===============================
Setting Up A Windows Build Host
===============================
This document describes the steps taken to set up a Windows build host. It is
intended to be step-by-step instructions of what packages need to be installed,
where they can be gotten from, and how they are configured.
Baseline
========
This was written as a step-by-step as I set up the Amazon EC2 'desolation'
instance. This was based on an Amazon Windows 2003 instance. Also note that for
Amazon EC2, all programs were installed into the "C:" drive, as the "D:" drive
is essentially ``/tmp`` and is not preserved between launched instances.
Install Packages
================
1) Download cygwin's setup.exe from http://www.cygwin.com
At present the current version is 1.5.25-15. This is used primarily to
install the build scripts and gcc-mingw. Note that we explicitly *don't*
install cygwin's python or bzr package. As we are only interested in
running the native version of bzr. For information on running the cygwin
port of bzr, look elsewhere.
Probably not all of these packages are necessary, but they make life easier.
a) gcc-mingw32
b) make
c) openssh
d) rsync
e) vim
f) wget
g) zip
h) unzip
i) patch
j) gettext-devel # brings 'msgfmt'
2) Download the supported versions of python from http://www.python.org
a) python 2.6.4
b) python 2.5.4 http://www.python.org/ftp/python/2.5.4/python-2.5.4.msi
c) python 2.4.4 (there is no Windows installer for 2.4.5 or 2.4.6)
http://www.python.org/ftp/python/2.4.4/python-2.4.4.msi
Note that for Amazon EC2, all of these were installed int
3) Configure 'distutils' for the compiler that you will be using. For python
2.4 and 2.5 we use gcc-mingw32, for 2.6 we use Visual Studio 2008.
Edit ``D:\Python25\Lib\disutils\distutils.cfg`` (you have to create the
file). You want to add a section like::
[build]
compiler = mingw32
This also requires 'fixing' the cygwin gcc installation so that distutils
can find it. Specifically, it knows to look for ``gcc.exe`` however, the
latest versions of cygwin start using "alternatives" and making ``gcc`` just
a symlink.
You also need to add ``C:\cygwin\bin`` and ``C:\cygwin\lib`` into your
environment path. This is generally done with::
Right Click My Computer / Properties / Advanced / Environment Variables
System Variables / Select 'PATH' / Edit
4) Download important python libraries. At the moment, the official Windows
all-in-one installer is built using python 2.5. We will likely soon switch
to python 2.6.
a) http://pypi.python.org/pypi/setuptools
Installing this first should make it easier to install some of the other
tools. To install something using easy install, it is generally best to
open up a ``cmd.exe`` shell (*not* a cygwin shell) and do::
cd C:\Python25
python.exe Scripts\easy_install-script.py -Z -O1 PACKAGE
The '-Z' tells it to install as a regular directory. This generally works
better with py2exe.
b) pywin32 http://sourceforge.net/projects/pywin32/files/
c) easy_install paramiko
This will also bring in PyCrypto and compile it, so it is important to
have configured step (3) correctly.
d) easy_install Pyrex (or Cython)
Note, you should probably install pyrex for all versions of python. All
of them need to run 'setup.py bdist_wininst' and so it is good to have it
build automatically, rather than setting up an explicit build order based
on which one has pyrex.
e) easy_install cogapp
f) install py2exe (easy_install failed)
http://sourceforge.net/projects/py2exe/files/
g) easy_install docutils
h) Install PyQt
http://www.riverbankcomputing.co.uk/software/pyqt/download
Currently they only seem to offer PyQt 4.4.3 for python 2.5 and PyQt
4.6.1 for python 2.6. They generally don't make it easy to install old
versions of PyQt.
i) Install pyreadline
https://launchpad.net/pyreadline/+download
j) easy_install pygments
k) Patch pycrypto, so that it supports older Windows installs. (see bugs
#248522, #272791, #497733). The direct link to the patch is:
http://launchpadlibrarian.net/16133025/win32_clock.patch
This may not end up necessary w/ pycrypto 2.1, especially if paramiko can
be taught to use the new functionality (avoiding the warning).
l) easy_install testtools
5) Get Pageant, not strictly necessary, but it is a pretty good ssh-agent for
Windows, and paramiko knows how to use keys from Pageant.
http://www.chiark.greenend.org.uk/~sgtatham/putty/download.html
Note that you probably want to set the environment variable
``BZR_SSH=paramiko`` at this time. Otherwise it will try to use the
``ssh.exe`` that it finds on your PATH (as configured in step 3), and
cygwin's openssh does *not* know how to access Pageant.
