-Building Python using VC++ 8.0
--------------------------------------
-This directory is used to build Python for Win32 platforms, e.g. Windows
-95, 98 and NT. It requires Microsoft Visual C++ 8.0
-(a.k.a. Visual Studio 2005).
-(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,
- python25.{dll, lib} in Release mode)
- NOTE: in previous releases, this subproject was
- named after the release number, e.g. python20.
-
-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: python25_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
-pythoncore_pgo
- .dll and .lib, a variant of pythoncore that is optimized through a
- Profile Guided Optimization (PGO), employing pybench as the profile
- case to optimize for. The results are produced as a python25.{dll,lib}
- in the subfolder 'pythoncore_pgo'. To use this instead of the
- standard Python dll place this dll with the python.exe.
-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
- cd dist\tcl8.4.12\win

-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')

-
- 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 0.8.
-
-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.
-
-Requirements
-
- To build Python, the following tools are required:
-
- * The Visual C++ Toolkit Compiler
- from http://msdn.microsoft.com/visualc/vctoolkit2003/
- * 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.

+ 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 0.8.
+
+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.
+
+Requirements
+
+ To build Python, the following tools are required:
+
+ * The Visual C++ Toolkit Compiler
+ from http://msdn.microsoft.com/visualc/vctoolkit2003/
+ * 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.
