-Quick Start Guide

------------------

-

-1.  Install Microsoft Visual Studio 2015, any edition.

-2.  Install Subversion, and make sure 'svn.exe' is on your PATH.

-3.  Run "build.bat -e" to build Python in 32-bit Release configuration.

-4.  (Optional, but recommended) Run the test suite with "rt.bat -q".

-

-

-Building Python using Microsoft Visual C++

-------------------------------------------

-

-This directory is used to build CPython for Microsoft Windows NT version

-6.0 or higher (Windows Vista, Windows Server 2008, or later) on 32 and 64

-bit platforms.  Using this directory requires an installation of

-Microsoft Visual C++ 2015 (MSVC 14.0) of any edition.  The specific

-requirements are as follows:

-

-Visual Studio Express 2015 for Desktop

-Visual Studio Professional 2015

-    Either edition is sufficient for building all configurations except

-    for Profile Guided Optimization.

-    The Python build solution pcbuild.sln makes use of Solution Folders,

-    which this edition does not support.  Any time pcbuild.sln is opened

-    or reloaded by Visual Studio, a warning about Solution Folders will

-    be displayed, which can be safely dismissed with no impact on your

-    ability to build Python.

-    Required for building 64-bit Debug and Release configuration builds

-Visual Studio Premium 2015

-    Required for building Release configuration builds that make use of

-    Profile Guided Optimization (PGO), on either platform.

-

-All you need to do to build is open the solution "pcbuild.sln" in Visual

-Studio, select the desired combination of configuration and platform,

-then build with "Build Solution".  You can also build from the command

-line using the "build.bat" script in this directory; see below for

-details.  The solution is configured to build the projects in the correct

-order.

-

-The solution currently supports two platforms.  The Win32 platform is

-used to build standard x86-compatible 32-bit binaries, output into the

-win32 sub-directory.  The x64 platform is used for building 64-bit AMD64

-(aka x86_64 or EM64T) binaries, output into the amd64 sub-directory.

-The Itanium (IA-64) platform is no longer supported.

-

-Four configuration options are supported by the solution:

-Debug

-    Used to build Python with extra debugging capabilities, equivalent

-    to using ./configure --with-pydebug on UNIX.  All binaries built

-    using this configuration have "_d" added to their name:

-    python37_d.dll, python_d.exe, parser_d.pyd, and so on.  Both the

-    build and rt (run test) batch files in this directory accept a -d

-    option for debug builds.  If you are building Python to help with

-    development of CPython, you will most likely use this configuration.

-PGInstrument, PGUpdate

-    Used to build Python in Release configuration using PGO, which

-    requires Premium Edition of Visual Studio.  See the "Profile

-    Guided Optimization" section below for more information.  Build

-    output from each of these configurations lands in its own

-    sub-directory of this directory.  The official Python releases may

-    be built using these configurations.

-Release

-    Used to build Python as it is meant to be used in production

-    settings, though without PGO.

-

-

-Building Python using the build.bat script

-----------------------------------------------

-

-In this directory you can find build.bat, a script designed to make

-building Python on Windows simpler.  This script will use the env.bat

-script to detect one of Visual Studio 2015, 2013, 2012, or 2010, any of

-which may be used to build Python, though only Visual Studio 2015 is

-officially supported.

-

-By default, build.bat will build Python in Release configuration for

-the 32-bit Win32 platform.  It accepts several arguments to change

-this behavior, try `build.bat -h` to learn more.

-

-

-C Runtime

----------

-

-Visual Studio 2015 uses version 14 of the C runtime (MSVCRT14).  The

-executables no longer use the "Side by Side" assemblies used in previous

-versions of the compiler.  This simplifies distribution of applications.

-

-The run time libraries are available under the VC/Redist folder of your

-Visual Studio distribution. For more info, see the Readme in the

-VC/Redist folder.

-

-

-Sub-Projects

-------------

-

-The CPython project is split up into several smaller sub-projects which

-are managed by the pcbuild.sln solution file.  Each sub-project is

-represented by a .vcxproj and a .vcxproj.filters file starting with the

-name of the sub-project.  These sub-projects fall into a few general

-categories:

-

-The following sub-projects represent the bare minimum required to build

-a functioning CPython interpreter.  If nothing else builds but these,

-you'll have a very limited but usable python.exe:

-pythoncore

-    .dll and .lib

-python

-    .exe

-

-These sub-projects provide extra executables that are useful for running

-CPython in different ways:

-pythonw

-    pythonw.exe, a variant of python.exe that doesn't open a Command

-    Prompt window

-pylauncher

-    py.exe, the Python Launcher for Windows, see

-        http://docs.python.org/3/using/windows.html#launcher

-pywlauncher

-    pyw.exe, a variant of py.exe that doesn't open a Command Prompt

-    window

-_testembed

-    _testembed.exe, a small program that embeds Python for testing

-    purposes, used by test_capi.py

-

-These are miscellaneous sub-projects that don't really fit the other

-categories:

-_freeze_importlib

-    _freeze_importlib.exe, used to regenerate Python\importlib.h after

-    changes have been made to Lib\importlib\_bootstrap.py

-python3dll

-    python3.dll, the PEP 384 Stable ABI dll

-xxlimited

-    builds an example module that makes use of the PEP 384 Stable ABI,

-    see Modules\xxlimited.c

-

-The following sub-projects are for individual modules of the standard

-library which are implemented in C; each one builds a DLL (renamed to

-.pyd) of the same name as the project:

-_ctypes

-_ctypes_test

-_decimal

-_elementtree

-_hashlib

-_msi

-_multiprocessing

-_overlapped

-_socket

-_testcapi

-_testbuffer

-_testimportmultiple

-pyexpat

-select

-unicodedata

-winsound

-

-The following Python-controlled sub-projects wrap external projects.

