= STOP Download preparation =This guide should follow [http://www.nmr-relax.com/windows_devel.html Homepage for MS Windows development platform]
'''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\pyt32.bat'''<br>
and copy '''C:\WinPython27\WinPython-32bit-2.7.x\scripts\cmd.bat''' to '''C:\WinPython27\WinPython-32bit-2.7.x\scripts\own\cmdpyt32.bat'''<br>
Modify '''pyt32.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 '''cmdpyt32.bat''' from
<source lang="python">
call %~dp0env.bat
</source>
to
<source lang="python">
call %~dp0pyt32.bat
</source>
=== Trick to add .bat files to PATH ===
If you have permission to change the Environment Variables in windows, you can add the '''pyt32.bat''' and '''cmdpyt32.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">
pyt32
python
</source>
= Install Visual Studio Express 2012 for Windows Desktop =
[http://msdn.microsoft.com/en-us/library/vstudio/hs24szh9.aspx See versions of VS 2012 here].<br>
For 32 bit compiling, you will only need, '''Visual Studio Express for Windows Desktop'''.<br>
From http://www.microsoft.com/visualstudio/eng/downloads, download and install: [http://go.microsoft.com/?linkid=9816758 Visual Studio 2012 Express for Windows Desktop].<br>
Skip all extra packages install. After install, just exit any program, which opened after install.
= Install Subversion checkout of relax =
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/trunk
svn://svn.gna.org/svn/relax/branches/relax_disp relax_disp_32
== Bugfix scons for 32bit building ==
Due to a bug, versions of scons '''<=2.3''' should alter a line in:<br>
'''C:\WinPython27\WinPython-32bit-2.7.5.1\python-2.7.5\Lib\site-packages\scons-2.3.0\SCons\Tool\MSCommon\vc.py'''
Line '''364''':
<source lang="python">
if not req_target_platform and target_platform in ('amd64','x86_64'):
try_target_archs.append('x86')
</source>
Should be:
<source lang="python">
#if not req_target_platform and target_platform in ('amd64','x86_64'):
# try_target_archs.append('x86')
if target_platform in ('amd64','x86_64'):
try_target_archs.append('x86')
print "requested", req_target_platform
print "target", target_platform
print "try", try_target_archs
</source>
If not fixing the bug, you will get:
<source lang="powershell">
C:\WinPython27\relax_disp_32>scons
scons: Reading SConscript files ...
scons: done reading SConscript files.
scons: Building targets ...

</source>
= Build relax =
Open the '''WinPython Command Prompt''' <br>
Navigate to the SVN checked out relax folder.<br>
cd C:\WinPython27\relax_disp_32
scons
Or navigate to C:\WinPython27\relax_disp_32, hold "Shift" and right click, "Open command window here". Write:
pyt32
scons
== Modify pyt32.bat ==
Modify '''C:\WinPython27\WinPython-32bit-xxx\scripts\own\pyt32.bat''', and add to end of file
<source lang="powershell">
set PATH=%PATH%;C:\WinPython27\relax_disp_32
</source>
Test installation, by clicking '''C:\WinPython27\WinPython-32bit-xxx\scripts\own\cmdpyt32.bat''', and write
<source lang="powershell">
relax
relax -g
</source>
=== Tip - shortcut to cmdpyt32.bat ===
Make shortcut to '''C:\WinPython27\WinPython-32bit-xxx\scripts\own\cmdpyt32.bat''', and modify the shortcut. Set
'''Start in:''' %PWD%
You can now copy this shortcut around, which open a command prompt at the current folder, and set the paths correctly.
= Install other software =
== xmgrace - for the plotting results of NMR-relax ==
relax produces xmgrace "'.agr" files for plotting. There exist two ports for xmgrace to windows [http://sourceforge.net/projects/qtgrace/ QtGrace] and [http://sourceforge.net/projects/gracegtk/ GraceGTK].
Download [http://sourceforge.net/projects/qtgrace/ QtGrace], and unpack to '''C:\WinPython27\qtgrace_windows_binary'''. <br>
Then copy '''C:\WinPython27\qtgrace_windows_binary\bin\qtgrace.exe''' to '''C:\WinPython27\qtgrace_windows_binary\bin\xmgrace.exe'''
Modify '''C:\WinPython27\WinPython-32bit-xxx\scripts\own\pyt32.bat''', and add to end of file
<source lang="powershell">
set PATH=%PATH%;C:\WinPython27\qtgrace_windows_binary\bin
</source>
Test installation, by clicking '''C:\WinPython27\WinPython-32bit-xxx\scripts\own\cmdpyt32.bat''', and write
<source lang="powershell">
xmgrace
</source>
which should start xmgrace.
