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.



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 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:

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

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

Download dependencies

Use the buildbot tools to grab the external dependencies:

Compile External Dependencies

Manually Build Openssl 1.0.1e

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

2. Configure openssl:

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.

4. Build with these commands:

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:

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)
