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.)
|
|
|
|
All you need to do is open the workspace "pcbuild.sln" in Visual Studio,
|
|
select the desired combination of configuration and platform and eventually
|
|
build the solution. Unless you are going to debug a problem in the core or
|
|
you are going to create an optimized build you want to select "Release" as
|
|
configuration.
|
|
|
|
The PCbuild directory is compatible with all versions of Visual Studio from
|
|
VS C++ Express Edition over the standard edition up to the professional
|
|
edition. However the express edition does support features like solution
|
|
folders or profile guided optimization (PGO). The missing bits and pieces
|
|
won't stop you from building Python.
|
|
|
|
The solution is configured to build the projects in the correct order. "Build
|
|
Solution" or F7 takes care of dependencies except for x64 builds. To make
|
|
cross compiling x64 builds on a 32bit OS possible the x64 builds require a
|
|
32bit version of Python.
|
|
|
|
NOTE:
|
|
You probably don't want to build most of the other subprojects, unless
|
|
you're building an entire Python distribution from scratch, or
|
|
specifically making changes to the subsystems they implement, or are
|
|
running a Python core buildbot test slave; see SUBPROJECTS below)
|
|
|
|
When using the Debug setting, the output files have a _d added to
|
|
their name: python30_d.dll, python_d.exe, parser_d.pyd, and so on. Both
|
|
the build and rt batch files accept a -d option for debug builds.
|
|
|
|
The 32bit builds end up in the solution folder PCbuild while the x64 builds
|
|
land in the amd64 subfolder. The PGI and PGO builds for profile guided
|
|
optimization end up in their own folders, too.
|
|
|
|
Legacy support
|
|
--------------
|
|
|
|
You can find build directories for older versions of Visual Studio and
|
|
Visual C++ in the PC directory. The legacy build directories are no longer
|
|
actively maintained and may not work out of the box.
|
|
|
|
PC/VC6/
|
|
Visual C++ 6.0
|
|
PC/VS7.1/
|
|
Visual Studio 2003 (7.1)
|
|
PCbuild8/
|
|
Visual Studio 2005 (8.0)
|
|
|
|
|
|
C RUNTIME
|
|
---------
|
|
|
|
Visual Studio 2008 uses version 9 of the C runtime (MSVCRT9). The executables
|
|
are linked to a CRT "side by side" assembly which must be present on the target
|
|
machine. This is avalible under the VC/Redist folder of your visual studio
|
|
distribution. On XP and later operating systems that support
|
|
side-by-side assemblies it is not enough to have the msvcrt80.dll present,
|
|
it has to be there as a whole assembly, that is, a folder with the .dll
|
|
and a .manifest. Also, a check is made for the correct version.
|
|
Therefore, one should distribute this assembly with the dlls, and keep
|
|
it in the same directory. For compatibility with older systems, one should
|
|
also set the PATH to this directory so that the dll can be found.
|
|
For more info, see the Readme in the VC/Redist folder.
|
|
|
|
SUBPROJECTS
|
|
-----------
|
|
These subprojects should build out of the box. Subprojects other than the
|
|
main ones (pythoncore, python, pythonw) generally build a DLL (renamed to
|
|
.pyd) from a specific module so that users don't have to load the code
|
|
supporting that module unless they import the module.
|
|
|
|
pythoncore
|
|
.dll and .lib
|
|
python
|
|
.exe
|
|
pythonw
|
|
pythonw.exe, a variant of python.exe that doesn't pop up a DOS box
|
|
_socket
|
|
socketmodule.c
|
|
_testcapi
|
|
tests of the Python C API, run via Lib/test/test_capi.py, and
|
|
implemented by module Modules/_testcapimodule.c
|
|
pyexpat
|
|
Python wrapper for accelerated XML parsing, which incorporates stable
|
|
code from the Expat project: http://sourceforge.net/projects/expat/
|
|
select
|
|
selectmodule.c
|
|
unicodedata
|
|
large tables of Unicode data
|
|
winsound
|
|
play sounds (typically .wav files) under Windows
|
|
|
|
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\.
|
|
|
|
_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
|
|
---------------
|
|
Use "Start -> All Programs -> Microsoft Visual Studio 2008
|

bz2
|
|
Python wrapper for the libbz2 compression library. Homepage
|
|
http://sources.redhat.com/bzip2/
|
|
Download the source from the python.org copy into the dist
|
|
directory:
|
|
|
|
svn export http://svn.python.org/projects/external/bzip2-1.0.3
|
|
|
|
A custom pre-link step in the bz2 project settings should manage to
|
|
build bzip2-1.0.3\libbz2.lib by magic before bz2.pyd (or bz2_d.pyd) is
|
|
linked in PCbuild\.
|
|
However, the bz2 project is not smart enough to remove anything under
|
|
bzip2-1.0.3\ when you do a clean, so if you want to rebuild bzip2.lib
|
|
you need to clean up bzip2-1.0.3\ by hand.
|
|
|
|
All of this managed to build libbz2.lib in
|
|
bzip2-1.0.3\$platform-$configuration\, which the Python project links in.
|
|
|
|
|
|
_bsddb
|
|
To use the version of bsddb that Python is built with by default, invoke
|
|
(in the dist directory)
|
|
|
|
svn export http://svn.python.org/projects/external/db-4.4.20
|
|
|
|
Next open the solution file db-4.4.20\build_win32\Berkeley_DB.sln with
|
|
Visual Studio and convert the projects to the new format. VS 2008
|
|
builds the necessary libraries in a pre-link step of _bsddb. You
|
|
have to add "$(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.
|
|
|
|
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.
