=====================
Installing SpatiaLite
=====================
`SpatiaLite`__ adds spatial support to SQLite, turning it into a full-featured
spatial database.
First, check if you can install SpatiaLite from system packages or binaries.
For example, on Debian-based distributions that package SpatiaLite 4.3+, try to
install the ``libsqlite3-mod-spatialite`` package. For older releases install
``spatialite-bin``.
For macOS, follow the :ref:`instructions below<spatialite_macos>`.
For Windows, you may find binaries on the `Gaia-SINS`__ home page.
In any case, you should always be able to :ref:`install from source
<spatialite_source>`.

Installing from source
======================
:doc:`GEOS and PROJ</ref/contrib/gis/install/geolibs>` should be installed
prior to building SpatiaLite.
SQLite
------
Check first if SQLite is compiled with the `R*Tree module`__. Run the sqlite3
command line interface and enter the following query:
.. code-block:: sqlite3
sqlite> CREATE VIRTUAL TABLE testrtree USING rtree(id,minX,maxX,minY,maxY);
If you obtain an error, you will have to recompile SQLite from source. Otherwise,
skip this section.
To install from sources, download the latest amalgamation source archive from
the `SQLite download page`__, and extract:
.. code-block:: shell
$ wget https://www.sqlite.org/YYYY/sqlite-amalgamation-XXX0000.zip
$ unzip sqlite-amalgamation-XXX0000.zip
$ cd sqlite-amalgamation-XXX0000
Next, run the ``configure`` script -- however the ``CFLAGS`` environment variable
needs to be customized so that SQLite knows to build the R*Tree module:
.. code-block:: shell
$ CFLAGS="-DSQLITE_ENABLE_RTREE=1" ./configure
$ make
$ sudo make install
$ cd ..
__ https://www.sqlite.org/rtree.html
__ https://www.sqlite.org/download.html
.. _spatialitebuild:
SpatiaLite library (``libspatialite``)
--------------------------------------
Get the latest SpatiaLite library source bundle from the
`download page`__:
.. code-block:: shell
$ wget https://www.gaia-gis.it/gaia-sins/libspatialite-sources/libspatialite-X.Y.Z.tar.gz
$ tar xaf libspatialite-X.Y.Z.tar.gz
$ cd libspatialite-X.Y.Z
$ ./configure
$ make
$ sudo make install
.. note::
For macOS users building from source, the SpatiaLite library *and* tools
need to have their ``target`` configured:
.. code-block:: shell
$ ./configure --target=macosx
__ https://www.gaia-gis.it/gaia-sins/libspatialite-sources/
.. _spatialite_macos:
macOS-specific instructions
==============================
To install the SpatiaLite library and tools, macOS users can use `Homebrew`_.
Homebrew
--------
`Homebrew`_ handles all the SpatiaLite related packages on your behalf,
including SQLite, SpatiaLite, PROJ, and GEOS. Install them like this:
.. code-block:: shell
$ brew update
$ brew install spatialite-tools
$ brew install gdal
Finally, for GeoDjango to be able to find the SpatiaLite library, add the
following to your ``settings.py``::
SPATIALITE_LIBRARY_PATH = "/usr/local/lib/mod_spatialite.dylib"
.. _Homebrew: https://brew.sh/
