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

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

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

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

First you need to install pycairo locally:

bin/buildout -vvvvvNc cairo.cfg

Then run buildout:

bin/buildout -vvvvvN

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

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.

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
