# Development install on windows¶

## The easy way - a super-package¶

The easiest way to get the dependencies is to install PythonXY or the Enthought Tool Suite . This gives you MinGW, Python, Numpy, Scipy, ipython and matplotlib (and much more).

## The hard way - by components¶

If instead you want to do it by component, try the instructions below.

Requirements:

Options:

Alternatively, if you are very brave, you may want to install numpy / scipy from source - see our maybe out of date Building Scipy/Numpy on Windows with Optimized Numerical Libraries for details.

## Getting and installing NIPY¶

You will next need to get the NIPY code via version control:

• Go to the windows menu, find the git menu, and run git in a windows terminal.

You should now be able to follow the instructions in Submitting a patch, but with the following modifications:

## Running the build / install¶

Here we assume that you do not have the Microsoft visual C tools, you did not use the ETS package (which sets the compiler for you) and are using a version of MinGW to compile NIPY.

First, for the python setup.py steps, you will need to add the --compiler=mingw32 flag, like this:

python setup.py build --compiler=mingw32 install


Note that, with this setup you cannot do inplace (developer) installs (like python setup.py build_ext --inplace) because of a six-legged python packaging feature that does not allow the compiler options (here --compiler=mingw32) to be passed from the build_ext command.

If you want to be able to do that, add these lines to your distutils.cfg file

[build]
compiler=mingw32

[config]
compiler = mingw32


See http://docs.python.org/install/#inst-config-files for details on this file. After you’ve done this, you can run the standard python setup.py build_ext --inplace command.

### The command line from Windows¶

The default windows XP command line cmd is very basic. You might consider using the Cygwin bash shell, or you may want to use the ipython shell to work in. For system commands use the ! escape, like this, from the ipython prompt:

!python setup.py build --compiler=mingw32
