Building Python using VC++ 7.1
|
|
-------------------------------------
|
|
This directory is used to build Python for Win32 platforms, e.g. Windows
|
|
95, 98 and NT. It requires Microsoft Visual C++ 7.1
|
|
(a.k.a. Visual Studio .NET 2003).
|
|
(For other Windows platforms and compilers, see ../PC/readme.txt.)
|
|
|
|
All you need to do is open the workspace "pcbuild.sln" in MSVC++, select
|
|
the Debug or Release setting (using "Solution Configuration" from
|
|
the "Standard" toolbar"), and build the projects.
|
|
|
|
The proper order to build subprojects:
|
|
|
|
1) pythoncore (this builds the main Python DLL and library files,
|
|
python30.{dll, lib} in Release mode)
|
|
|
|
2) python (this builds the main Python executable,
|
|
python.exe in Release mode)
|
|
|
|
3) the other subprojects, as desired or needed (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.
|
|
|
|
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\src\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 8.4.12.
|
|
|
|
Get source
|
|
----------
|
|
In the dist directory, run
|
|
svn export http://svn.python.org/projects/external/tcl8.4.12
|
|
svn export http://svn.python.org/projects/external/tk8.4.12
|
|
svn export http://svn.python.org/projects/external/tix-8.4.0
|
|
|
|
Build Tcl first (done here w/ MSVC 7.1 on Windows XP)
|
|
---------------
|
|
Use "Start -> All Programs -> Microsoft Visual Studio .NET 2003
|
|
-> Visual Studio .NET Tools -> Visual Studio .NET 2003 Command Prompt"
|
|
to get a shell window with the correct environment settings
|
|

|
|
nmake -f makefile.vc
|
|
nmake -f makefile.vc INSTALLDIR=..\..\tcltk install
|
|
|
|
XXX Should we compile with OPTS=threads?
|
|
|
|
Optional: run tests, via

|
|
cd dist\tix-8.4.0\win
|
|
nmake -f python.mak

|
|
|
|
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.
|
|
|
|
The build step shouldn't yield any warnings or errors, and should end
|
|
by displaying 6 blocks each terminated with
|
|
FC: no differences encountered
|
|
|
|
All of this managed to build bzip2-1.0.3\libbz2.lib, 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
|
|
|
|
|
|
Then open a VS.NET 2003 shell, and invoke:
|
|
|
|
devenv db-4.4.20\build_win32\Berkeley_DB.sln /build Release /project db_static
|
|
|
|
and do that a second time for a Debug build too:
|
|
|
|
devenv db-4.4.20\build_win32\Berkeley_DB.sln /build Debug /project db_static
|
|
|
|
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
|
|
dist\db-4.4.20\docs\index.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.
|
|
|
|
XXX The test_bsddb3 tests don't always pass, on Windows (according to
|
|
XXX me) or on Linux (according to Barry). (I had much better luck
|
|
XXX on Win2K than on Win98SE.) The common failure mode across platforms
|
|
XXX is
|
|
XXX DBAgainError: (11, 'Resource temporarily unavailable -- unable
|
|
XXX to join the environment')
|
|
XXX
|
|
XXX and it appears timing-dependent. On Win2K I also saw this once:
|
|
XXX
|
|
XXX test02_SimpleLocks (bsddb.test.test_thread.HashSimpleThreaded) ...
|
|
XXX Exception in thread reader 1:

