h1. Install supporting packages

Install any missing prerequisite supporting packages by following the instructions for your specific Linux distribution.

For example, SUSE users can use YaST to install them; RedHat and CentOS users can use @yum@, Debian and Ubuntu uses @apt-get@. 

We highly recommend using pre-built binary packages to install the programs. Installing from source can quickly become a nightmare! See also the previous page, [[Instructions_for_installing_CentOS_on_your_computer]] for Red Hat based systems.

h3.  Required supporting packages:

|_.Name:|_.Download site:|_.yum package name|_.SuSE rpm name|

|Python 2.4 or newer| "http://www.python.org":http://www.python.org|python|python-devel|

|wxPython 2.5.2.8 or newer| "http://www.wxpython.org":http://www.wxpython.org|wxPython|python-wxGTK|

|MySQL Python client 1.2 or newer| "http://sourceforge.net/projects/mysql-python":http://sourceforge.net/projects/mysql-python|MySQL-python|python-mysql|

|Python Imaging Library (PIL) 1.1.4 or newer| "http://www.pythonware.com/products/pil/":http://www.pythonware.com/products/pil/|python-imaging|python-imaging|

|NumPy 1.0.1 or newer| "http://www.scipy.org":http://www.scipy.org|numpy|numpy|

|SciPy 0.5.1 (tested, others may work)*| "http://www.scipy.org":http://www.scipy.org|scipy|python-scipy|

In the past, the Python XML module was require but may not be anymore "http://pyxml.sourceforge.net/topics/":http://pyxml.sourceforge.net/topics/

h3.  Scipy/Numpy

* SciPy may not build from source properly on some versions of SuSE due to an incompatible LAPACK package that comes with SuSE. You can get scipy as well as a compatible LAPACK etc. from http://repos.opensuse.org/science (need to specify your SuSE version and machine etc.)

You can test your numpy and scipy install with their build in test functions:

<pre>

python -c 'import numpy; numpy.test(level=1)'

python -c 'import scipy; scipy.test(level=1)'

</pre>

Numpy is more stable should be successful. Expect to see lots of errors with scipy.

h3.  Mac OS X 10.5+:

You can successfully install most of these packages on a Mac by downloading DMG files and clicking on the install programs. This is not for novice Mac user.

# First, start by downloading the @Mac OS X Installer Disk Image@ (v2.6 recommended) from http://python.org/download/ and install the newer version of python

# Download and install numpy and scipy DMG files from http://sourceforge.net/projects/numpy/files/ and http://sourceforge.net/projects/scipy/files/

# Download and install wxPython DMG file from http://www.wxpython.org/download.php

Other program need more work:

# The Python Imaging Library (PIL) has be compiled from source, which also requires the "Mac OS X Developer tools":http://developer.apple.com/technologies/tools/ to be installed.
