GRASS

The GRASS support can be added to GDAL in two ways:

• as a built-in GRASS driver
• as a loadable GRASS driver plugin

Note, following instructions apply to Linux and other environments where GNU autotools are available (autoconf, automake, make).

Prerequisites

• Download and install ​GRASS together with development files (headers and libraries). The easiest option is to use binary packages prepared for your Linux distribution.

• Download latest stable or development version of GDAL sources:

tar -zxf gdal-1.4.1.tar.gz
cd gdal-1.4.1

Building GDAL with built-in GRASS driver

• Configure GDAL sources with GRASS support included:

./configure --with-grass=/usr/local/grass

and after ./configure finishes its job, you should see the GRASS driver enabled in the summary, like here:

GDAL is now configured for i686-pc-linux-gnu
...
  GRASS support:             grass57+
...

• Build and install GDAL:

make
make install

running last step with root privileges.

• Now, you can verify if GRASS support is enabled correctly:

./gdalinfo --formats | grep GRASS
  GRASS (ro): GRASS Database Rasters (5.7+)

./ogrinfo --formats | grep GRASS
  -> "GRASS" (readonly)

Building GDAL and GRASS driver plugin

• Configure GDAL sources without GRASS support:

./configure --without-grass

and then you should see the built-in GRASS driver disabled (no) in the summary:

GDAL is now configured for i686-pc-linux-gnu
...
  GRASS support:             no
...

• Build and install GDAL:

make
make install

Build GRASS plugin

• ​Download latest sources of GRASS plugin where the package file name is gdal-grass-X.Y.Z.tar.gz, ie. ​gdal-grass-1.4.1.tar.gz. Unpack the source package:

tar -zxf gdal-grass-1.4.1.tar.gz
cd gdal-grass-1.4.1

• Configure the plugin providing paths to gdal-config program and GRASS files as follows:

./configure --with-gdal=/usr/local/bin/gdal-config --with-grass=/usr/local/grass

• Now, the plugin is ready to build and install:

make
make install

The last step needs root privileges.
