How to build Python 2.7.5 using Visual Studio 2012 Express on Windows 8 64-bit

My goal with these instructions is to produce a DEBUG build on x86_64 (AMD64 or x64). I'm working on a Python extension that is currently crashing on Windows, but work fine in Linux. I will be building debug version of Numpy and Matplotlib after the DEBUG version of Python is created with these instructions.

References:

VS2010

Prepare Environment

1. Create a directory to store the Python source tree and dependencies, I called mine python_build.

2. Download Python 2.7.5 source from python.org and unzip it to python_build

3. Download and install an SVN command-line client (Try SlickSVN)

4. Download and install Perl64

5. Download and install Visual Studio Express 2012

Test Environment

1. Open a shell

2. Bring in the msvc compiler environment for x64 by doing:

  • call "C:\Program Files (x86)\Microsoft Visual Studio 11.0\VC\vcvarsall.bat" x86_amd64
    Verify by typing 'cl.exe':
    Microsoft (R) C/C++ Optimizing Compiler Version 17.00.60610.1 for x64

3. Try running the svn client: 'svn --version':

  • svn, version 1.8.3-SlikSvn-1.8.3-X64 (SlikSvn/1.8.3) X64
       compiled Sep  4 2013, 16:04:02 on x86_64/x86-microsoft-windows6.1.7601
    
    Copyright (C) 2013 The Apache Software Foundation.

4. Try running perl: 'perl --version'

  • This is perl 5, version 16, subversion 3 (v5.16.3) built for MSWin32-x64-multi-thread

Download dependencies

Use the buildbot tools to grab the external dependencies:

  • cd Python2.7.5
    Tools\buildbot\external-common.bat

Compile External Dependencies

  • cd Python2.7.5

Manually Build Openssl 1.0.1e

1. Download and unzip openssl-1.0.1e.tar.gz

2. Configure openssl:

  • cd openssl-1.0.1e
    perl Configure --openssldir=%CD%\ enable-camellia disable-idea VC-WIN64A

3. IMPORTANT, I guess perl creates "symobolic" links inside the include directory which the openssl build environment understands. However Visual Studio doesn't understand them:

  • Example Visual Studio Error message:
  • C:\Users\Nick\Downloads\python_build\openssl-1.0.1e\include\openssl/evp.h(1): error C2059: syntax error : '!'
    To correct the problem, copy the headers over their symbolic links. I used a BASH shell in Cygwin to do this:
  • cd openssl-1.0.1e/include/openssl
    for f in *.h; do cp $f $f.nick; mv $f.nick $f; done

4. Build with these commands:

  • ms\do_win64a.bat
    nmake -f ms\ntdll.mak

Convert Visual Studio 2008 Solution

1. Open Python-2.7.5\PCbuild\pcbuild.sln with Visual Studio 2012 Express

2. Click OK to perform the "One-Way" upgrade on all the project files.

3. Immediately close Visual Studio 2012 Express

Patch Project Files

See this diff file: PCbuild_patches.txt

I've also just zipped up the project files so you can just unzip them into PCbuild: python-2.7.5-amd64-pcbuild.zip

Build Python

1. Open Python-2.7.5\PCbuild\pcbuild.sln

2. Select 'DEBUG' and 'x64' For the configuration.

3. Click 'Build' -> 'Build Solution' (F7)
