==========================
Introduction
==========================

.. contents::

Official mapnik bindings repackaged in the distutils way to facilitate deployments.

This depends of those libraries to be installed on you environment:

- mapnik2 (the c++ library)
- BOOST c++:

- boost python
- boost thread
- boost regex

Optionnal but heavily recommended python libraries

- pycairo
- PIL / Pillow

If you are a buildout user, you can look at this package
buildout which integrates pycairo & pil installation

See `github `_

MAPNIK2 Notes
===============

The python bindings are tied to the mapnik2 library version.

To use with:

- :mapnik2 library - 2.0.1: == mapnik2 2.0.1.3
::

easy_install -U mapnik2==2.0.1.3

- :mapnik2 library - 2.1.0: == mapnik2 2.1.0
::

easy_install -U mapnik2==2.1.0

- :mapnik2 library - 2.2.0: == mapnik2 2.2.0
::

easy_install -U mapnik2==2.2.0

Installation
======================================
Prerequisites
-------------------
Don't forget that you can play with LDFLAGS/CFLAGS/LD_LIBRARY_PATH dto indicate non standart locations for the following requirements if it applies.

You will have to have the includes and libraries for

- The mapnik-config utility to be in your $PATH
- Boost_python linked to your python interpreter
If it is not installed in standart envionments, you ll have to handle the CFLAGS/LDFLAGS to find it, or use minitage ;)
- cairo / cairomm (optionnal but enabled if you compiled mapnik with cairo support)
- mapnik2
- The current python interpreter
- pycairo / PIL in the PYTHONPATH somehow

Buildout
----------
Some developers use buildout_ to ease deployments.
* Say where to find mapnik-config by settings correctly your PATH environment variable
* Add ``mapnik`` to the list of eggs to install, e.g.
::

[buildout]
parts = somepart

[somepart]
recipe = minitage.recipe.scripts # or zc.recipe.egg ...
eggs = mapnik2

* Re-run buildout, e.g. with::

$ ./bin/buildout

You can read the buildout installation shipped with this egg for inspiration of how integrate mapnik in a buildout.
The magic is using buildout.minitagificator to feed PKG_CONFIG_PATH and PYTHONPATH with pycairo

Running this package buildout
--------------------------------
First you need to install pycairo locally::

bin/buildout -vvvvvNc cairo.cfg

Then run buildout::

bin/buildout -vvvvvN

Easy_install with or without virtualenv
---------------------------------------------
::

virtualenv --no-site-packages test
source test/bin/activate
easy_install mapnik2

* Say where to find mapnik-config by settings correctly your PATH environment variable
* When you're reading this you have probably already run
``easy_install mapnik2``. Find out how to install setuptools
(and EasyInstall) here:
http://peak.telecommunity.com/DevCenter/EasyInstall

BOOST NOTES
--------------

To specify which boostpython lib to link against, you can use, you can use the following::

export MAPNIK2_BOOST_PYTHON="libboost_python.so.1:libboost_thread.so.1"

Where you have on your filesystem::

/usr/lib/libboost_python.so.1
/usr/lib/libboost_thread.so.1

For ubuntu users, please refer to `this doc `_ to install the prerequisites of this egg.

Minitage
--------------
Some developers use minitage_ to ease deployments (a layer upon buildout).
Indeed, it takes care a lot of things like those boring compilation flags.
As an example, to work on this egg in development mode, you can boostrap it by doing this::
::

easy_install -U virtualenv
virtualenv --no-site-packages --distribute ~/minitage
mkdir ~/minitage/others

Install minitage, if you haven't yet ::

source ~/minitage/bin/activate
easy_install -U minitage.core

Initialize it (**mandatory**) ::

source ~/minitage/bin/activate
minimerge -s

To install the minilay for the mapnik2 egg development you can do
::

cd ~/minitage/others
git clone https://github.com/mapnik/pymapnik2.git mapnik-egg-(py26 or py27)
ln -fs ~/minitage/others/mapnik-egg*/minilays/mapnik-egg/ ~/minitage/minilays/mapnik-egg
#for python-2.6
minimerge -av mapnik-egg-py26
#for python-2.7
minimerge -av mapnik-egg-py27

Enjoy your installation
::

cd ~/minitage/others/mapnik-egg-py26
or cd ~/minitage/others/mapnik-egg-py27
./bin/mypy
>>> import mapnik2

For using mapnik2 inside your minitagified application:

- Inside the eggs parts of you buildout add::

[part]
eggs += mapnik2

- In your minibuild, merge the mapnik2 dependencies that you can find here:

- for python2.6: https://github.com/mapnik/pymapnik2/blob/master/minilays/mapnik-egg/mapnik-egg-py26
- for python2.7: https://github.com/mapnik/pymapnik2/blob/master/minilays/mapnik-egg/mapnik-egg-py27

- Reminimerge your project to build the mapnik2 egg
- Then add mapnik2 to your setup.py or buildout for it to be grabbed in your pythonpath.
- Rerun buildout, you're done
