= How to install PostGIS 2.0 on Debian 6.0 (''squeeze'') from source = == Prerequisites == Several components are needed, which can either be built from source or installed from pre-built packages, as shown below. It is assumed you have already installed and configured `sudo` (not done by default). 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-2.0.3.tar.gz tar xfz postgis-2.0.4.tar.gz cd postgis-2.0.4 }}} PostGIS 2.0 can be configured to disable topology or raster extensions, using the configure flags `--without-raster` and `--without-topology`. The default is to build both extensions: {{{ ./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. Log-in as `postgres` from `root` using "`su - postgres`", and use the following commands. Install PostGIS: {{{ createdb template_postgis createlang plpgsql template_postgis psql -d template_postgis -c "UPDATE pg_database SET datistemplate=true WHERE datname='template_postgis'" psql -d template_postgis -f /usr/share/postgresql/8.4/contrib/postgis-2.0/postgis.sql psql -d template_postgis -f /usr/share/postgresql/8.4/contrib/postgis-2.0/spatial_ref_sys.sql psql -d template_postgis -f /usr/share/postgresql/8.4/contrib/postgis-2.0/postgis_comments.sql }}} with raster support: {{{ psql -d template_postgis -f /usr/share/postgresql/8.4/contrib/postgis-2.0/rtpostgis.sql psql -d template_postgis -f /usr/share/postgresql/8.4/contrib/postgis-2.0/raster_comments.sql }}} with topology support: {{{ psql -d template_postgis -f /usr/share/postgresql/8.4/contrib/postgis-2.0/topology.sql psql -d template_postgis -f /usr/share/postgresql/8.4/contrib/postgis-2.0/topology_comments.sql }}}
