→Check out a relax branch: Transclusion of the {{historical svn}} template.
How to install relax on Mac OS X systems.
== Installing the relax dependencies ==
=== Check out a relax branch ===
{{historical svn}}
You can see the different relax branches [http://svn.gna.org/viewcvs/relax/ here.]. '''Subversion''' is necessary, and should be shipped with [ http://subversion.apache.org/packages.html#osx OS X].
<source lang="bash">
cd $HOME/Downloads
</source>
To check out the relax_disp or trunk branch using the subversion client, simply type:
<source lang="bash">
svn co svn://svn.gna.org/svn/relax/trunk relax_trunk
</source>
If this svn command does not work, try:
<source lang="bash">
svn co http://svn.gna.org/svn/relax/trunk relax_trunk
</source>
<source lang="bash">
cd $HOME/Downloads/relax_trunk
# Then build
scons
</source>
=== Minfx and Bmrblib ===
<source lang="bash">
cd $HOME/Downloadscurl http://download.gna.org/minfx/minfx-1.0.5.tar.gz -o minfx-1.0.5.tar.gztar -xzf minfx-1.0.5.tar.gzcd minfx-1.0.5python setup.py installcd .. curl http://download.gna.org/bmrblib/bmrblib-1.0.3.tar.gz -o bmrblib-1.0.3.tar.gztar -xzf bmrblib-1.0.3.tar.gzcd bmrblib-1.0.3python setup.py installrelax_trunkcd ..scons

If you get the message '''-bash: gcc: command not found''', you need to install [https://developer.apple.com/xcode/ Apple Xcode].
=== Numpy ===
=== Mpi4py ===
{{note|This is for running on multi-processor machines, for the analyses in relax which support it. Download the file from the [https://code.google.com/p/mpi4py/downloads/list mpi4py download site]. <br>Note, this will require an up to date version of XCode installed on your system, as the code will be compiled.<br>}}Download the file labelled as '''mpi4py-1.x.x.tar.gz'''.<br>Open this through the Finder to unpackage the archive into the '''~/Downloads/mpi4pyThis is for running on multi-1.x.x/''' directory.<br>Open a terminal and typeprocessor machines, replacing for the x's with the current version, the following to get into the correct directory: <source lang="bash">$ cd ~/Downloads/mpi4py-1analyses in relax which support it.x.x </source><br>Then to be sure the correct Python version is being used, type:# [[Mpi4py#Install | Mpi4py]]
<source lang="bash">
$ sudo /Library/Frameworks/Python.framework/Versions/2.7/bin/python setup.py install
pip install numpy
=== Minfx and Bmrblib ===
Note that if you have multiple Python versions, the correct one must be specified. It is best to use the full Python path, for example:
>>> import wx
>>> wx.__version__; wx.__file__
'...'
>>> import bmrblib
>>> bmrblib.__version__; bmrblib.__file__
'...'
>>> import minfx
>>> minfx.__version__; minfx.__file__
'...'
