configured for static building since all code destined for the perl5xx.dll must be compiled with
the PERLDLL symbol defined.

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.
pasthru (override)
VMS has $(MMSQUALIFIERS) which is a listing of all the original command line options. This is used in every invocation of make in the
VMS Makefile so PASTHRU should not be necessary. Using PASTHRU tends to blow commands past the 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 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 .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.
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.
static_lib (override)
Use VMS commands to manipulate object library.
extra_clean_files
Clean up some OS specific files. Plus the temp file used to shorten a lot of commands.
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)
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 $Config{vms_prefix} is used instead.
cd
oneliner
echo
perl trips up on "<foo>" thinking it's an input redirect. So we use the native Write command instead. Besides, its faster.
quote_literal
escape_newlines
max_exec_len
256 characters.
init_linker
catdir (override)
catfile (override)
Eliminate the macros in the output to the MMS/MMK file.
(File::Spec::VMS used to do this for us, but it's being removed)
eliminate_macros
Expands MM[KS]/Make macros in a text string, using the contents of identically named elements of %$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.
fixpath() 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 fixpath() 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.
