=head1 SYNOPSIS
-These are instructions for building Perl under Windows 9x/NT/2000/XP
-on the Intel x86 and Itanium architectures.
+These are instructions for building Perl under Windows 2000 and later.
=head1 DESCRIPTION
particular, you can safely ignore any information that talks about
"Configure".
-You may also want to look at two other options for building
-a perl that will work on Windows NT: the README.cygwin and
-README.os2 files, each of which give a different set of rules to
-build a Perl that will work on Win32 platforms. Those two methods
-will probably enable you to build a more Unix-compatible perl, but
-you will also need to download and use various other build-time and
-run-time support software described in those files.
+You may also want to look at one other option for building a perl that
+will work on Windows: the README.cygwin file, which give a different
+set of rules to build a perl for Windows. This method will probably
+enable you to build a more Unix-compatible perl, but you will also
+need to download and use various other build-time and run-time support
+software described in that file.
This set of instructions is meant to describe a so-called "native"
-port of Perl to Win32 platforms. This includes both 32-bit and
+port of Perl to the Windows platform. This includes both 32-bit and
64-bit Windows operating systems. The resulting Perl requires no
additional software to run (other than what came with your operating
system). Currently, this port is capable of using one of the
following compilers on the Intel x86 architecture:
- Borland C++ version 5.02 or later
- Microsoft Visual C++ version 4.2 or later
- Mingw32 with GCC version 2.95.2 or better
+ Borland C++ version 5.02 or later
+ Microsoft Visual C++ version 6.0 or later (*)
+ Gcc by mingw.org gcc version 3.2 or later
+ Gcc by mingw-w64.sf.net gcc version 4.4.3 or later
-The last of these is a high quality freeware compiler. Support
-for it is still experimental. (Older versions of GCC are known
-not to work.)
+(*) NOTE: Support for Visual C++ 2010 is not yet complete. This latest
+version of VC++ introduces some new C<errno.h> constants which conflict
+with Perl's current setting of them to match the corresponding WSAE*
+constants' values. Until this issue is resolved you will see several test
+failures (in F<cpan/autodie/t/flock.t>, F<dist/IO/t/io_multihomed.t >,
+F<dist/Net-Ping/t/450_service.t> and F<dist/Net-Ping/t/510_ping_udp.t>)
+and experience other problems in code involving sockets.
-This port can also be built on the Intel IA64 using:

+The Borland C++ and Microsoft Visual C++ compilers are also now being given
+away free. The Borland compiler is available as "Borland C++ Compiler Free
+Command Line Tools" and is the same compiler that ships with the full
+"Borland C++ Builder" product. The Microsoft compiler is available as
+"Visual C++ Toolkit 2003" or "Visual C++ 2005/2008/2010 Express Edition" (and
+also as part of the ".NET Framework SDK") and is the same compiler that ships
+with "Visual C++ .NET 2003 Professional" or "Visual C++ 2005/2008/2010
+Professional" respectively.

+This port can also be built on IA64/AMD64 using:

+
+The Windows SDK can be downloaded from L<http://www.microsoft.com/>.
+The MinGW64 compiler is available at L<http://sourceforge.net/projects/mingw-w64>.
+The latter is actually a cross-compiler targeting Win64. There's also a trimmed
+down compiler (no java, or gfortran) suitable for building perl available at:
+L<http://strawberryperl.com/package/kmx/64_gcctoolchain/mingw64-w64-20100123-kmx-v2.zip>
-The MS Platform SDK can be downloaded from http://www.microsoft.com/.
+NOTE: If you're using a 32-bit compiler to build perl on a 64-bit Windows
+operating system, then you should set the WIN64 environment variable to "undef".
+Also, the trimmed down compiler only passes tests when USE_ITHREADS *= define
+(as opposed to undef) and when the CFG *= Debug line is commented out.
This port fully supports MakeMaker (the set of modules that
is used to build extensions to perl). Therefore, you should be
able to build and install most extensions found in the CPAN sites.

+Note that it is generally not a good idea to try to build a perl with
+INST_DRV and INST_TOP set to a path that already exists from a previous

+
+If building with the cross-compiler provided by
+mingw-w64.sourceforge.net you'll need to uncomment the line that sets
+GCCCROSS in the makefile.mk. Do this only if it's the cross-compiler - ie
+only if the bin folder doesn't contain a gcc.exe. (The cross-compiler
+does not provide a gcc.exe, g++.exe, ar.exe, etc. Instead, all of these
+executables are prefixed with 'x86_64-w64-mingw32-'.)

and is valid.

done is also somewhat less powerful than the approach suggested above.
-=item Win32 Specific Extensions
-
-A number of extensions specific to the Win32 platform are available
-from CPAN. You may find that many of these extensions are meant to
-be used under the Activeware port of Perl, which used to be the only
-native port for the Win32 platform. Since the Activeware port does not
-have adequate support for Perl's extension building tools, these
-extensions typically do not support those tools either and, therefore,
-cannot be built using the generic steps shown in the previous section.
-
-To ensure smooth transitioning of existing code that uses the
-ActiveState port, there is a bundle of Win32 extensions that contains
-all of the ActiveState extensions and most other Win32 extensions from
-CPAN in source form, along with many added bugfixes, and with MakeMaker
-support. This bundle is available at:
-
- http://www.cpan.org/authors/id/GSAR/libwin32-0.18.zip
-
-See the README in that distribution for building and installation
-instructions. Look for later versions that may be available at the
-same location.

=item Notes on 64-bit Windows
Windows .NET Server supports the LLP64 data model on the Intel Itanium
of Perl on a 64-bit system. Given this, why would one want to build
a 64-bit build of Perl? Here are some reasons why you would bother:

Perl scripts on UNIX use the "#!" (a.k.a "shebang") line to

-commands "assoc" and "ftype" that come standard with Windows NT

A script called "runperl.bat" is available that can be copied
to any filename (along with the .bat suffix). For example,
if you call it "foo.bat", it will run the file "foo" when it is

by typing the name (without the extension), this effectively

With this method, "foo.bat" can even be in a different location
"runperl". Explain the observed behavior, or lack thereof. :)
