The standalone Windows installer for Mercurial is built in a somewhat

jury-rigged fashion.

It has the following prerequisites, at least as I build it:

  Python for Windows

      http://www.python.org/ftp/python/2.4.3/python-2.4.3.msi

  MinGW

      http://www.mingw.org/

  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)

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

  The py2exe distutils extension

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

  GnuWin32 gettext utility

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

  Inno Setup

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

      Get and install ispack-5.3.4.exe which 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/

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:

  python setup.py build -c mingw32

  python setup.py py2exe -b 1

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

mingw32 py2exe -b 1" 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.

Copy add_path.exe into the dist directory that just got created.

If you are using Python up to version 2.5.4, copy mfc71.dll into the dist

directory that just got created.

If you are using Python 2.6 or later, after installing the Visual C++ 2008

redistributable package copy into the dist directory that just got created the

following files:

  - from the directory starting with

    Windows/WinSxS/x86_Microsoft.VC90.CRT_1fc8b3b9a1e18e3b_9.0.21022.8

    the files named: msvcm90.dll, msvcp90.dll and msvcr90.dll

  - from the directory starting with

    Windows/WinSxS/x86_Microsoft.VC90.MFC_1fc8b3b9a1e18e3b_9.0.21022.8

    the files named: mfc90.dll, mfc90u.dll, mfcm90.dll and mfcm90u.dll

  - from the directory named Windows/WinSxS/Manifests, the manifest file

    starting with x86_Microsoft.VC90.CRT_1fc8b3b9a1e18e3b_9.0.21022.8

    (rename it to Microsoft.VC90.CRT.manifest) and the manifest file starting

    with x86_Microsoft.VC90.MFC_1fc8b3b9a1e18e3b_9.0.21022.8 (rename it to

    Microsoft.VC90.MFC.manifest)

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

  cd doc

  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.

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

following:

  echo [build] > setup.cfg

  echo compiler=mingw32 >> setup.cfg

  python setup.py py2exe -b 1

  cd doc

  cd ..

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

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