Quick Start
-----------
## Quick Start
For platform specific install guides see:
To configure and build mapnik do:
http://trac.mapnik.org/wiki/MapnikInstallation
./configure
make
sudo make install
Install needed dependencies::
If you need to uninstall do:

Configure the build setup::
For more details see the 'Building' Section below.
$ python scons/scons.py configure
Platform specific install guides at http://trac.mapnik.org/wiki/MapnikInstallation
Build Mapnik source code::
$ python scons/scons.py
Install Mapnik library and python bindings::
$ sudo python scons/scons.py install
If on Linux then run:
$ sudo ldconfig
Run python interpreter and check installation::
>>> import mapnik
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
ImportError: No module named mapnik
>>>
If you get this error ensure that Mapnik in is your PYTHONPATH.
Otherwise your setup is ready. You can now visit

Prerequisites
-------------
## Depends
First, here is a quick list of the required software dependencies:
Mapnik is cross platform and runs on Linux, Mac OSX, Solaris, *BSD, and Windows.
- Linux/UNIX with g++ compiler
- Python 2.2 or greater to build Mapnik
- Python 2.4 for python bindings (see below)
- libboost >= 1.41.0 or greater with the following libraries included:
- system
- thread
The build system should work for all posix/unix systems but for windows see:
http://trac.mapnik.org/wiki/BuildingOnWindows
Build dependencies are:
* C++ compiler (like g++ or clang++)
* Python >= 2.4
* >= 2 GB RAM
Mapnik Core depends on:
* Boost >= 1.42.x (>= 1.45.x if using clang++) with these libraries:
- filesystem
- system
- thread (if mapnik threadsafe support is required, default on)
- regex (optionally built with icu regex support)
- python - required only for python bindings (see below)
- libicu >= 4.0 - International Components for Unicode
- libpng - PNG Graphics
- libjpeg - JPEG Graphics
- libtiff - TIFF Graphics
- libz - Compression
- libfreetype2 - Font support (Install requires freetype-config)
- libxml2 - XML parsing (Install requires xml2-config)
- proj - PROJ.4 Projection library
- program_options (optionally for mapnik command line programs)
Second, here are the optional software dependencies:
* libicuuc >= 4.0 (ideally >= 4.2) - International Components for Unicode
* libpng >= 1.2.x - PNG Graphics
* libjpeg - JPEG Graphics
* libtiff - TIFF Graphics
* libz - Zlib Compression
* libfreetype - Freetype2 for Font support (Install requires freetype-config)
* libxml2 - XML parsing (Install requires xml2-config)
* libproj - PROJ.4 Projection library
- Python 2.4 or greater for Python language bindings
- Boost 'python', required for binding Python language bindings
- Boost 'program_options' for shapeindex executable support
- Cairo - Graphics library for PDF, PS, and SVG formats
Mapnik Python binding depend on:
* Python >= 2.4
* Boost python
Optional dependencies:
* Cairo - Graphics library for PDF, PS, and SVG formats
- pkg-config - Required for building with cairo support
- libsigc++ - C++ support for cairomm
- cairomm - C++ bindings for cairo
- pycairo - Python bindings for cairo
- libpq - PostgreSQL libraries (For PostGIS plugin support)
- libgdal - GDAL/OGR input (For gdal and ogr plugin support)
- libsqlite3 - SQLite input (needs RTree support) (sqlite plugin support)
- libocci - Oracle input plugin support
- libcurl - OSM input plugin support
If your system does NOT have one of these installed, you will need to
install the mandatory ones at the very least before proceeding further.
* libpq - PostgreSQL libraries (For PostGIS plugin support)
* libgdal - GDAL/OGR input (For gdal and ogr plugin support)
* libsqlite3 - SQLite input (needs RTree support) (sqlite plugin support)
* libocci - Oracle input plugin support
* libcurl - OSM input plugin support
Instructions for installing many of these dependencies on
various platforms can be found at the Mapnik Community Wiki
(http://trac.mapnik.org/wiki/MapnikInstallation).
On Linux and Mac OS, package management systems (such as apt for debian
