Re: Development of the relax-disp branch. -- May 14, 2013 - 17:52

I will close this thread, and report the test-suite result for

winpython 32 bit, relax "C:\WinPython27\WinPython-32bit-2.7.4.1\relax>relax --test-suite > relax32_test-suite.txt"

winpython 64 bit, relax "C:\WinPython27\WinPython-64bit-2.7.4.1\relax>relax --test-suite > relax64_test-suite.txt"

winpython 64 bit, relax_disp "C:\WinPython27\WinPython-64bit-2.7.4.1\relax_disp>relax --test-suite > relaxdisp64_test-suite.txt"

I found that you only need to change the scons bug, if you compile 32 bit under 64 bit system.

If you have 64 bit compiler (Visual Studio Professional), you should not alter it.

I put my install notes here for reference:

-------- wiki markup ------------

= Download preparation =

First: Download these packages, do not unpack them yet.

# (.exe): wxPython: http://www.lfd.uci.edu/~gohlke/pythonlibs/#wxpython

# (.exe): scons: http://www.lfd.uci.edu/~gohlke/pythonlibs/#scons

# (.zip): minfx: http://download.gna.org/minfx/

# (.zip): bmrblib: http://download.gna.org/bmrblib/

take amd64 versions if you have a computer with 64 bit.

= 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]

To fix a current DLL error in Winpython 64 bit, you need to install

[http://www.lfd.uci.edu/~gohlke/pythonlibs/ Microsoft Visual C++ 2008 Redistributable Package (x64)].

[http://www.microsoft.com/en-us/download/details.aspx?id=15336 Download here]

Run the downloaded winpython exe file, and extract for example to: '''C:\WinPython27'''.<br>

Open '''WinPython Control Panel''' in ex. '''C:\WinPython27\WinPython-64bit-2.7.4.1'''<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-64bit-2.7.4.1''', which fixes path issues for finding python.

= Install Visual Studio Express 2012 =

[http://msdn.microsoft.com/en-us/library/vstudio/hs24szh9.aspx See versions of VS 2012 here].<br>

For 64 bit compiling, you will need, '''Visual Studio Professional''', since it has: 64-bit x64 compiler.<br>

From http://www.microsoft.com/visualstudio/eng/downloads, download and install: [http://go.microsoft.com/?linkid=9810223 Visual Studio Professional 2012 90-day trial].<br>

Skip all extra packages install. After install, just exit any program, which opened after install.

== Bugfix scons for 32bit building - ONLY do this if you have winpython 32 bit. ==

Due to a bug, versions of scons '''<=2.3''' should alter a line in:<br>

'''C:\WinPython27\WinPython-32bit-2.7.4.1\python-2.7.4\Lib\site-packages\scons-2.3.0\SCons\Tool\MSCommonvc.py'''

Line '''364''': 

 if not req_target_platform and target_platform in ('amd64','x86_64'):

Should be:

 if target_platform in ('amd64','x86_64'):

= Install Subversion checkout of relax =

Install a subversion client. For example: http://tortoisesvn.net/

Right click in winpython folder: '''C:\WinPython27\WinPython-64bit-2.7.4.1''', and select '''SVN Checkout'''. Write the path:

 svn://svn.gna.org/svn/relax/trunk

 svn://svn.gna.org/svn/relax/branches/relax_disp/

= Build relax = 

Open the '''WinPython Command Prompt''' <br>

Navigate to the SVN checked out relax folder

 cd ..\relax

 scons

 (Scons will automatically find CL.exe, and setup compilation for 64 bit.)

