# NAME

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 dir1\dir2
          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.
