[GRASS-user] problems with GRASS 6.4

Hello list;

I have just installed the new Grass version but I haven’t been able to work with it!
If I try to launch the GRASS 6.4 ORC6 with the new wxpython GUI; I get an error message saying that python.exe has detected a problem and has to close. Further, I get this:

ERROR: G_getenv(): Variable LOCATION_NAME not set
Traceback (most recent call last):

If I try to use the very nice GRASS 6.4 ORC6 with MSYS interface; the computer gets blocked if I try to run a command.

Any idea of what the problem could be?

Thank you in advance

Miguel,
I had the same problem with osgeo4w.
Then I installed the RC6 with the installer (http://grass.osgeo.org/grass64/binary/mswindows/native/), after that both distributions worked very well.

I have no idea what it is, but it worked.

BTW, RC6 is very stable.

Hi,

I've installed spgrass6, which apparently went fine (on my mac).

All the examples I found run R commands from the GRASS console (hence not being necessary to specify the GRASS LOCATION, etc.

Isn't it possible to specify a GRASS LOCATION from within the R interface?

In R, I loaded spgrass6, then tried:

> initGRASS("/Applications/grass-6.4.app")

and I get:

/bin/sh: g.gisenv: command not found
Error in if (file.exists(file) == FALSE) if (!missing(asText) && asText == :
   argument is of length zero
Error in parseGRASS(cmd) : g.region not parsed
sh: g.region: command not found
>

----
If I want to start GRASS and open a specific mapset, would this work?

initGRASS("/Applications/grass-6.4.app", GISdbase="/Users/antonio/Documents/grass", location="pt_etrs89", mapset="interior")

(well, it doesn't, I'm just not sure why...)

Thank you
António

António,

You must run this from the GRASS term window; first start R at the GRASS shell prompt, by typing R; then load spgrass6: library(spgrass6) — the supporting libraries (sp, rgdal, etc.) must be installed in R first.

Regards,
Tom