== Modify relax.bat ==

Copy relax.bat to relaxgui.bat

Modify relax.bat:

 32x: %~dp0\..\python-2.7.4\python "%~dp0\relax.py" %*

 64x: %~dp0\..\python-2.7.4.amd64\python "%~dp0\relax.py" %*

Modify relaxgui.bat:

 32x: %~dp0\..\python-2.7.4\python "%~dp0\relax.py" -g %*

 64x: %~dp0\..\python-2.7.4.amd64\python "%~dp0\relax.py" -g %*

= Coding editor =

A lightweight editor, could be pyscripter. <br>

This helps with syntax high-lighting and includes the interpreter. <br>

Install from: https://code.google.com/p/pyscripter/

Then download source rpyc from: https://pypi.python.org/pypi/rpyc/3.2.3 <br>

Drag (.zip) into the winpython installer <br>

To let pyscripter find python, you need to register it in the windows registry. <br>

'''Advanced->Register distribution->Yes'''

Remember to check that indention is set to equal 4 spaces "    ", under Tools/Options/Editor Options <br>

Also set: Run/Python Engine/Remote (Tk)  (Matplotlib uses the Tk) <br>

Test that everything is working, for example by this script, and hit the green play button. <br>

<pre>

from pylab import *

a = array(range(10))

b = 10*a

plot(a,b)

show()

Hi,

You got it!  The problem was the 64 vs. 32-bit mismatch.  When I
compile the MS Windows distribution package
(http://www.nmr-relax.com/download.html#MS_Windows) on 32-bit Windows
2000 with MSVS 2005 and 32-bit Python 2.7, the modules there are
32-bit.  This 32-bit module should run fine on 64-bit MS Windows
machines.  I also have a vm with 64-bit Win7 with MSVS 2010 and 64-bit
Python 2.7 where I can compile 64-bit relax modules.  Using stock MSVS
with the stock Python from http://python.org/, this compilation issue
is not encountered.

A good test would be to now check out the relax trunk and to run the
full test suite.  The trunk is kept in a state whereby the test suite
always passes (well, I try anyway).  You can run the full test suite
with:

$ relax --test-suite

For the relax trunk, this should pass.  Note that the test suite is
incredibly extensive - it can take up to 30 minutes to 1 hour to
complete on a relatively modern computer.  You will need to install
the minfx (https://gna.org/projects/minfx/) and bmrblib
(http://gna.org/projects/bmrblib/) Python modules.  These are included
within the relax distribution packages, but for the source code
repository you will need to install them as regular Python packages.
You will also need scipy and wxPython.  A second good test would be to
launch the relax GUI with:

$ relax --gui

If you do this for the relax_disp branch, you can test if you can
start a relaxation dispersion analysis.  For the relax trunk, you
could also try running the test suite again from within the GUI via
the menu system.

You may have noticed that I have updated the MS Windows development
platform webpage (http://www.nmr-relax.com/windows_devel.html) as we
have been battling this problem.  It should now be more up to date.  I
was wondering if you had HTML coding skills?  The HTML code for the
relax website is quite basic.  I was thinking that we could create a
new section for that page titled "1. Python" and then shift the
numbers of all the others down.  Then "1.1 Official Python" would
describe the installation of the stock Python for http://python.org/,
and all the 1.1.x subsections could describe the setup and
installation of the Python modules required (minfx -
https://gna.org/projects/minfx/, bmrblib -
http://gna.org/projects/bmrblib/, numpy, scipy, and wxPython).
Section "1.2 WinPython" could then describe that setup and how to
install the modules.  Section "1.3 EPD" may no longer be necessary.
We could also add a new section "2.4.4" or "3.4.4" after the
renumbering for the 64-bit vs. 32-bit compilation issue with
WinPython.  I have also modified section 4 to be about different code
editors rather than just Vim.  So your editor of choice could also be
described there, including the settings required for coding for relax.
 Most of the text from your relax.txt file (see the end of
http://thread.gmane.org/gmane.science.nmr.relax.devel/3835/focus=3854)
could be incorporated into this webpage, just modified for WinPython
rather than EPD.  For other relax users in the future, it would be
great to have this information permanently added to
http://www.nmr-relax.com/windows_devel.html.  If you would like to
help incorporate the details of your relax.txt file into this webpage,
you can check out the entire relax website with the command:

$ svn co https://svn.gna.org/svn/relax/website

Just be wary that, because SVN minimally keeps 2 copies of each file,
the entire website when checked out currently takes 1.6 Gb of disk
space.  This includes 1.5 Gb of API documentation
(http://www.nmr-relax.com/api/).

Cheers,

Edward