I usually get the 'all-in-one' installer, but only because it is easier. You
only really need ``pageant.exe`` and possibly ``puttygen.exe``.
If you do this, you'll probably also want to install a shortcut to
``pageant.exe`` in Start / Programs / Startup so that it always starts when
you log in (though you still have to manually add your SSH keys.)
Note that on the Amazon EC2 machine, I'm having problems with temp files
being created without the permission for the current user to actually read
them. They seem to be owned by ``Administrator`` rather than by
``Administrators``.
6) Install bzr. Usually it is easiest to just get the latest all-in-one
installer from https://launchpad.net/bzr/+download
7) Install INNOSetup from:
http://www.jrsoftware.org/isdl.php
After installing, you'll want to add ``C:\Program Files\Inno Setup 5`` to
your PATH.
8) Fix distutils for the specific version of gcc. Distutils in python2.4.4 has
a bug where it assumes version strings have only 3 digits. The fix is to
just change one '?' in the regex into a '*'::
--- version.py 2009-11-05 14:41:47.497212900 -0800
+++ version.py 2009-11-05 14:39:57.684712900 -0800
@@ -97,7 +97,7 @@
in the distutils documentation.
"""
- version_re = re.compile(r'^(\d+) \. (\d+) (\. (\d+))? ([ab](\d+))?$',
+ version_re = re.compile(r'^(\d+) \. (\d+) (\. (\d+))* ([ab](\d+))?$',
re.VERBOSE)
9) If you want to build in the source tree, you need the zlib dll and
associated libraries, put somewhere on your path. The buildout routines grab
this directly and add it to the build path, but that doesn't work for
``setup.py``.
http://www.zlib.net/zlib123-dll.zip
I usually download and extract this to something like ``C:\local\`` so that
I end up with a ``C:\local\lib`` and ``C:\local\include`` directory. I then
modify the ``distutils.cfg`` file to tell the compiler where to find these
headers and libraries::
[build_ext]
include-dirs = C:/local/include
library-dirs = C:/local/lib
Note that you'll probably want to put the ``zlib1.dll`` into your path. You
can:
1) Add ``C:\local`` to your PATH variable in
"My Computer/Properties/Advanced/Environment Variables"
2) More logically, move ``zlib1.dll`` to either 'lib' or 'bin'
subdirectories and add that.
3) Copy it to ``C:\Windows\``.
I recommend 3, mostly because lots of apps will want to use zlib1.dll in the
long run. (You may already have it.)
10) Install Visual Studio 2008 Professional
http://www.microsoft.com/downloads/details.aspx?FamilyId=83C3A1EC-ED72-4A79-8961-25635DB0192B&displaylang=en
This is a 3GB DVD iso image. You can mount it directly with Microsofts
iso mounting utility:
http://download.microsoft.com/download/7/b/6/7b6abd84-7841-4978-96f5-bd58df02efa2/winxpvirtualcdcontrolpanel_21.exe
You need at least Windows XP (which introduced direct iso support, I
believe.)
Note that there is a Service Pack 1 for Visual Studio. The ISO can be
downloaded here:
http://www.microsoft.com/downloads/thankyou.aspx?familyId=27673c47-b3b5-4c67-bd99-84e525b5ce61&displayLang=en
However, on EC2, there isn't enough room on C: to actually run the
installer. You need approx 6GB of free disk space. And EC2 only gives your
10GB and Windows itself takes up about 5GB. So we are currently running
stock VS 2008 with no service packs. (Even installing VS 2008 to a
different drive doesn't leave enough room on C: to run the upgrader.)
When installing on EC2, it seems their 2003 Server comes with a Visual
Studio key already supplied. There is also the possibility of using Visual
Studio Express Edition, but it is currently unable to compile TortoiseBzr.
