How to get RHESSys
Getting the source
The source for RHESSys and various tools for use with RHESSys is hosted on sourceforge and
accessible via anonymous subversion access. For the latest stable release, check out
$> svn co https://rhessys.svn.sourceforge.net/svnroot/rhessys/tags/5.14.4
For the latest development version, check out
$> svn co https://rhessys.svn.sourceforge.net/svnroot/rhessys/trunk/
These are instructions for installing the GRASS 6.4 binary, RHESSys, and R on Mac OS X. (There may be differences on Linux or a virtual machine, but hopefully the procedures will be the same/similar, or users of these other platforms can find the installation information to aid them.) In order to install certain RHESSys programs (g2w and CF), GRASS libraries and header files must first be installed, therefore, you must first install GRASS.
Locating GRASS GISBASE
OS X
If you are running GRASS from the application folder, your GISBASE will be /Applications/<GRASS application name>/Contents/MacOS. For example, if your GRASS application was named GRASS-6.4, you would type the command:
$> export GISBASE=/Applications/GRASS-6.4.app/Contents/MacOS
Linux
Windows
Building RHESSys
The RHESSys source tree contains three separate tools: rhessys, cf, and g2w. Note that default values
are specified in the makefiles. This means if you choose to override them you must specify the
-e option when running make. As a convenience there is a makefile at the trunk
of the source tree that will build and install all RHESSys programs. Before running that file, make sure that
you have set all necessary environment variables as listed below.
