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.

Many thanks to sebastien.sable for their page VS2010, which I followed to create 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 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

Compile External Dependencies
cd Python2.7.5 Tools\buildbot\external-amd64.bat
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):
- You should now see a successful DEBUG build:
========== Build: 25 succeeded, 0 failed, 0 up-to-date, 1 skipped ==========
Install Python
Now that Python has been built, I will used the script below to install executables and libraries under one directory. Building the selfinstaller won't work in Visual Studio Express, also, the MSI tool won't package up any of the debug libraries, since these don't get updated by Windows Update, doing so would be a security risk.
So, I used this FIXME script to install do a target directory:
