.SH "NAME"
perlwin32 \- Perl under Windows
.SH "SYNOPSIS"
.IX Header "SYNOPSIS"
These are instructions for building Perl under Windows 9x/NT/2000/XP
on the Intel x86 and Itanium architectures.
.SH "DESCRIPTION"
.IX Header "DESCRIPTION"
Before you start, you should glance through the \s-1README\s0 file
found in the top-level directory to which the Perl distribution
was extracted.  Make sure you read and understand the terms under
which this software is being distributed.
.PP
Also make sure you read \*(L"\s-1BUGS\s0 \s-1AND\s0 \s-1CAVEATS\s0\*(R" below for the
known limitations of this port.
.PP
The \s-1INSTALL\s0 file in the perl top-level has much information that is
only relevant to people building Perl on Unix-like systems.  In
particular, you can safely ignore any information that talks about
\&\*(L"Configure\*(R".
.PP
You may also want to look at two other options for building
a perl that will work on Windows \s-1NT:\s0  the \s-1README\s0.cygwin and
\&\s-1README\s0.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.
.PP
This set of instructions is meant to describe a so-called \*(L"native\*(R"
port of Perl to Win32 platforms.  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:
.PP
.Vb 3
\&      Borland C++           version 5.02 or later
\&      Microsoft Visual C++  version 2.0 or later
\&      MinGW with gcc        gcc version 2.95.2 or later
.Ve
.PP
The last of these is a high quality freeware compiler.  Use version
3.2.x or later for the best results with this compiler.
.PP
The Borland \*(C+ and Microsoft Visual \*(C+ compilers are also now being given
away free.  The Borland compiler is available as \*(L"Borland \*(C+ Compiler Free
Command Line Tools\*(R" and is the same compiler that ships with the full
\&\*(L"Borland \*(C+ Builder\*(R" product.  The Microsoft compiler is available as
\&\*(L"Visual \*(C+ Toolkit 2003\*(R" or \*(L"Visual \*(C+ 2005/2008 Express Edition\*(R" (and also
as part of the \*(L".NET Framework \s-1SDK\s0\*(R") and is the same compiler that ships with
\&\*(L"Visual \*(C+ .NET 2003 Professional\*(R" or \*(L"Visual \*(C+ 2005/2008 Professional\*(R"
respectively.
.PP
This port can also be built on the Intel \s-1IA64\s0 using:
.PP
.Vb 1
\&      Microsoft Platform SDK    Nov 2001 (64\-bit compiler and tools)
.Ve
.PP
The \s-1MS\s0 Platform \s-1SDK\s0 can be downloaded from http://www.microsoft.com/.
.PP
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 \s-1CPAN\s0 sites.
See \*(L"Usage Hints for Perl on Win32\*(R" below for general hints about this.
.Sh "Setting Up Perl on Win32"
.IX Subsection "Setting Up Perl on Win32"
.IP "Make" 4
.IX Item "Make"
You need a \*(L"make\*(R" program to build the sources.  If you are using
Visual \*(C+ or the Platform \s-1SDK\s0 tools under Windows \s-1NT/2000/XP\s0, nmake
will work.  All other builds need dmake.
.Sp
dmake is a freely available make that has very nice macro features
and parallelability.
.Sp
A port of dmake for Windows is available from:
.Sp
.Vb 1
\&    http://search.cpan.org/dist/dmake/
.Ve
.Sp
Fetch and install dmake somewhere on your path.
.Sp
There exists a minor coexistence problem with dmake and Borland \*(C+
compilers.  Namely, if a distribution has C files named with mixed
case letters, they will be compiled into appropriate .obj\-files named
with all lowercase letters, and every time dmake is invoked
to bring files up to date, it will try to recompile such files again.
For example, Tk distribution has a lot of such files, resulting in
needless recompiles every time dmake is invoked.  To avoid this, you
may use the script \*(L"sync_ext.pl\*(R" after a successful build.  It is
available in the win32 subdirectory of the Perl source distribution.
.IP "Command Shell" 4
.IX Item "Command Shell"
Use the default \*(L"cmd\*(R" shell that comes with \s-1NT\s0.  Some versions of the
popular 4DOS/NT shell have incompatibilities that may cause you trouble.
If the build fails under that shell, try building again with the cmd
shell.
.Sp
The nmake Makefile also has known incompatibilities with the
\&\*(L"command.com\*(R" shell that comes with Windows 9x.  You will need to
use dmake and makefile.mk to build under Windows 9x.
.Sp
The surest way to build it is on Windows \s-1NT/2000/XP\s0, using the cmd shell.
.Sp
Make sure the path to the build directory does not contain spaces.  The
build usually works in this circumstance, but some tests will fail.
.IP "Borland \*(C+" 4
.IX Item "Borland "
If you are using the Borland compiler, you will need dmake.
(The make that Borland supplies is seriously crippled and will not
work for MakeMaker builds.)
.Sp
See \*(L"Make\*(R" above.
.IP "Microsoft Visual \*(C+" 4
.IX Item "Microsoft Visual "
The nmake that comes with Visual \*(C+ will suffice for building.
You will need to run the \s-1VCVARS32\s0.BAT file, usually found somewhere
like C:\eMSDEV4.2\eBIN or C:\eProgram Files\eMicrosoft Visual Studio\eVC98\eBin.
This will set your build environment.
.Sp
You can also use dmake to build using Visual \*(C+; provided, however,
you set \s-1OSRELEASE\s0 to \*(L"microsft\*(R" (or whatever the directory name
under which the Visual C dmake configuration lives) in your environment
and edit win32/config.vc to change \*(L"make=nmake\*(R" into \*(L"make=dmake\*(R".  The
latter step is only essential if you want to use dmake as your default
make for building extensions using MakeMaker.
.IP "Microsoft Visual \*(C+ 2008 Express Edition Beta 2" 4
.IX Item "Microsoft Visual  2008 Express Edition Beta 2"
This free version of Visual \*(C+ 2008 Professional contains the same compiler
and linker that ship with the full version, and also contains everything
necessary to build Perl, rather than requiring a separate download of the
Platform \s-1SDK\s0 like previous versions did.
.Sp
The Beta 2 package is currently available from
.Sp
http://msdn2.microsoft.com/en\-us/express/future/default.aspx
http://msdn2.microsoft.com/en\-gb/express/future/default.aspx
.Sp
The final release version will probably be found by searching in the Download
Center at http://www.microsoft.com/downloads/search.aspx?displaylang=en in due
course.
