ExtUtils::MM_Win32(3)

🎀 NAME 🎀

Okay bestie, this is ExtUtils::MM_Win32(3) — the User Contributed Perl Documentation for ExtUtils::MM_Win32: methods to override UN*X behaviour in ExtUtils::MakeMaker. 💖

---

✨ SYNOPSIS ✨

Literally all you need, bestie:

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

---

🦋 DESCRIPTION 🦋

Go see ExtUtils::MM_Unix for a documentation of the methods provided there. This package overrides the implementation of these methods, not the semantics. Same vibe, different plumbing, no cap. 💅

🌸 Overridden methods 🌸

Here's the whole roster of overrides, no skips — every method and every note from the page, bestie. ✨

• dlsyms
• xs_dlsyms_ext — On Win32, it's ".def".
• 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. Lowkey iconic. 🫶

• init_DIRFILESEP — Using \ for Windows, except for "gmake" where it is /.
• 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
• specify_shell — Set SHELL to $ENV{COMSPEC} only if make is type 'gmake'.
• constants — Add MAXLINELENGTH for dmake before all the constants are output.
• special_targets — Add .USESHELL target for dmake.
• static_lib_pure_cmd — Defines how to run the archive utility.
• dynamic_lib — Methods are overridden here: not dynamic_lib itself, but the utility ones that do the OS-specific work.
• 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.
• quote_dep
• xs_obj_opt — Override to fixup -o flags for MSVC.
• 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 dir1\dir2
command
another_command
cd ..\..

• max_exec_len — nmake 1.50 limits command length to 2048 characters.
• os_flavor — Windows is Win32.
• dbgoutflag — Returns a CC flag that tells the CC to emit a separate debugging symbol file when compiling an object file.
• 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.
• make_type — Returns a suitable string describing the type of makefile being written.
