TortoiseHg and Mercurial installer builder for Windows


contrib/ - Bundled libraries and utilities external to (T)HG misc/ - Miscellaneous files used to build packages

=== Mercurial Prerequisites ===

  • Python 2.6.6 C:Python26 must be in your PATH

    You will need the x86 Python interpreter to generate x86 MSI packages and the x64 Python interpreter to generate x64 MSI packages. You'll need to install the Python package pre-reqs for each interpreter.

  • C++ Compiler

    Get the gratis "Microsoft Windows SDK for Windows 7 and .NET Framework 3.5 SP1" from

    See the win32/shellext/README.txt file in the TortoiseHg source for details on installing this package.

    If you already have Visual Studio 2008, installing the SDK will confuse DISTUTILS when it tries to build Mercurial's C extensions. Simply comment out the line in that sets the DISTUTILS_USE_SDK environment variable, and distutils will use VC2008 to build Mercurial and our build scripts will use SDK's compiler to build the THG shell extension. These are supposedly the same compiler, so it should be ok.

    Following the advice in might be needed for x64 builds ("copy VCbinvcvars64.bat into VCbinamd64vcvarsamd64.bat")

  • gettext

    We recommend the 'Setup program' from

  • py2exe

    Get the latest version for your Python release

  • Windows Installer XML

    Get the latest stable 3.0 package from

  • Docutils

    Building HTML man pages for Mercurial requires the script from docutils. The easiest way to get docutils is to install setuptools (below), then: C:Python26Scriptseasy_install.exe docutils

=== Building TortoiseHg documentation ===

To build just the TortoiseHg docs, install the packages below then:

python --thg-doc

  • setuptools (provides easy_install.exe)

    Get the latest version for your Python release We're using:


  • sphinx, docutils, jinja2, pygments, etc

    (requires easy_install from setuptools) The sphinx package has dependencies for docutils, jinja, etc, so installing sphinx pulls in all the other prerequisites.

    easy_install sphinx

  • MiKTeX (to build PDF docs) You can chose for it to automatically download packages when it needs them, else the first time it builds PDF docs it will require much user interaction. We're using:


  • HTML Help Workshop (to build CHM docs)

    This should come with the Windows SDK, but also available here:

=== Building TortoiseHg Installer Packages ===

To build TortoiseHg MSI packages, you need the Mercurial prerequisites, TortoiseHg documentation prerequisites, and these packages:

== Build Steps ==

It's entirely automated. Ensure C:Python26 is in your path, then run:

python --help

To build x64 packages, you use:

C:python26x64python.exe --help

== Example for preparing a working build machine from scratch ==

Below is a detailed journal of steps that worked for setting up a TortoiseHg build machine from scratch.

1) Windows 7 x64 SP1 installed, logged in as <user> 2a) Installed python-2.6.6.amd64.msi in C:Python26-x64, added this dir to PATH 2b) Installed python-2.6.6.msi in C:Python26, deselected "Register Extensions"

on feature selection during install to not have this Python as default
  1. Installed "Microsoft Windows SDK for Windows 7 and .NET Framework 3.5 SP1"

4) Installed gettext-0.14.4 5a) Installed py2exe-0.6.9.win64-py2.6.amd64.exe in C:Python26-x64 5b) Installed py2exe-0.6.9.win32-py2.6.exe in C:Python26 6a) Installed setuptools-0.6c11.win32-py2.6.exe in C:Python26 6b) Downloaded as explained on

and ran "C:Python26-x64python.exe"

7a) Ran "C:Python26Scriptseasy_install.exe docutils" 7b) Ran "C:Python26-x64Scriptseasy_install.exe docutils" 8a) Ran "C:Python26Scriptseasy_install.exe sphinx" 8b) Ran "C:Python26-x64Scriptseasy_install.exe sphinx" 9) Installed "Basic MiKTeX 2.9" Installer, setting "Install missing packages

on the fly" to "Yes"

10a) Installed PyQt-Py2.6-x64-gpl-4.8.5-1.exe in C:Python26-x64 10b) Installed PyQt-Py2.6-x86-gpl-4.8.5-1 in C:Python26 11a) Installed in C:Python26-x64 11b) Installed pywin32-216.win32-py2.6.exe in C:Python26 12) Installed Wix3.msi from 13) Installed htmlhelp.exe from

14a) Installed comtypes-0.6.2.win32.exe 14b) Ran "C:Python26-x64Scriptseasy_install.exe comtypes" 15) Donloaded and from and extracted the svn and libsvn folders under C:Python*libsite-packages
  1. Installed tortoisehg-2.1.2-hg-1.9.1-x64.msi, then logoff/logon
  2. Created empty folder C:Users<user>hgrepos, opened cmd.exe in that folder
  3. Ran "hg clone"
  4. cd thg-build/winbuild
  5. Ran "C:Python26python.exe --thg-dev" -> built a x86 msi
  6. Ran "C:Python26-x64python.exe --thg-dev" -> built a x64 msi
