'''take the win32 bit versions.'''

= Install python and necessary packages =

I recommend to install a python distribution which is packed with several packages already.

== Winpython ==
You could consider winpython, which includes Ipython, numpy, scipy. matplotlib etc.:<br>
[https://code.google.com/p/winpython Homepage]

Make a folder: '''C:\WinPython27'''.<br>
Run the downloaded winpython exe file, and extract to: '''C:\WinPython27'''.<br>
Open '''WinPython Control Panel''' in ex. '''C:\WinPython27\WinPython-32bit-2.7.x'''<br>
Drag the 4 above mentioned packakes, into the window, and install the packages.<br>
For a command window, use the '''WinPython Command Prompt''' found in '''C:\WinPython27\WinPython-32bit-2.7.x''', which fixes path issues for finding python.

=== Trick to set variables in cmd ===
Make a folder '''own''' in '''C:\WinPython27\WinPython-32bit-2.7.x\scripts''' and <br>
copy '''C:\WinPython27\WinPython-32bit-2.7.x\scripts\env.bat''' to '''C:\WinPython27\WinPython-32bit-2.7.x\scripts\own\pytming.bat'''<br>
and copy '''C:\WinPython27\WinPython-32bit-2.7.x\scripts\cmd.bat''' to '''C:\WinPython27\WinPython-32bit-2.7.x\scripts\own\cmdpytming.bat'''<br>

Modify '''pytming.bat''' from
<source lang="python">
set WINPYDIR=%~dp0..\python-2.7.5
</source>
to include '''..\'''
<source lang="python">
set WINPYDIR=%~dp0..\..\python-2.7.5
</source>

Modify '''cmdpytming.bat''' from
<source lang="python">
call %~dp0env.bat
</source>
to
<source lang="python">
call %~dp0pytming.bat
</source>

=== Trick to add .bat files to PATH ===
If you have permission to change the Environment Variables in windows, you can add the '''pytming.bat''' and '''cmdpytming.bat''' to your path.<br>
Right click Computer -> properties -> Advanced system settings -> Environment Variables -> User variables ->  Edit: PATH <br>
Add to end of the Variable value:
 ;C:\WinPython27\WinPython-32bit-2.7.x\scripts\own
In any folder, hold "Shift" and right click, "Open command window here". Write:
<source lang="powershell">
pytming
python
</source>

= Install minGW =
Download [http://sourceforge.net/projects/mingw/files/Installer/mingw-get-inst/ mingw-get-inst], and run it. [http://www.mingw.org/wiki/Getting_Started If you need more help, read this], but you should just do this.
# Install to: C:\MinGW
# Take all options when installing (about 450 MB)
# Take the "pre" package option

After install, edit '''C:\MinGW\msys\1.0\msys.bat'''. <br>
Insert at second line a call to our variables:
<source lang="powershell">
@echo off
call C:\WinPython27\WinPython-32bit-2.7.5.1\scripts\env.bat

= Install Subversion checkout of relax =
{{historical svn}}
Install a subversion client. For example: http://tortoisesvn.net/

Right click in winpython folder: '''C:\WinPython27''', and select '''SVN Checkout'''. Write the path:
 svn://svn.gna.org/svn/relax/branches/relax_disp relax_disp_32_ming

= Build relax = 
Open the '''MinGW Shell''' from the start menu. <br>
Write here: NOTE, you can paste into the terminal, using the little icon in top left corner, Edit, Paste
<source lang="bash">
cd /c/WinPython27/relax_disp_32_ming
python /c/WinPython27/WinPython-32bit-2.7.5.1/python-2.7.5/Scripts/scons.py install
</source>
