dear grass-friends,
i have downloaded the actual suse-rpm´s from the link on the official site (http://www.gdf-hannover.de/software).
the files are called:
geos-2.0.0-1.suse91.i586.rpm
grass-6.0.0-1.suse91.i586.rpm
...
i wanted to install the files with yast on my 9.2.suse-machine, but nothing happend.
i had to rename alle the files without *.suse91.* (grass-6.0.0-1.i586.rpm, etc.), then i could install them without problems.
--------------
i have a polygon-vector-layer in grass with a lot columns in the attribute table.
i've looked in the manual of v.db.update, but there is still a question:
i have three coloumns BID, GDNR, PROJNR, FNR (all number-coloumns)
is it possible to update the coloumn BID with an expression like GDNR + PROJNR + FNR (the sum of the mathematical addition) or FNR + (PROJNR * 100) + (GDNR * 10000).
i tried this above, but i always get an error-message.
thanks with greetings from tyrol
helli
os: suse linux 9.2
