No; it's a bug in lib/gmath/Makefile, which should have $(MATHLIB) in
the definition of EXTRA_LIBS.

$(MATHLIB) (typically -lm) will usually get pulled in anyhow (e.g. via
$(FFTWLIB)), hence the reason that no-one has noticed this before.

I thought of mentioning this, then concluded that it shouldn't make a
difference. But it turns out that it matters if GRASS_GUI is set to
"wxpython".

If you "execute" a script by typing its name, it must be in $PATH. But
if you execute "sh" with the script filename as an argument, the shell
will just [f]open() it, and the normal rules apply (i.e. any path not
starting with a "/" is relative to the current directory).

And when g.parser invokes the script, it uses execl(), which doesn't
use the path.

AFAICT, the problem is when g.parser uses G_gui_wx(). Whereas
G_gui_tcltk() invokes gui.tcl and feeds it a description on its stdin,
G_gui_wx() invokes menuform.py with the command line, and G_gui_wx()
re-invokes the script with the --interface-description flag. The
script is exceuted using os.popen(), which uses /bin/sh, which uses
$PATH, hence the error.

So if you run the script with arguments (so that no dialog is
generated), or if GRASS_GUI is set to "tcltk", I think that it should
work regardless of whether the script is in $PATH.

Re: [GRASS-user] Opensource and pretty maps design anybody?

[kapo coulibaly]

Thank you all for your suggestions. I've used qgis quite a bit, it has a
nice GUI but it is not very good with pretty maps. I'll give the SVG format,
GMT and other graphic softwares a try. But how do you handle large numbers
of feature (contour labeling)? It can be pretty tedious if you are going to
cycle through various attributes attached to the same features. I think
there is a case to be made that there is a gap to be filled. Opensource GIS
software (Grass GIS, qGIS, Mapwindow, Saga...etc) could use some enhancement
in this department.

Malte,

You also may want to look at what Dylan Beaudette has done at the UC 
Davis Soil Resource Laboratory with 
http://casoilresource.lawr.ucdavis.edu/drupal/node/96


Go to:

"Cartographic Output via GMT", then select "An example on this website" 
which is: http://casoilresource.lawr.ucdavis.edu/drupal/node/102

[GRASS-user] datum not set in a mapset can I set it after it has been created

[stephen sefick]

I made a oopsie and did not set the datum in a mapset which is using
wgs84 by default, and my data is in nad83.  I have diligently kept all
of the source data in nad83 before import.  Can I change the datum?

[GRASS-user] 3D display warnings in MSWIndows

[Franz Schiller]

Greetings

I have installed a weekly snapshot
from grass-6.4.svn_src_snapshot_2010_07_24 in Windows and everytime I start
GRASS session (for instance with a raster display  (d.rast)) I get a bunch
of warnings:
3D view mode not available

Reason: No module named grass6_wxnviz

Note that the 3D view mode is currently not working under MS
Windows (hopefully this will be fixed soon). Please keep an
eye out for updated versions of GRASS.
Vector digitizer not available

Reason: No module named grass6_wxvdigit

Note that the vector digitizer is currently not working
under MS Windows (hopefully this will be fixed soon). Please
keep an eye out for updated versions of GRASS.

How can I turn this thing oFF?

Thanks

  Sure: psmap within GRASS. Or you can use any of the graphic applications
such as the GIMP, dia, Inkscape, etc.

  I've found that psmap produces outstanding output at a specified scale. It
takes a while to grok all the options and you need to build a text file to
produce what you want (no clicking, dragging, or other GUI stuff), but you
can put what you want exactly where you want it. I suppose you could also
use PSTricks with it but I've not looked at doing so.

[GRASS-user] Table is not created with vector map

[LeeDaniel]

Hello all,

I'm converting a raster to a vector with r.to.vect. The geometries are
converted successfully to vector shapes, but I noticed I was unable to work
further on the vectors' attribute table. When trying to add a field, I
received the following message:

Coor files of vector map  is larger than it should be
(94546466 bytes excess)

I then tried to open up the attribute table and was told that the attribute
table  could not be found. Interesting. A glance under the tab
"Manage Tables" showed no tables at all; I moved on to "Manage Layers" and
found only one layer, linked to my grass base and then
/Test/test/dbf/vector_map with the key cat. However, in my file manager I
don't see any such file, even when also viewing hidden files.

I tried connecting a new table with v.db.addtable, but got:
v.db.addtable map=vector_...@test table=test
Using user specified table name: test
ERROR: There is already a table linked to layer <1>

I've been able to duplicate this problem multiple times with the same
raster, but other vector maps I make from other rasters are created fine,
also with tables. Could the problem be connected to the high number of
features in the vector map? It's got almost a million. However, I've also
worked with vectors with more, which makes me doubt that hypothesis.

Thanks!
Daniel

[GRASS-user] r.sim.water buffer overflow

[Hanlie Pretorius]

Hi,

I'm using GRASS64 RC6 on Linux 10.04 (64-bit) and I'm trying to run
r.sim.water on a catchment about 5000 km2 in size.

I started with a very fine resolution in my region (00:00:00.18) and
got the following:
-

Since this resolution gives about 300 million cells in the region, I
progressively coarsened the resolution, but I get buffer overflows
even with just 2736 cells in the region (resolution = 00:01:00)
