The standalone Windows installer for Mercurial is built in a somewhat

jury-rigged fashion.

It has the following prerequisites. Ensure to take the packages

matching the mercurial version you want to build (32-bit or 64-bit).

  Python 2.6 for Windows

      http://www.python.org/download/releases/

  A compiler:

    either MinGW

      http://www.mingw.org/

    or Microsoft Visual C++ 2008 SP1 Express Edition

      http://www.microsoft.com/express/Downloads/Download-2008.aspx

  Python for Windows Extensions

      http://sourceforge.net/projects/pywin32/

  mfc71.dll (just download, don't install; not needed for Python 2.6)

      http://starship.python.net/crew/mhammond/win32/

  Visual C++ 2008 redistributable package (needed for >= Python 2.6 or if you compile with MSVC)

    for 32-bit:

      http://www.microsoft.com/downloads/details.aspx?FamilyID=9b2da534-3e03-4391-8a4d-074b9f2bc1bf

    for 64-bit:

      http://www.microsoft.com/downloads/details.aspx?familyid=bd2a6171-e2d6-4230-b809-9a8d7548c1b6

  The py2exe distutils extension

      http://sourceforge.net/projects/py2exe/

  GnuWin32 gettext utility (if you want to build translations)

      http://gnuwin32.sourceforge.net/packages/gettext.htm

  Inno Setup

      http://www.jrsoftware.org/isdl.php#qsp

      Get and install ispack-5.3.10.exe or later (includes Inno Setup Processor),

      which is necessary to package Mercurial.

  ISTool - optional

      http://www.istool.org/default.aspx/

  add_path (you need only add_path.exe in the zip file)

      http://www.barisione.org/apps.html#add_path

  Docutils

      http://docutils.sourceforge.net/

  CA Certs file

      http://curl.haxx.se/ca/cacert.pem

And, of course, Mercurial itself.

Once you have all this installed and built, clone a copy of the

Mercurial repository you want to package, and name the repo

C:\hg\hg-release.

In a shell, build a standalone copy of the hg.exe program.

Building instructions for MinGW:

  python setup.py build -c mingw32

  python setup.py py2exe -b 2

Note: the previously suggested combined command of "python setup.py build -c

mingw32 py2exe -b 2" doesn't work correctly anymore as it doesn't include the

extensions in the mercurial subdirectory.

If you want to create a file named setup.cfg with the contents:

[build]

compiler=mingw32

you can skip the first build step.

Building instructions with MSVC 2008 Express Edition:

  for 32-bit:

    "C:\Program Files\Microsoft Visual Studio 9.0\VC\vcvarsall.bat" x86

    python setup.py py2exe -b 2

  for 64-bit:

    "C:\Program Files\Microsoft Visual Studio 9.0\VC\vcvarsall.bat" x86_amd64

    python setup.py py2exe -b 3

Copy add_path.exe and cacert.pem files into the dist directory that just got created.

If you are using Python 2.6 or later, or if you are using MSVC 2008 to compile

mercurial, you must include the C runtime libraries in the installer. To do so,

install the Visual C++ 2008 redistributable package. Then in your windows\winsxs

folder, locate the folder containing the dlls version 9.0.21022.8.

For x86, it should be named like x86_Microsoft.VC90.CRT_(...)_9.0.21022.8(...).

For x64, it should be named like amd64_Microsoft.VC90.CRT_(...)_9.0.21022.8(...).

Copy the files named msvcm90.dll, msvcp90.dll and msvcr90.dll into the dist

directory.

Then in the windows\winsxs\manifests folder, locate the corresponding manifest

file (x86_Microsoft.VC90.CRT_(...)_9.0.21022.8(...).manifest for x86,

amd64_Microsoft.VC90.CRT_(...)_9.0.21022.8(...).manifest for x64), copy it in the

dist directory and rename it to Microsoft.VC90.CRT.manifest.

Before building the installer, you have to build Mercurial HTML documentation

(or fix mercurial.iss to not reference the doc directory):

  cd doc

  mingw32-make html

  cd ..

If you use ISTool, you open the C:\hg\hg-release\contrib\win32\mercurial.iss

file and type Ctrl-F9 to compile the installer file.

Otherwise you run the Inno Setup compiler.  Assuming it's in the path

you should execute:

  iscc contrib\win32\mercurial.iss /dVERSION=foo

Where 'foo' is the version number you would like to see in the

'Add/Remove Applications' tool.  The installer will be placed into

a directory named Output/ at the root of your repository.

If the /dVERSION=foo parameter is not given in the command line, the

installer will retrieve the version information from the __version__.py file.

If you want to build an installer for a 64-bit mercurial, add /dARCH=x64 to

your command line:

  iscc contrib\win32\mercurial.iss /dARCH=x64

To automate the steps above you may want to create a batchfile based on the

following (MinGW build chain):

  echo [build] > setup.cfg

  echo compiler=mingw32 >> setup.cfg

  python setup.py py2exe -b 2

  cd doc

  mingw32-make html

  cd ..

  iscc contrib\win32\mercurial.iss /dVERSION=snapshot

and run it from the root of the hg repository (c:\hg\hg-release).
