How to install PostGIS 2.0 on Ubuntu 10.04 (lucid) from source
Prerequisites
Several components are needed, which can either be built from source or installed from pre-built packages, as shown below.
Install prerequisite packages using:
sudo apt-get install build-essential postgresql-8.4 postgresql-server-dev-8.4 libxml2-dev libproj-dev libjson0-dev xsltproc docbook-xsl docbook-mathml
Optional package for raster support (recommended):
sudo apt-get install libgdal-dev
Build GEOS 3.3.x
PostGIS 2.0 requires GEOS ≥ 3.3.2 for topology support.
There are multiple ways to build GEOS, but this is the simplest:
wget http://download.osgeo.org/geos/geos-3.3.9.tar.bz2 tar xfj geos-3.3.9.tar.bz2 cd geos-3.3.9 ./configure make sudo make install cd ..
Build PostGIS
wget http://download.osgeo.org/postgis/source/postgis-2.0.7.tar.gz tar xfz postgis-2.0.7.tar.gz cd postgis-2.0.7
PostGIS 2.0 can be configured to disable topology or raster support, using the configure flags --without-raster and --without-topology. The default is to build both:
./configure make sudo make install sudo ldconfig sudo make comments-install
Lastly, enable the command-line tools to work from your shell:
sudo ln -sf /usr/share/postgresql-common/pg_wrapper /usr/local/bin/shp2pgsql sudo ln -sf /usr/share/postgresql-common/pg_wrapper /usr/local/bin/pgsql2shp sudo ln -sf /usr/share/postgresql-common/pg_wrapper /usr/local/bin/raster2pgsql
Using enabler scripts
Enabler scripts can be used to either build a template, or directly spatially enable a database.
The following example creates a template, which can be re-used for creating multiple spatially-enabled databases. Or if you just want to make one spatially enabled database, you can modify the commands for your needs.
PostGIS:
sudo -u postgres createdb template_postgis sudo -u postgres createlang plpgsql template_postgis sudo -u postgres psql -d template_postgis -c "UPDATE pg_database SET datistemplate=true WHERE datname='template_postgis'" sudo -u postgres psql -d template_postgis -f /usr/share/postgresql/8.4/contrib/postgis-2.0/postgis.sql sudo -u postgres psql -d template_postgis -f /usr/share/postgresql/8.4/contrib/postgis-2.0/spatial_ref_sys.sql sudo -u postgres psql -d template_postgis -f /usr/share/postgresql/8.4/contrib/postgis-2.0/postgis_comments.sql
with raster support:
sudo -u postgres psql -d template_postgis -f /usr/share/postgresql/8.4/contrib/postgis-2.0/rtpostgis.sql sudo -u postgres psql -d template_postgis -f /usr/share/postgresql/8.4/contrib/postgis-2.0/raster_comments.sql
with topology support:
sudo -u postgres psql -d template_postgis -f /usr/share/postgresql/8.4/contrib/postgis-2.0/topology.sql sudo -u postgres psql -d template_postgis -f /usr/share/postgresql/8.4/contrib/postgis-2.0/topology_comments.sql
