Gary,

several things:

1. The version of r.cva on my homepage was hopelessly outdated. You
would not get that to compile on a recent version of GRASS CVS.
Sorry about this. I just updated the file on my homepage. It will
from now on *only* work with GRASS 6.1 CVS. Please download that
version and try again.
I have tested it with my CVS install (ca. 4-5 days old) and it
works without problems.

2. See my comments below:

linux:/usr/localsrc/grass61cvs/extman/gem-1.0.rc5 # ./gem
--install=/usr/localsrc/grass61cvs/cva/AdvancedViewshedAnalysis.tar.gz
--grass=/usr/localsrc/grass61cvs/grass-6.1.cvs_src_snapshot_2006_06_18
Uncompressing files...DONE.
Checking extension...DONE.

WARNING: GRASS version unknown. Extension might not work after

this looks bad. Are you 100% sure that the path you have specified
with --grass= points to the install dir not the GRASS sources?
If it is the right path, then there must be a file etc/VERSIONNUMBER
which contains a single line reading:

6.1.cvs

this is the version information for your GRASS installation and GEM
needs to be able to read this file.

Make sure you have the right path.

Also, try to copy AdvancedViewshedAnalysis.tar.gz to the same

If problems persist, I need a more detailed error log in order to
be able to help you.

Do:

./gem --grass=[path] -vi [extension] &> log.txt

and email me 'log.txt'

Good luck,

Benjamin

Gary,

all you need to know is where your GRASS has been installed
when you (or whoever did the installation) did the

make install

for the CVS sources.

If the defaults weren't changed, chances are pretty high that
everything went into

/usr/local/grass-6.1.cvs

and that would be the location you have to specify with
the --grass= option.

An alternative is to first start GRASS, then use GEM
from within the GRASS shell. In that case, GEM will
figure out the install path by itself and you don't
need to give the --grass= option.

Sounds good. It's a bit late to start hacking (about 1AM on the west coast of the US), but I will give it a shot tomorrow (technically today). Moving the cva to gem is a snap. Finding those locations is tricky since it assumes you know how grass is built.

Thanks in advance for the advice.

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

I ran gem with a -v option. It looks like when I run gem, it trys to compile GRASS, which is fine with me. However, I need to pass some flags to GRASS such as -without-postgres. Is there some hook in GEM to send options to control GRASS compilation.
