Yaybu on Windows

This process has been observed to work on 32-bit Windows XP and Windows 7.

Let's set up a nice PATH:

set PATH=C:\Git\bin;C:\Python27;C:\MinGW\bin;%PATH%

Install msysgit (the official windows port of Git):

• URL is https://msysgit.googlecode.com/files/Git-1.8.3-preview20130601.exe
• Install to C:Git
• Default line ending mode (converts to windows on checkout / to unix on commit)
• Don't bother with any shell integration, but the font is nice.

Install python2.7, py2exe, pycrypto from installers:

• http://www.python.org/ftp/python/2.7.5/python-2.7.5.msi
• http://downloads.sourceforge.net/project/py2exe/py2exe/0.6.9/py2exe-0.6.9.win32-py2.7.exe
• http://www.voidspace.org.uk/downloads/pycrypto26/pycrypto-2.6.win32-py2.7.exe

Install MinGW Installation Manager Setup Tool:

• http://sourceforge.net/projects/mingw/files/Installer/mingw-get-setup.exe/download

There is no need to let it do GUI stuff. You can then install gcc and tools:

mingw-get install gcc mingw-utils

At the time of writing this seems to yield a broken environment - so copy some DDL's around. To fix cc1plus:

cd C:\MinGW
copy bin\libgmp-10.dll libexec\gcc\mingw32\4.7.2\
copy bin\libmpc-2.dll libexec\gcc\mingw32\4.7.2\
copy bin\libmpfr-1.dll libexec\gcc\mingw32\4.7.2\

It might be that libgcc_s_dw2-1.dll, libiconv-2.dll or libintl-8.dll need similar.

We need to generate a def file and then a a file before we'll be able to build against our Python install:

cd c:\Python27\libs
pexports c:\windows\system32\python27.dll > python26.def
dlltool -C -d python27.def -l libpython27.a

You can check the exported symbols with nm (look for I for import symbol):

nm libpython27.a

Out of the box python2.7 will not be able to use this version of mingw32. Edit C:\Python27\Lib\distutils\cygwinccompiler.py and remove all mentions of -mno-cygwin.

Python needs to be told to use mingw32. You can do this with a C:\Python27\Lib\distutils\distutils.cfg:

[build]
compiler=mingw32

The default site.py has an abs_file that seems to break when using py2exe. Patch abs_file to catch ImportErrors:

 def abs__file__():
     """Set all module' __file__ attribute to an absolute path"""
     for m in sys.modules.values():
         if hasattr(m, '__loader__'):
             continue   # don't mess with a PEP 302-supplied __file__
         try:
             m.__file__ = os.path.abspath(m.__file__)
-        except (AttributeError, OSError):
+        except (AttributeError, OSError, ImportError):
             pass

You are now ready to get the code:

git clone https://github.com/yaybu/Yaybu.exe C:\Yaybu.exe
cd C:\Yaybu.exe

Install setuptools using the ez_setup.py script provided:

python ez_setup.py

py2exe will break with setuptools because it is compressed. A better way to deal with it is needed, but for now:

python -m easy_install --always-unzip --upgrade "setuptools<1.0"

(You can upgrade to the active version because it detects it is already the latest version).

Then install pip and get the requirements:

python -m easy_install pip
python -m pip install -r requirements.txt

This doesn't actually install any yay/yaybu code (for which you have a few choices):

python -m pip install git+git://github.com/yaybu/yay.git#egg=yay
python -m pip install git+git://github.com/yaybu/yaybu.git#egg=yaybu

or (if you check out the code by hand or with buildbot):

python -m pip install -e src/yay
python -m pip install -e src/yaybu

Running tests

There are extra deps for the tests:

python -m pip install nose2 unittest2 mock fakechroot
python -m nose2 yay yaybu

Building an exe

Run py2exe:

python setup.py py2exe

This will create a directory with python extensions, a library.zip and a YaybuShell.exe. This binary is equivalent to the yaybu command on a unix system.
