Installation mac mavericks os x

Installation

Download a python distribution which include wxPython

At the time for this post, (Dec 2013), the installation of wxPython2.9-osx-cocoa-py2.7 made hickups and crashes.
This is reported here and here.

The problem is based on the wxPython version and 32/64 bit issues.
It is therefore strongly recommended to install the 32 bit python package distribution.

If one installs the "epd" enthought python distribution, this will include a working wxPython.
SIgn-up with preferably a university email to get the Academic License, and you can then download for free https://www.enthought.com/repo/epd/installers/

Specifically download and install:
epd-7.x-x-macosx-i386.dmg

Special note about 64-bit Mac OSX

The macosx-x86_64 installer does not include wxPython, which a lot of ETS relies on. Even though ETS supports the use of PySide as a backend, things are much less stable under Qt. Therefore, if you want to use ETS, we recommned using the 32-bit EPD on Mac OSX.

Testing the Python installation

After installation, restart your terminal, and check path to python.

$ which python
/Library/Frameworks/Python.framework/Versions/Current/bin/python

Before installing relax, it is best to be sure that the Python modules are functional by trying to import them and print the version of them:

$ python
Enthought Python Distribution -- www.enthought.com
Version: 7.3-2 (32-bit)

Python 2.7.3 |EPD 7.3-2 (32-bit)| (default, Apr 12 2012, 11:28:34) 
[GCC 4.0.1 (Apple Inc. build 5493)] on darwin
Type "credits", "demo" or "enthought" for more information.

>>> import wx; wx.__version__; wx.__file__
'2.8.10.1'
'/Library/Frameworks/Python.framework/Versions/7.3/lib/python2.7/site-packages/wx/__init__.py'

Then install pip

$ sudo easy_install pip

Minfx and Bmrblib

Remember to check, if there are newer versions of minfx and bmrblib.
The minfx and bmrblib libraries can be installed on all Linux systems by typing:

cd $HOME/Downloads
curl http://download.gna.org/minfx/minfx-1.0.5.tar.gz -o minfx-1.0.5.tar.gz
tar -xzf minfx-1.0.5.tar.gz
cd minfx-1.0.5
sudo pip install .
cd ..

curl http://download.gna.org/bmrblib/bmrblib-1.0.3.tar.gz -o bmrblib-1.0.3.tar.gz
tar -xzf bmrblib-1.0.3.tar.gz
cd bmrblib-1.0.3
sudo pip install .
cd

Then check

$ python
Enthought Python Distribution -- www.enthought.com
Version: 7.3-2 (32-bit)

Python 2.7.3 |EPD 7.3-2 (32-bit)| (default, Apr 12 2012, 11:28:34)

import bmrblib; bmrblib.__version__; bmrblib.__file__
'1.0.3'
'/Library/Frameworks/Python.framework/Versions/7.3/lib/python2.7/site-packages/bmrblib/__init__.pyc'

import minfx; minfx.__version__; minfx.__file__
'1.0.5'
'/Library/Frameworks/Python.framework/Versions/7.3/lib/python2.7/site-packages/minfx/__init__.pyc'

Check if the have been installed

pip freeze | grep "minfx\|bmrblib"

Checking out a relax branch and build with scons

If you would like to play with relax branch rather than the main relax downloads, the Subversion program should first be installed.
You can see the different branches here.
First the relax sources can be checked out of the source code repository and the C modules compiled:

Using subversion or git

To check out the trunk branch using the subversion client, simply type:

svn co svn://svn.gna.org/svn/relax/trunk relax_trunk

If this svn command does not work, try:

svn co http://svn.gna.org/svn/relax/trunk relax_trunk

Compilation of the C modules

For the R1 and R2 and relaxation dispersion analyses, the relax C modules must be compiled. This is done using the scons program, by simply typing:

cd relax_trunk

SEARCH="'i386', 'ppc', 'x86_64'"
REPLACE="'i386', 'x86_64'"

mv sconstruct sconstruct_bck
cat sconstruct_bck | sed -e "s/$SEARCH/$REPLACE/"  > sconstruct
scons

Install brew as 'linux' package manager

You can read about brew here.
In short, it is like a package manager for mac, where you will be able to get linux programs to mac.

 ruby -e "$(curl -fsSL https://raw.github.com/mxcl/homebrew/go/install)"

Install xmgrace

xmgrace is used for plotting.

brew install xmgrace
