Installation Manual

Step 1: Libraries installation

Compile and install PostgreSQL, PostGIS, Proj, GEOS, BGL and GAUL. Usually it is enough to execute:

# ./configure 
# make 
# make install

in corresponding directory.

If you have BGL installed but the version is less than 1.33.0, just download the astar.hpp file from  http://www.boost.org/boost/graph/astar_search.hpp and copy it to BOOST_PATH/graph directory.

For Traveling Salesperson Problem [optional]

The GAUL library should be compiled with --enable-slang=no option. Otherwise make sure you have slang.h installed in /usr/include. For more details please refer to corresponding README or INSTALL file.

# ./configure --disable-slang

For Driving Distance [optional]

For CGAL, the compile option below can be used to create the library:

# ./install_cgal --prefix=/usr --with-boost=n --without-autofind -ni /usr/bin/g++

CGAL needs special treatment!

After you install CGAL, you need to locate the directory with CGAL header files. In that directory you need to find config subdirectory. This directory contains one or more subdirectories with platform-dependent information.
It may look like this, for example:

/
|
+- usr
  |
  +- include
     |
     +- CGAL
        |
        +- config
           |
           +- i686_Linux-2.6_g++4.1.1
           |  |
           |  +- CGAL
           |     |
           |     +- compiler_config.h   <<< this is the file you need
           |
           +- msvc7
           |  |
           |  +- CGAL
           |     |
           |     +- compiler_config.h
           |
          etc...

All you need to do is to choose compiler_config.h for your platform and make a symlink or copy it to the main headers directory.
For example:

# ln -s /usr/include/CGAL/config/i686_Linux-2.6_g++4.1.1/compiler_config.h /usr/include/CGAL/compiler_config.h

Step 2: Compiling the pgRouting library

1. Get pgRouting source
2. Change to pgRouting directory
3. Compile and install pgRouting

• For pgRouting core (required)

  cmake .
  make
  make install
  

• For pgRouting extras (optional)

  # Add Traveling Salesperson functionality:  -DWITH_TSP=ON
  # Add Driving Distance functionality     :  -DWITH_DD=ON
  
  cmake -DWITH_TSP=ON -DWITH_DD=ON .
  make
  make install
  

If your program compiles but you get an error like the following one:

error while loading shared libraries: libgaul.so.0: cannot open shared object file: No such file or directory

1. Add the library path (ie. /usr/local/pgsql/lib) to /etc/ld.co.conf
2. Run ldconfig

Maybe you installeb PostgreSQL from Source-code, while compiling pgRouting you might get an error like

  Output directory for libraries is set to sh: pg_config: command not found 
  ....
  ....ERROR: could not access file "$libdir/librouting

Then you need to type at the shell-console:

  export PATH="$PATH:/usr/local/pgsql/bin"

....presuming you installed PostgreSQL at /usr/local/pgsql/bin

Step 3: Create a routing database and load PostGIS and pgRouting functions

1. Create a routing database and load PostGIS

   createdb -U postgres -E UNICODE routing
   createlang -U postgres plpgsql routing
   
   psql -U postgres -f /path/to/postgis/lwpostgis.sql routing
   psql -U postgres -f /path/to/postgis/spatial_ref_sys.sql routing
   

2. Add pgRouting core functions (required)

   psql -U postgres -f /usr/share/postlbs/routing_core.sql routing
   psql -U postgres -f /usr/share/postlbs/routing_core_wrappers.sql routing
   

3. Add pgRouting extra functions (optional)

   # With TSP
   psql -U postgres -f /usr/share/postlbs/routing_tsp.sql routing
   psql -U postgres -f /usr/share/postlbs/routing_tsp_wrappers.sql routing
   
   # With Driving Distance
   psql -U postgres -f /usr/share/postlbs/routing_dd.sql routing
   psql -U postgres -f /usr/share/postlbs/routing_dd_wrappers.sql routing