-Note that these external libraries are not necessary for a working

-interpreter, but they do implement several major features.  See the

-"Getting External Sources" section below for additional information

-about getting the source for building these libraries.  The sub-projects

-are:

-_bz2

-    Python wrapper for version 1.0.6 of the libbzip2 compression library

-    Homepage:

-        http://www.bzip.org/

-_lzma

-    Python wrapper for the liblzma compression library, using pre-built

-    binaries of XZ Utils version 5.0.5

-    Homepage:

-        http://tukaani.org/xz/

-_ssl

-    Python wrapper for version 1.0.2k of the OpenSSL secure sockets

-    library, which is built by ssl.vcxproj

-    Homepage:

-        http://www.openssl.org/

-

-    Building OpenSSL requires nasm.exe (the Netwide Assembler), version

-    2.10 or newer from

-        http://www.nasm.us/

-    to be somewhere on your PATH.  More recent versions of OpenSSL may

-    need a later version of NASM. If OpenSSL's self tests don't pass,

-    you should first try to update NASM and do a full rebuild of

-    OpenSSL.  If you use the PCbuild\get_externals.bat method

-    for getting sources, it also downloads a version of NASM which the

-    libeay/ssleay sub-projects use.

-

-    The libeay/ssleay sub-projects expect your OpenSSL sources to have

-    already been configured and be ready to build.  If you get your sources

-    from svn.python.org as suggested in the "Getting External Sources"

-    section below, the OpenSSL source will already be ready to go.  If

-    you want to build a different version, you will need to run

-

-       PCbuild\prepare_ssl.py path\to\openssl-source-dir

-

-    That script will prepare your OpenSSL sources in the same way that

-    those available on svn.python.org have been prepared.  Note that

-    Perl must be installed and available on your PATH to configure

-    OpenSSL.  ActivePerl is recommended and is available from

-        http://www.activestate.com/activeperl/

-

-    The libeay and ssleay sub-projects will build the modules of OpenSSL

-    required by _ssl and _hashlib and may need to be manually updated when

-    upgrading to a newer version of OpenSSL or when adding new

-    functionality to _ssl or _hashlib. They will not clean up their output

-    with the normal Clean target; CleanAll should be used instead.

-_sqlite3

-    Wraps SQLite 3.14.2.0, which is itself built by sqlite3.vcxproj

-    Homepage:

-        http://www.sqlite.org/

-_tkinter

-    Wraps version 8.6.6 of the Tk windowing system.

-    Homepage:

-        http://www.tcl.tk/

-

-    Tkinter's dependencies are built by the tcl.vcxproj and tk.vcxproj

-    projects.  The tix.vcxproj project also builds the Tix extended

-    widget set for use with Tkinter.

-

-    Those three projects install their respective components in a

-    directory alongside the source directories called "tcltk" on

-    Win32 and "tcltk64" on x64.  They also copy the Tcl and Tk DLLs

-    into the current output directory, which should ensure that Tkinter

-    is able to load Tcl/Tk without having to change your PATH.

-

-    The tcl, tk, and tix sub-projects do not clean their builds with

-    the normal Clean target; if you need to rebuild, you should use the

-    CleanAll target or manually delete their builds.

-

-

-Getting External Sources

-------------------------

-

-The last category of sub-projects listed 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.  However, a simple script is provided to make this as

-painless as possible, called "get_externals.bat" and located in this

-directory.  This script extracts all the external sub-projects from

-    http://svn.python.org/projects/external

-via Subversion (so you'll need svn.exe on your PATH) and places them

-in ..\externals (relative to this directory).

-

-It is also possible to download sources from each project's homepage,

-though you may have to change folder names or pass the names to MSBuild

-as the values of certain properties in order for the build solution to

-find them.  This is an advanced topic and not necessarily fully

-supported.

-

-The get_externals.bat script is called automatically by build.bat when

-you pass the '-e' option to it.

-

-

-Profile Guided Optimization

----------------------------

-

-The solution has two configurations for PGO. The PGInstrument

-configuration must be built first. The PGInstrument binaries are linked

-against a profiling library and contain extra debug information. The

-PGUpdate configuration takes the profiling data and generates optimized

-binaries.

-

-The build_pgo.bat script automates the creation of optimized binaries.

-It creates the PGI files, runs the unit test suite or PyBench with the

-PGI python, and finally creates the optimized files.

-

-See

-    http://msdn.microsoft.com/en-us/library/e7k32f4k(VS.140).aspx

-for more on this topic.

-

-

-Static library

---------------

-

-The solution has no configuration for static libraries. However it is

-easy to build a static library instead of a DLL. You simply have to set

-the "Configuration Type" to "Static Library (.lib)" and alter the

-preprocessor macro "Py_ENABLE_SHARED" to "Py_NO_ENABLE_SHARED". You may

-also have to change the "Runtime Library" from "Multi-threaded DLL

-(/MD)" to "Multi-threaded (/MT)".

-

-

-Visual Studio properties

-------------------------

-

-The PCbuild solution makes use of Visual Studio property files (*.props)

-to simplify each project. The properties can be viewed in the Property

-Manager (View -> Other Windows -> Property Manager) but should be

-carefully modified by hand.

-

-The property files used are:

- * python (versions, directories and build names)

- * pyproject (base settings for all projects)

- * openssl (used by libeay and ssleay projects)

- * tcltk (used by _tkinter, tcl, tk and tix projects)

-

-The pyproject property file defines all of the build settings for each

-project, with some projects overriding certain specific values. The GUI

-doesn't always reflect the correct settings and may confuse the user

-with false information, especially for settings that automatically adapt

-for diffirent configurations.
