This will be a "dependency hell" problem between GDAL and GRASS binaries,
probably a stale GRASS GDAL plugin somewhere. It has been seen on Debian
based distributions before, for example:

http://lists.osgeo.org/pipermail/grass-stats/2009-July/001105.html

Most likely you have multiple GDAL and/or GDAL binaries that do not like
each other, and because of the possible reverse dependence in the GDAL
GRASS plugin, they get in each others' way. The grass-stats list may be a
good place to ask too.

I suspect that instead the LD link to the GRASS libraries is missing. I have
a file (create as root):

# something like this (adapt path):
cat /etc/ld.so.conf.d/grass.conf
/usr/local/grass640/dist.x86_64-unknown-linux-gnu/lib

The program "ldconfig" needs to be run afterwards.

Hope this helps
Markus

I've upgraded to qgis 1.2.0-2~jaunty1build1
and ligdal1-1.6.0-grass 1.6.0-3~jaunty1
and everything seems to work fine regarding the qgis grass link.

Regarding R - grass:
If I :
1. start qgis
2. start qgis grass plugin
3. open mapset
4.open maptools
5.open grass shell
6. start R
7. require(spgrass6)
8.gmeta6() works fine

but if I
5. open grass shell
5a. open en xterm &  (as I've always done, so that I keep an open grass
console)
6 start R in the new xterm
7. require(spgrass6) works fine (and notifies the mapset)
8. gmeta6() does not work:
 > gmeta6()
g.region: error while loading shared libraries: libgrass_vect.so: cannot
open shared object file: No such file or directory
Error in if (file.exists(file) == FALSE) if (!missing(asText) && asText
==  :
  argument is of length zero
Error in parseGRASS(cmd) : g.region not parsed

It might be a different behavior of ubuntu jaunty at opening new xterm
consoles?

Markus,

gemeta6() works fine from any xterm console created
from the grass console after changing
/usr/lib/grass/lib
to
/usr/lib/grass64/lib

in grass.conf
as you suggested.

I don't remember having made grass.conf though, is there any way
for the installation to actually take place of this change of
the grass directory name?

Thanks!

Agus

Excellent!

Indeed it is the job of the package manager which installs the
GRASS-GDAL plugin (or whereever this should happen). If needed,
please file a bug there in case it is missing on Ubuntu.

Glad to know it solved for now,
Markus
