Introduction

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