or macports for darwin) can be used to install most or all dependencies,
but source installs may be preferrable. This is particularly true for
libraries that a required for the Python bindings, where source installs
may be the best way to ensure that the same python version us linked to
Boost, Cairo, and Mapnik.
Note: a minimum of 256MB of RAM is recommended for the build process.
Building
--------
## Building
Once you've installed the required software packages, the simplest way to
build Mapnik is to run SCons (The software builder) without any options::
The build system uses SCons, a pure python equivalent to autotools or cmake.
$ cd ~/src/mapnik
$ python scons/scons.py configure
$ python scons/scons.py # will build sources
We provide a simple Makefile wrapper that can be used like:
This should compile and link the mapnik library as well as the input
plugins and the python language binding (if possible). If any mandatory
dependencies are not found the build will fail, and you will need to
specify custom paths to your libraries and include files.
./configure && make && make install
SCons accepts a variety of options to customize your build. This allows
you to specify which components are compiled, where to find dependencies,
where to install mapnik, and so on.
To interact with the local copy of scons directly you can do:
To see the list of available options, from the root of the source
distribution, run::
python scons/scons.py configure
$ python scons/scons.py -h
You can also use a globally installed scons:
For example, if you compiled your own set of Boost libraries, you might use::
scons configure
$ python scons/scons.py configure BOOST_INCLUDES=/usr/local/include/ BOOST_LIBS=/usr/local/lib
If you want to clean your build do:
Or if you installed ICU from source and you'd like to build Mapnik in
Debug mode you might use::
make clean
$ python scons/scons.py configure DEBUG=True ICU_INCLUDES=/usr/local/include ICU_LIBS=/usr/local/lib
If you experience odd configure errors, try resetting the SCons caches:
make reset
To install in a custom location do:
./configure PREFIX=/opt/mapnik
To pass custom CXXFLAGS or LDFLAGS do:
./configure CUSTOM_CXXFLAGS="-g -I/usr/include" CUSTOM_LDFLAGS="-L/usr/lib"
To pass custom paths to a dependency, like boost, do:
./configure BOOST_INCLUDES=/opt/boost/include BOOST_LIBS=/opt/boost/lib
To pass custom paths to a dependency, like icu, do:
./configure ICU_INCLUDES=/usr/local/include ICU_LIBS=/usr/local/include
If you want to see configure options do:
./configure --help
For more details on all the options see:
http://trac.mapnik.org/wiki/UsingScons
Note: the Python used to run SCons does NOT have to be the same as the
one used for the python bindings.
Installation
------------
Once the build has successfully completed, you can install the various
files on your system by executing::
$ sudo python scons/scons.py install
By default, everything will be installed under the PREFIX '/usr/local'
as such::
$PREFIX/lib: libmapnik.so (.dylib on mac os)
$PREFIX/lib/mapnik/input: input plug-ins
$PREFIX/include: mapnik include files
$PREFIX/bin: shapeindex utility
$PYTHON_PREFIX/lib/python$PYTHON_VERSION/site-packages/mapnik: Python bindings
If you're using the default PREFIX, you will most likely need to be root
to perform the install.
Testing Installation

A note on projection support
----------------------------
Mapnik's core C++ library and map rendering engine support on-the-fly
cartographic reprojections.
Here is an example on how to use it::
>>> import mapnik
>>> p = mapnik.Projection('+init=epsg:27700') # British National Grid
>>> p.forward(mapnik.Coord(-1.125,51.75))
Coord(460396.920899,206113.214203) # reprojected coordinate x, y pair
>>> p.forward(mapnik.Envelope(-1.125,51.75,-1.0,50.75))
Envelope(461721.365661,94917.0749406,469024.861457,206224.090767) # reprojected extent
The Projection() instance provides inverse() and forward() methods.
For details on the possible parameters, see the PROJ.4 documentation.
