Update information pertaining to building external components, as well as notes on x64 builds. This file now accurately describes the build process as is; however, there's still a lot of room for improvement, especially with regards to how we build Tcl/Tk, Tix, and OpenSSL. Watch this space for further improvements.

Building Python using VC++ 9.0
------------------------------
This directory is used to build Python for Win32 platforms, e.g. Windows
2000, XP and Vista. It requires Microsoft Visual C++ 9.0
(a.k.a. Visual Studio .NET 2008).
(For other Windows platforms and compilers, see ../PC/readme.txt.)
This directory is used to build Python for Win32 and x64 platforms, e.g.
Windows 2000, XP, Vista and Windows Server 2008. In order to build 32-bit
debug and release executables, Microsoft Visual C++ 2008 Express Edition is
required at the very least. In order to build 64-bit debug and release
executables, Visual Studio 2008 Standard Edition is required at the very
least. In order to build all of the above, as well as generate release builds
that make use of Profile Guided Optimisation (PG0), Visual Studio 2008
Professional Edition is required at the very least. The official Python
releases are built with this version of Visual Studio.
For other Windows platforms and compilers, see ../PC/readme.txt.

The following subprojects will generally NOT build out of the box. They
wrap code Python doesn't control, and you'll need to download the base
packages first and unpack them into siblings of PCbuilds's parent
directory; for example, if your PCbuild is ..\dist\py3k\PCbuild\,
unpack into new subdirectories of ..\dist\.

_sqlite3
Wraps SQLite 3.3.4, which is currently built by sqlite3.vcproj (see below).
_tkinter
Python wrapper for the Tk windowing system. Requires building
Tcl/Tk first. Following are instructions for Tcl/Tk 8.4.16.
NOTE: The 64 build builds must land in tcltk64 instead of tcltk.
Get source
----------
In the dist directory, run
svn export http://svn.python.org/projects/external/tcl8.4.16
svn export http://svn.python.org/projects/external/tk8.4.16
svn export http://svn.python.org/projects/external/tix-8.4.0
Build with build_tkinter.py
---------------------------
The PCbuild directory contains a Python script which automates all
steps. Run the script in a Visual Studio 2008 command prompt with
python build_tkinter.py Win32
Use x64 instead of Win32 for the x64 platform.
NOTE: Tcl/Tk 8.4 doesn't compile for x64.
Build Tcl first

nmake -f python9.mak install
Wraps the Tk windowing system. Unlike _bsddb and _sqlite3, there's no
corresponding tcltk.vcproj-type project that builds Tcl/Tk from vcproj's
within our pcbuild.sln, which means this module expects to find a
pre-built Tcl/Tk in either ..\..\tcltk for 32-bit or ..\..\tcltk64 for
64-bit (relative to this directory). See below for instructions to build
Tcl/Tk.

_bsddb
To use the version of bsddb that Python is built with by default, invoke
(in the dist directory)
svn export http://svn.python.org/projects/external/db-4.4.20
Next open the solution file db-4.4.20\build_win32\Berkeley_DB.sln with
Visual Studio and convert the projects to the new format. VS 2008
builds the necessary libraries in a pre-link step of _bsddb. You
have to add "$(VCInstallDir)vcpackages" to the search path first
(Tools -> Options -> Projects and Solutions -> VC++ Directories,
Platform: Win32, Show directories for: Executable files).
The _bsddb subprojects depends only on the db_static project of
Berkeley DB. You have to choose either "Release", "Release AMD64", "Debug"
or "Debug AMD64" as configuration. For the AND64 builds, you need to
create the "x64" platform first (in Solution Platforms\Configuration
Manager...)
Alternatively, if you want to start with the original sources,
go to Sleepycat's download page:
http://www.sleepycat.com/downloads/releasehistorybdb.html
and download version 4.4.20.
With or without strong cryptography? You can choose either with or
without strong cryptography, as per the instructions below. By
default, Python is built and distributed WITHOUT strong crypto.
Unpack the sources; if you downloaded the non-crypto version, rename
the directory from db-4.4.20.NC to db-4.4.20.
Now apply any patches that apply to your version.
Open
db-4.4.20\docs\ref\build_win\intro.html
and follow the "Windows->Building Berkeley DB with Visual C++ .NET"
instructions for building the Sleepycat
software. Note that Berkeley_DB.dsw is in the build_win32 subdirectory.
Build the "db_static" project, for "Release" mode.
To run extensive tests, pass "-u bsddb" to regrtest.py. test_bsddb3.py
is then enabled. Running in verbose mode may be helpful.