|
|
|
|
_sqlite3
|
|
Python wrapper for SQLite library.
|
|
|
|
Get the source code through
|
|
|
|
svn export http://svn.python.org/projects/external/sqlite-source-3.3.4
|
|
|
|
To use the extension module in a Python build tree, copy sqlite3.dll into
|
|
the PCbuild folder. The source directory in svn also contains a .def file
|
|
from the binary release of sqlite3.
|
|
|
|
_ssl
|
|
Python wrapper for the secure sockets library.
|
|
|
|
Get the source code through
|
|
|
|
svn export http://svn.python.org/projects/external/openssl-0.9.8g
|
|
|
|
Alternatively, get the latest version from http://www.openssl.org.
|
|
You can (theoretically) use any version of OpenSSL you like - the
|
|
build process will automatically select the latest version.
|
|
|
|
You must install the NASM assembler from
|
|
http://www.kernel.org/pub/software/devel/nasm/binaries/win32/
|
|
for x86 builds. Put nasmw.exe anywhere in your PATH.
|
|
|
|
You can also install ActivePerl from
|
|
http://www.activestate.com/Products/ActivePerl/
|
|
if you like to use the official sources instead of the files from
|
|
python's subversion repository. The svn version contains pre-build
|
|
makefiles and assembly files.
|
|
|
|
The build process makes sure that no patented algorithms are included.
|
|
For now RC5, MDC2 and IDEA are excluded from the build. You may have
|
|
to manually remove $(OBJ_D)\i_*.obj from ms\nt.mak if the build process
|
|
complains about missing files or forbidden IDEA. Again the files provided
|
|
in the subversion repository are already fixed.
|
|
|
|
The MSVC project simply invokes PCBuild/build_ssl.py to perform
|
|
the build. This Python script locates and builds your OpenSSL
|
|
installation, then invokes a simple makefile to build the final .pyd.
|
|
|
|
build_ssl.py attempts to catch the most common errors (such as not
|
|
being able to find OpenSSL sources, or not being able to find a Perl
|
|
that works with OpenSSL) and give a reasonable error message.
|
|
If you have a problem that doesn't seem to be handled correctly
|
|
(eg, you know you have ActivePerl but we can't find it), please take
|
|
a peek at build_ssl.py and suggest patches. Note that build_ssl.py
|
|
should be able to be run directly from the command-line.
|
|
|
|
build_ssl.py/MSVC isn't clever enough to clean OpenSSL - you must do
|
|
this by hand.
|
|
|
|
Building for Itanium
|
|
--------------------
|
|
|
|
NOTE:
|
|
Official support for Itanium builds have been dropped from the build. Please
|
|
contact us and provide patches if you are interested in Itanium builds.
|
|
|
|
The project files support a ReleaseItanium configuration which creates
|
|
Win64/Itanium binaries. For this to work, you need to install the Platform
|
|
SDK, in particular the 64-bit support. This includes an Itanium compiler
|
|
(future releases of the SDK likely include an AMD64 compiler as well).
|
|
In addition, you need the Visual Studio plugin for external C compilers,
|
|
from http://sf.net/projects/vsextcomp. The plugin will wrap cl.exe, to
|
|
locate the proper target compiler, and convert compiler options
|
|
accordingly. The project files require atleast version 0.9.
|
|
|
|
Building for AMD64
|
|
------------------
|
|
|
|
The build process for AMD64 / x64 is very similar to standard builds. You just
|
|
have to set x64 as platform. In addition, the HOST_PYTHON environment variable
|
|
must point to a Python interpreter (at least 2.4), to support cross-compilation.
|
|
|
|
Building Python Using the free MS Toolkit Compiler
|
|
--------------------------------------------------
|
|
|
|
Microsoft has withdrawn the free MS Toolkit Compiler, so this can no longer
|
|
be considered a supported option. Instead you can use the free VS C++ Express
|
|
Edition.
|
|
|
|
Profile Guided Optimization
|
|
---------------------------
|
|
|
|
The solution has two configurations for PGO. The PGInstrument
|
|
configuration must be build first. The PGInstrument binaries are
|
|
lniked 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.
|
|
|
|
http://msdn2.microsoft.com/en-us/library/e7k32f4k(VS.90).aspx
|
|
|
|
Static library
|
|
--------------
|
|
|
|
The solution has no configuration for static libraries. However it is easy
|
|
it 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 heavy use of Visual Studio property files
|
|
(*.vsprops). The properties can be viewed and altered in the Property
|
|
Manager (View -> Other Windows -> Property Manager).
|
|
|
|
* debug (debug macro: _DEBUG)
|
|
* pginstrument (PGO)
|
|
* pgupdate (PGO)
|
|
+-- pginstrument
|
|
* pyd (python extension, release build)
|
|
+-- release
|
|
+-- pyproject
|
|
* pyd_d (python extension, debug build)
|
|
+-- debug
|
|
+-- pyproject
|
|
* pyproject (base settings for all projects, user macros like PyDllName)
|
|
* release (release macro: NDEBUG)
|
|
* x64 (AMD64 / x64 platform specific settings)
|
|
|
|
The pyproject propertyfile defines _WIN32 and x64 defines _WIN64 and _M_X64
|
|
although the macros are set by the compiler, too. The GUI doesn't always know
|
|
about the macros and confuse the user with false information.
|
|
|
|
YOUR OWN EXTENSION DLLs
|
|
-----------------------
|
|
|
|
If you want to create your own extension module DLL, there's an example
|
|
with easy-to-follow instructions in ../PC/example/; read the file
|
|
readme.txt there first.
|
