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 PCbuild9 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 F6 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. The 32bit builds end up in the solution folder PCbuild9 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. 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 PCbuild9 is ..\dist\py3k\PCbuild9\, 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 PCbuild9 directory contains a Python script which automates all steps. Run the script in a Visual Studio 2009 command prompt with python build_tkinter.py Win32 Use x64 instead of Win32 for the x64 platform. Build Tcl first --------------- Use "Start -> All Programs -> Microsoft Visual Studio 2008 -> Visual Studio Tools -> Visual Studio 2008 Command Prompt" to get a shell window with the correct environment settings cd dist\tcl8.4.16\win nmake -f makefile.vc nmake -f makefile.vc INSTALLDIR=..\..\tcltk install XXX Should we compile with OPTS=threads?

Files with failing tests: canvImg.test scrollbar.test textWind.test winWm.test Built Tix --------- cd dist\tix-8.4.0\win nmake -f python9.mak nmake -f python9.mak install 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 PCbuild9\. 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. The standard and professional version of VS 2008 builds the necessary libraries in a pre-link step of _bsddb. However the express edition is missing some pieces and you have to build the libs yourself. 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 as 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. 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 --------------------------- 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 PCbuild9 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 macros) * 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) * release (release macros) * 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. 
Tip: Filter by directory path e.g. /media app.js to search for public/media/app.js.
Tip: Use camelCasing e.g. ProjME to search for ProjectModifiedEvent.java.
Tip: Filter by extension type e.g. /repo .js to search for all .js files in the /repo directory.
Tip: Separate your search with spaces e.g. /ssh pom.xml to search for src/ssh/pom.xml.
Tip: Use ↑ and ↓ arrow keys to navigate and return to view the file.
Tip: You can also navigate files with Ctrl+j (next) and Ctrl+k (previous) and view the file with Ctrl+o.
Tip: You can also navigate files with Alt+j (next) and Alt+k (previous) and view the file with Alt+o.
