[GRASS-dev] Re: [GRASS-user] CVA installation

[Benjamin Ducke]

Gary,

GEM does not compile GRASS. It compiles the source code for
r.cva which is structured much like GRASS, so it looks very similar
on screen. It then installs the compiled r.cva into the same
directory where your GRASS was installed.
You should not have to pass any compile-time options, as your
GRASS capabilities will not be touched.

Does the configuration abort with an error if you don't have
postgresql installed?

Best,

Benjamin
