ExtUti..._Win32(3perl)

✨ NAME ✨

ExtUtils::MM_Win32 — the methods that override the UN*X behaviour inside ExtUtils::MakeMaker 💅

Okay so real talk, bestie, this is the ExtUtils::MM_Win32 page from section 3perl of the Perl manual, and it's literally just the Windows-flavoured glow-up of the Unix makefile maker. Let's get into it 🫶

---

🌸 SYNOPSIS 🌸

use ExtUtils::MM_Win32; # Done internally by ExtUtils::MakeMaker if needed

Not that you'd ever load this yourself, bestie — ExtUtils::MakeMaker pulls it in behind the scenes whenever it needs it. It's giving backstage crew, not main character. 🙈

---

💖 DESCRIPTION 💖

Wanna know what all these methods actually do? Go read ExtUtils::MM_Unix — that's where the actual documentation lives, no cap.

The thing about this package is that it overrides the implementation of those methods, not the semantics. Same vibes, same meanings, different plumbing. It's literally just a Windows-shaped remix. 🎀

🦋 Overridden methods 🦋

dlsyms</p>, xs_dlsyms_ext</p>

On Win32, this one is .def. That's it, that's the whole vibe. 💀

replace_manpage_separator</p>

Swaps out the path separator and puts a . in its place. Periodt.

maybe_command</p>

Windows does not have anything as chill as an executable bit, so instead we go snooping through the file extension to figure out if something might be a command. 👀

The PATHEXT env variable gets used to build the list of extensions that could mean "this is a command". And if PATHEXT isn't giving, then the defaults kick in: .com, .exe, .bat and .cmd.

init_DIRFILESEP</p>

Uses \ for Windows — except for "gmake", where it's /. Two icons, both correct. ✨

init_tools</p>

Swaps some of the slower, portable commands out for Windows-specific ones. Speed upgrade, slay.

init_others</p>

Overrides the default link and compile tools.

LDLOADLIBS's default gets changed to $Config{libs}.

And adjustments are made for Borland's quirks, because Borland needs -L to come first. Quirky queen. 💅

init_platform</p>

Adds MM_Win32_VERSION. New constant just dropped. 🔥

platform_constants</p>

(Just vibing here in the list, bestie — no extra notes on this one. 🙈)

specify_shell</p>

Sets SHELL to $ENV{COMSPEC} only if the make is type 'gmake'. Conditional queen.

constants</p>

Adds MAXLINELENGTH for dmake before all the constants get output. Order matters, iykyk.

dep_constants</p>

Builds the dependencies in a way that nmake can actually work with. nmake needs extra love, we provide it. 🫶

special_targets</p>

Adds the .USESHELL target for dmake.

static_lib_pure_cmd</p>

Defines how to run the archive utility.

dynamic_lib</p>

The methods overridden here are not dynamic_lib itself — it's the utility ones that do the OS-specific work. Don't get it twisted. 😭

extra_clean_files</p>

Cleans out some extra dll.{base,exp} files which gcc might have generated. Otherwise (and if those aren't a thing), it takes out all *.pdb files. Landfill duty, but make it thorough. 🧚

init_linker</p>

(Another quiet one in the list — no extra tea spilled here. ✨)

perl_script</p>

Checks for the perl program under several common perl extensions. Does it go by perl? Does it go by perl.exe? Who's to say. (We check. We check so many.) 🔍

quote_dep</p>

(Yes bestie, it's in the list. That's the whole update on this one. 💜)

xs_obj_opt</p>

Overridden to fixup the -o flags for MSVC. Little cleanup, big difference.

pasthru</p>

All we send through is -nologo to nmake, purely to stop it from printing its damned banner. That's the entire assignment. 😤

arch_check</p> (override)

Normalizes all arguments so comparisons are consistent. Same energy, same shape, every time. 🌈

oneliner</p>

These are based on what command.com does on Win98. They may be wrong for other Windows shells — I don't know. Honest king behavior, fr fr. 💀

cd</p>

dmake can handle Unix-style cd'ing, but nmake (at least 1.5) cannot. It wants this and only this:

cd dir1\dir2
command
another_command
cd ..\..

Look at it. Going down, doing the work, coming back up. The way that it just... walks in and out. 🚶‍♀️

max_exec_len</p>

nmake 1.50 limits command length to 2048 characters. That's the ceiling, bestie, respect the ceiling.

os_flavor</p>

Windows is Win32. Short, sweet, factual. ⭐

dbgoutflag</p>

Returns a CC flag that tells the CC to emit a separate debugging symbol file when compiling an object file.

cflags</p>

Defines the PERLDLL symbol if we're configured for static building — because all code destined for the perl5xx.dll must be compiled with the PERLDLL symbol defined. Rules are rules. 👑

make_type</p>

Returns a suitable string describing the type of makefile being written. Just a lil descriptor, as a treat. 🍓

💖 That's the whole page, bestie — every method, every quirk, nothing skipped, no cap.