Python wrapper for SQLite library.
Get the source code through
svn export http://svn.python.org/projects/external/sqlite-source-3.3.4

The subprojects above wrap external projects Python doesn't control, and as
such, a little more work is required in order to download the relevant source
files for each project before they can be built. The buildbots do this each
time they're built, so the easiest approach is to run either external.bat or
external-amd64.bat in the ..\Tools\buildbot directory from ..\, i.e.:
C:\..\svn.python.org\projects\python\trunk\PCbuild>cd ..
C:\..\svn.python.org\projects\python\trunk>Tools\buildbot\external.bat
This extracts all the external subprojects from http://svn.python.org/external
via Subversion (so you'll need an svn.exe on your PATH) and places them in
..\.. (relative to this directory). The external(-amd64).bat scripts will
also build a debug build of Tcl/Tk; there aren't any equivalent batch files
for building release versions of Tcl/Tk lying around in the Tools\buildbot
directory. If you need to build a release version of Tcl/Tk it isn't hard
though, take a look at the relevant external(-amd64).bat file and find the
two nmake lines, then call each one without the 'DEBUG=1' parameter, i.e.:
The external-amd64.bat file contains this for tcl:
nmake -f makefile.vc COMPILERFLAGS=-DWINVER=0x0500 DEBUG=1 MACHINE=AMD64 INSTALLDIR=..\..\tcltk64 clean all install
So for a release build, you'd call it as:
nmake -f makefile.vc COMPILERFLAGS=-DWINVER=0x0500 MACHINE=AMD64 INSTALLDIR=..\..\tcltk64 clean all install
XXX Should we compile with OPTS=threads?
XXX Our installer copies a lot of stuff out of the Tcl/Tk install
XXX directory. Is all of that really needed for Python use of Tcl/Tk?
This will be cleaned up in the future; ideally Tcl/Tk will be brought into our
pcbuild.sln as custom .vcproj files, just as we've recently done with the
_bsddb44.vcproj and sqlite3.vcproj files, which will remove the need for
Tcl/Tk to be built separately via a batch file.
XXX trent.nelson 02-Apr-08:
Having the external subprojects in ..\.. relative to this directory is a
bit of a nuisance when you're working on py3k and trunk in parallel and
your directory layout mimics that of Python's subversion layout, e.g.:
C:\..\svn.python.org\projects\python\trunk
C:\..\svn.python.org\projects\python\branches\py3k
C:\..\svn.python.org\projects\python\branches\release25-maint
I'd like to change things so that external subprojects are fetched from
..\external instead of ..\.., then provide some helper scripts or batch
files that would set up a new ..\external directory with svn checkouts of
the relevant branches in http://svn.python.org/projects/external/, or
alternatively, use junctions to link ..\external with a pre-existing
externals directory being used by another branch. i.e. if I'm usually
working on trunk (and have previously created trunk\external via the
provided batch file), and want to do some work on py3k, I'd set up a
junction as follows (using the directory structure above as an example):
C:\..\python\trunk\external <- already exists and has built versions
of the external subprojects
C:\..\python\branches\py3k>linkd.exe external ..\..\trunk\external
Link created at: external
Only a slight tweak would be needed to the buildbots such that bots
building trunk and py3k could make use of the same facility. (2.5.x
builds need to be kept separate as they're using Visual Studio 7.1.)
