3 Installation from CVS

Another variant is to download the source code of the GRASS versions 5.46.0a tarballed CVS snapshot from the GRASS Homepage (12) or directly from CVS. For the latter the CVS-needed environment variable CVSROOT has to be set. Afterwards log into the CVS server, which asks for a password and download the current source code on your computer and compile it like described in chapter 3.2.

The following example shows this for a bash-Shell:

export CVSROOT=:pserver:grass-guest@intevation.de:\
/home/grass/grassrepository
cvs login
PW is "grass"

Now, a copy of the source code can be downloaded with the following command:

cvs -z3 co grass        # for GRASS 5.4 CVS 
cvs -z3 co grass51      # for GRASS 6.0 CVS (according to 
                        # historical reasons 5.1)

Subsequently this is compiled (see Chapter 3.2).

./configure [...]
make
make install

Within the folder grass or grass51 an update of the source code can be downloaded with the following command in order to compile again:

make distclean  # Remove the already compiled parts of the source code 
cvs up -dP      # Update the source code from the CVS
