Instructions for downloading and installing binaries for different operating systems, additional notes and corrections not included in this documentation can be found in Installation wiki

To use pgRouting PostGIS needs to be installed, please read the information about installation in this Install Guide

Short Version

Extracting the tar ball

tar xvfz pgrouting-3.4.2.tar.gz
cd pgrouting-3.4.2

To compile assuming you have all the dependencies in your search path:

mkdir build
cd build
cmake  ..
make
sudo make install

Once pgRouting is installed, it needs to be enabled in each individual database you want to use it in.

createdb routing
psql routing -c 'CREATE EXTENSION PostGIS'
psql routing -c 'CREATE EXTENSION pgRouting'

Get the sources

The pgRouting latest release can be found in https://github.com/pgRouting/pgrouting/releases/latest

wget

To download this release:

wget -O pgrouting-3.4.2.tar.gz    https://github.com/pgRouting/pgrouting/archive/v3.4.2.tar.gz

Go to Short Version for more instructions on extracting tar ball and compiling pgRouting.

git

To download the repository

git clone git://github.com/pgRouting/pgrouting.git
cd pgrouting
git checkout v3.4.2

Go to Short Version for more instructions on compiling pgRouting (there is no tar ball involved while downloading pgRouting repository from GitHub).

Enabling and upgrading in the database

Enabling the database

pgRouting is a PostgreSQL extension and depends on PostGIS to provide functionalities to end user. Below given code demonstrates enabling PostGIS and pgRouting in the database.

CREATE EXTENSION postgis;
CREATE EXTENSION pgrouting;

Checking PostGIS and pgRouting version after enabling them in the database.

SELECT PostGIS_full_version();
SELECT * FROM pgr_version();

Upgrading the database

To upgrade pgRouting in the database to version 3.4.2 use the following command:

ALTER EXTENSION pgrouting UPDATE TO "3.4.2";

More information can be found in https://www.postgresql.org/docs/current/sql-createextension.html

Example: Installing dependencies on linux

Installing the compilation dependencies

Database dependencies

sudo apt install postgresql-14
sudo apt install postgresql-server-dev-14
sudo apt install postgresql-14-postgis

Configuring PostgreSQL

Entering psql console

sudo systemctl start postgresql.service
sudo -i -u postgres
psql

To exit psql console

q

Entering psql console directly without switching roles can be done by the following commands

sudo -u postgres psql

Then use the above given method to exit out of the psql console

Checking PostgreSQL version

psql --version

or

Enter the psql console using above given method and then enter

SELECT VERSION();

Creating PostgreSQL role

sudo -i -u postgres
createuser --interactive

or

sudo -u postgres createuser --interactive

Default role provided by PostgreSQL is postgres. To create new roles you can use the above provided commands. The prompt will ask the user to type name of the role and then provide affirmation. Proceed with the steps and you will succeed in creating PostgreSQL role successfully.

To add password to the role or change previously created password of the role use the following commands

ALTER USER <role name> PASSWORD <password>

To get additional details on the flags associated with createuser below given command can be used

man createuser

Creating Database in PostgreSQL

sudo -i -u postgres
createdb <database name>

or

sudo -u postgres createdb <database name>

Connecting to a PostgreSQL Database

Enter the psql console and type the following commands

connect <database name>

Build dependencies

sudo apt install cmake
sudo apt install g++
sudo apt install libboost-graph-dev

Optional dependencies

For documentation and testing

pip install sphinx
pip install sphinx-bootstrap-theme
sudo apt install texlive
sudo apt install doxygen
sudo apt install libtap-parser-sourcehandler-pgtap-perl
sudo apt install postgresql-14-pgtap

Configuring

pgRouting uses the cmake system to do the configuration.

The build directory is different from the source directory

Create the build directory

$ mkdir build

Configurable variables

To see the variables that can be configured

$ cd build
$ cmake -L ..

Configuring The Documentation

Most of the effort of the documentation has been on the HTML files. Some variables for building documentation:

Variable

Default

Comment

WITH_DOC

BOOL=OFF

Turn on/off building the documentation

BUILD_HTML

BOOL=ON

If ON, turn on/off building HTML for user’s documentation

BUILD_DOXY

BOOL=ON

If ON, turn on/off building HTML for developer’s documentation

BUILD_LATEX

BOOL=OFF

If ON, turn on/off building PDF

BUILD_MAN

BOOL=OFF

If ON, turn on/off building MAN pages

DOC_USE_BOOTSTRAP

BOOL=OFF

If ON, use sphinx-bootstrap for HTML pages of the users documentation

Configuring cmake to create documentation before building pgRouting

$ cmake -DWITH_DOC=ON -DDOC_USE_BOOTSTRAP=ON ..

Note

Most of the effort of the documentation has been on the html files.

Building

Using make to build the code and the documentation

The following instructions start from path/to/pgrouting/build

$ make          # build the code but not the documentation
$ make doc      # build only the user's documentation
$ make all doc  # build both the code and the user's documentation
$ make doxy     # build only the developer's documentation

We have tested on several platforms, For installing or reinstalling all the steps are needed.

Warning

The sql signatures are configured and build in the cmake command.

MinGW on Windows

$ mkdir build
$ cd build
$ cmake -G"MSYS Makefiles" ..
$ make
$ make install

Linux

The following instructions start from path/to/pgrouting

mkdir build
cd build
cmake  ..
make
sudo make install

To remove the build when the configuration changes, use the following code:

rm -rf build

and start the build process as mentioned previously.

Testing

Currently there is no make test and testing is done as follows

The following instructions start from path/to/pgrouting/

tools/testers/doc_queries_generator.pl
createdb -U <user> ___pgr___test___
sh ./tools/testers/pg_prove_tests.sh <user>
dropdb -U <user> ___pgr___test___
