|
Self-contained IPython installation with all dependencies
|
|
|
===========================================================
|
|
|
|
|
|
This is a self-contained source distribution of IPython with all its
|
|
|
*non-graphical* dependencies, that installs in a single ``make`` call to your
|
|
|
home directory (by default) or any location of your choice.
|
|
|
|
|
|
This distribution is meant for developer-type usage in Unix environments, it is
|
|
|
*not* an easy way to get IPython working on Windows, since it assumes the
|
|
|
presence of a working compiler and development tools.
|
|
|
|
|
|
Currently, the distribution contains::
|
|
|
|
|
|
ipython-0.9.1.tar.gz
|
|
|
pyOpenSSL-0.6.tar.gz
|
|
|
zope.interface-3.4.1.tar.gz
|
|
|
Twisted-8.1.0.tar.bz2
|
|
|
foolscap-0.3.1.tar.gz
|
|
|
nose-0.10.3.tar.gz
|

|
Usage
|
|
|
=====
|
|
|
|
|
|
Download the single tarball where this README file lives and unpack it. If
|
|
|
your system is already configured as described below, these lines will do the
|
|
|
whole job::
|
|
|
|
|
|
wget http://ipython.scipy.org/dist/alldeps/ipython-alldeps-0.9.1.tar
|
|
|
tar xf ipython-alldeps-0.9.1.tar
|
|
|
cd ipython-alldeps-0.9.1
|
|
|
make
|
|
|
|
|
|
If all goes well, then just type::
|
|
|
|
|
|
iptest
|
|
|
|
|
|
to run IPython's test suite.
|
|
|
|
|
|
|
|
|
It is meant to be used in an environment where you have your ``$PATH``,
|
|
|
``$PYTHONPATH``, etc variables properly configured, so that the installation of
|
|
|
packages can be made with (using ``~/usr/local`` as an example)::
|
|
|
|
|
|
python setup.py install --prefix=~/usr/local
|
|
|
|
|
|
For an explanation of how to do this, see below.
|
|
|
|
|
|
You can configure the default prefix used by editing the file
|
|
|
``pkginstall.cfg``, where you can also override the python version used for the
|
|
|
process. If your system is configured in this manner, you can simply type::
|
|
|
|
|
|
make
|
|
|
|
|
|
and this will build and install all of IPython's non-graphical dependencies on
|
|
|
your system, assuming you have Python, a compiler, the Python headers and the
|
|
|
SSL headers available.

Environment configuration
|
|
|
=========================
|
|
|
|
|
|
Below is an example of what to put in your ``~/.bashrc`` file to configure your
|
|
|
environment as described in this document, in a reasonably portable manner that
|
|
|
takes 64-bit operating systems into account::
|
|
|
|
|
|
# For processor dependent config
|
|
|
MACHINE=$(uname -m)
|
|
|
|
|
|
# Python version information
|
|
|
PYVER=$(python -ESV 2>&1)
|
|
|
PYVER_MINOR=${PYVER#Python }
|
|
|
PYVER_MAJOR=${PYVER_MINOR:0:3}
|
|
|
|
|
|
function export_paths {
|
|
|
# Export useful paths based on a common prefix
|
|
|
|
|
|
# Input: a path prefix
|
|
|
|
|
|
local prefix=$1
|
|
|
local pp
|
|
|
local lp
|
|
|
local pypath=python${PYVER_MAJOR}/site-packages
|
|
|
|
|
|
# Compute paths with 64-bit specifics
|
|
|
if [[ $MACHINE == "x86_64" ]]; then
|
|
|
lp=$prefix/lib64:$prefix/lib
|
|
|
pp=$prefix/lib64/$pypath:$prefix/lib/$pypath
|
|
|
else
|
|
|
lp=$prefix/lib
|
|
|
pp=$prefix/lib/$pypath
|
|
|
fi
|
|
|
|
|
|
# Set paths based on given prefix
|
|
|
export PATH=$prefix/bin:$PATH
|
|
|
export CPATH=$prefix/include:$CPATH
|
|
|
export LD_LIBRARY_PATH=$lp:$LD_LIBRARY_PATH
|
|
|
export LIBRARY_PATH=$lp:$LIBRARY_PATH
|
|
|
export PYTHONPATH=$pp:$PYTHONPATH
|
|
|
}
|
|
|
|
|
|
# Actually call the export function to set the paths. If you want more than
|
|
|
# one such prefix, note that the call *prepends* the new prefix to the
|
|
|
# existing paths, so later calls take priority.
|
|
|
|
|
|
export_paths $HOME/usr/local
|