|
|
|
|
Building for Win64:
|
|
- open a VS.NET 2003 command prompt
|
|
- run the SDK setenv.cmd script, passing /RETAIL and the target
|
|
architecture (/SRV64 for Itanium, /X64 for AMD64)
|
|
- build BerkeleyDB with the solution configuration matching the
|
|
target ("Release IA64" for Itanium, "Release AMD64" for AMD64), e.g.
|
|
devenv db-4.4.20\build_win32\Berkeley_DB.sln /build "Release AMD64" /project db_static /useenv
|
|
|
|
_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.
|
|
|
|
_ssl
|
|
Python wrapper for the secure sockets library.
|
|
|
|
Get the source code through
|
|
|
|
svn export http://svn.python.org/projects/external/openssl-0.9.8a
|
|
|
|
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 also install ActivePerl from
|
|
http://www.activestate.com/Products/ActivePerl/
|
|
as this is used by the OpenSSL build process. Complain to them <wink>.
|
|
|
|
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
|
|
--------------------
|
|
|
|
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 the ReleaseAMD64 configuration is very similar
|
|
to the Itanium configuration; make sure you use the latest version of
|
|
vsextcomp.
|
|
|
|
Building Python Using the free MS Toolkit Compiler
|
|
--------------------------------------------------
|
|
|
|
The build process for Visual C++ can be used almost unchanged with the free MS
|
|
Toolkit Compiler. This provides a way of building Python using freely
|
|
available software.
|
|
|
|
Note that Microsoft have withdrawn the free MS Toolkit Compiler, so this can
|
|
no longer be considered a supported option. The instructions are still
|
|
correct, but you need to already have a copy of the compiler in order to use
|
|
them. Microsoft now supply Visual C++ 2005 Express Edition for free, but this
|
|
is NOT compatible with Visual C++ 7.1 (it uses a different C runtime), and so
|
|
cannot be used to build a version of Python compatible with the standard
|
|
python.org build. If you are interested in using Visual C++ 2005 Express
|
|
Edition, however, you should look at the PCBuild8 directory.
|
|
|
|
Requirements
|
|
|
|
To build Python, the following tools are required:
|
|
|
|
* The Visual C++ Toolkit Compiler
|
|
no longer available for download - see above
|
|
* A recent Platform SDK
|
|
from http://www.microsoft.com/downloads/details.aspx?FamilyID=484269e2-3b89-47e3-8eb7-1f2be6d7123a
|
|
* The .NET 1.1 SDK
|
|
from http://www.microsoft.com/downloads/details.aspx?FamilyID=9b3a2ca6-3647-4070-9f41-a333c6b9181d
|
|
|
|
[Does anyone have better URLs for the last 2 of these?]
|
|
|
|
The toolkit compiler is needed as it is an optimising compiler (the
|
|
compiler supplied with the .NET SDK is a non-optimising version). The
|
|
platform SDK is needed to provide the Windows header files and libraries
|
|
(the Windows 2003 Server SP1 edition, typical install, is known to work -
|
|
other configurations or versions are probably fine as well). The .NET 1.1
|
|
SDK is needed because it contains a version of msvcrt.dll which links to
|
|
the msvcr71.dll CRT. Note that the .NET 2.0 SDK is NOT acceptable, as it
|
|
references msvcr80.dll.
|
|
|
|
All of the above items should be installed as normal.
|
|
|
|
If you intend to build the openssl (needed for the _ssl extension) you
|
|
will need the C runtime sources installed as part of the platform SDK.
|
|
|
|
In addition, you will need Nant, available from
|
|
http://nant.sourceforge.net. The 0.85 release candidate 3 version is known
|
|
to work. This is the latest released version at the time of writing. Later
|
|
"nightly build" versions are known NOT to work - it is not clear at
|
|
present whether future released versions will work.
|
|
|
|
Setting up the environment
|
|
|
|
Start a platform SDK "build environment window" from the start menu. The
|
|
"Windows XP 32-bit retail" version is known to work.
|
|
|
|
Add the following directories to your PATH:
|
|
* The toolkit compiler directory
|
|
* The SDK "Win64" binaries directory
|
|
* The Nant directory
|
|
Add to your INCLUDE environment variable:
|
|
* The toolkit compiler INCLUDE directory
|
|
Add to your LIB environment variable:
|
|
* The toolkit compiler LIB directory
|
|
* The .NET SDK Visual Studio 2003 VC7\lib directory
|
|
|
|
The following commands should set things up as you need them:
|
|
|
|
rem Set these values according to where you installed the software
|
|
set TOOLKIT=C:\Program Files\Microsoft Visual C++ Toolkit 2003
|
|
set SDK=C:\Program Files\Microsoft Platform SDK
|
|
set NET=C:\Program Files\Microsoft Visual Studio .NET 2003
|
|
set NANT=C:\Utils\Nant
|
|
|
|
set PATH=%TOOLKIT%\bin;%PATH%;%SDK%\Bin\win64;%NANT%\bin
|
|
set INCLUDE=%TOOLKIT%\include;%INCLUDE%
|
|
set LIB=%TOOLKIT%\lib;%NET%\VC7\lib;%LIB%
|
|
|
|
The "win64" directory from the SDK is added to supply executables such as
|
|
"cvtres" and "lib", which are not available elsewhere. The versions in the
|
|
"win64" directory are 32-bit programs, so they are fine to use here.
|
|
|
|
That's it. To build Python (the core only, no binary extensions which
|
|
depend on external libraries) you just need to issue the command
|
|
|
|
nant -buildfile:python.build all
|
|
|
|
from within the PCBuild directory.
|
|
|
|
Extension modules
|
|
|
|
To build those extension modules which require external libraries
|
|
(_tkinter, bz2, _bsddb, _sqlite3, _ssl) you can follow the instructions
|
|
for the Visual Studio build above, with a few minor modifications. These
|
|
instructions have only been tested using the sources in the Python
|
|
subversion repository - building from original sources should work, but
|
|
has not been tested.
|
|
|
|
For each extension module you wish to build, you should remove the
|
|
associated include line from the excludeprojects section of pc.build.
|
|
|
|
The changes required are:
|
|
|
|
_tkinter
|
|
The tix makefile (tix-8.4.0\win\makefile.vc) must be modified to
|
|
remove references to TOOLS32. The relevant lines should be changed to
|
|
read:
|
|
cc32 = cl.exe
|
|
link32 = link.exe
|
|
include32 =
|
|
The remainder of the build instructions will work as given.
|
|
|
|
bz2
|
|
No changes are needed
|
|
|
|
_bsddb
|
|
The file db.build should be copied from the Python PCBuild directory
|
|
to the directory db-4.4.20\build_win32.
|
|
|
|
The file db_static.vcproj in db-4.4.20\build_win32 should be edited to
|
|
remove the string "$(SolutionDir)" - this occurs in 2 places, only
|
|
relevant for 64-bit builds. (The edit is required as otherwise, nant
|
|
wants to read the solution file, which is not in a suitable form).
|
|
|
|
The bsddb library can then be build with the command
|
|
nant -buildfile:db.build all
|
|
run from the db-4.4.20\build_win32 directory.
|
|
|
|
_sqlite3
|
|
No changes are needed. However, in order for the tests to succeed, a
|
|
copy of sqlite3.dll must be downloaded, and placed alongside
|
|
python.exe.
|
|
|
|
_ssl
|
|
The documented build process works as written. However, it needs a
|
|
copy of the file setargv.obj, which is not supplied in the platform
|
|
SDK. However, the sources are available (in the crt source code). To
|
|
build setargv.obj, proceed as follows:
|
|
|
|
Copy setargv.c, cruntime.h and internal.h from %SDK%\src\crt to a
|
|
temporary directory.
|
|
Compile using "cl /c /I. /MD /D_CRTBLD setargv.c"
|
|
Copy the resulting setargv.obj to somewhere on your LIB environment
|
|
(%SDK%\lib is a reasonable place).
|
|
|
|
With setargv.obj in place, the standard build process should work
|
|
fine.
|
|
|
|
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.
|
