-Building Python using VC++ 9.0
-------------------------------
-
-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.
-
-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 not 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: python27_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)
-PC/VS8.0/
- 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 available 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 msvcrt90.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
-
-Python-controlled subprojects that wrap external projects:
-_bsddb
- Wraps Berkeley DB 4.7.25, which is currently built by _bsddb.vcproj.
- project.
-_sqlite3
- Wraps SQLite 3.6.21, which is currently built by sqlite3.vcproj.
-_tkinter
- 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 ..\externals\tcltk for 32-bit or
- ..\externals\tcltk64 for 64-bit (relative to this directory). See below
- for instructions to build Tcl/Tk.
-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/bzip2-1.0.6
-
- ** NOTE: if you use the Tools\buildbot\external(-amd64).bat approach for
- obtaining external sources then you don't need to manually get the source
- above via subversion. **
-
-_ssl
- Python wrapper for the secure sockets library.
-
- Get the source code through
-
- svn export http://svn.python.org/projects/external/openssl-1.0.2a
-
- ** NOTE: if you use the Tools\buildbot\external(-amd64).bat approach for
- obtaining external sources then you don't need to manually get the source
- above via subversion. **
-
- The NASM assembler is required to build OpenSSL. If you use the
- Tools\buildbot\external(-amd64).bat method for getting sources, it also
- downloads a version of NASM, which the ssl build script will add to PATH.
- Otherwise, you can download the NASM installer from
- http://www.nasm.us/
- and add NASM to your PATH.
-
- You can also install ActivePerl from
- http://www.activestate.com/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.
-
-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
-..\externals (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
-_bsddb.vcproj and sqlite3.vcproj files, which will remove the need for
-Tcl/Tk to be built separately via a batch file.
-
-Building for Itanium
---------------------
-
-Official support for Itanium builds have been dropped from the build. Please
-contact us and provide patches if you are interested in Itanium builds.
-
-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
-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.
-
-http://msdn.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.
