If (inside a GRASS session), I access with v.db.connect -p map=GU0507
it looks ok :
Vector map <gu0...@simon9> is connected by:
layer <1> table <GU0507> in database
</home/rabotin/grassdata/Roujan/simon9/dbf/> through driver <dbf> with
key <cat>
Do you know how to launch a grass command (e.g. v.db.connect) inside a C
script
I try this line in my C progam
system(v.db.connect -p map=GU0507)
but I have an error message
sh: v.db.connect: not found

And I got a zero value return . So my driver isn't set ?
Is the problem from the following lines :
setenv("DBF_DRIVER","dbf",1);
setenv("DB_DATABASE","$GISDBASE/$LOCATION_NAME/$MAPSET/dbf",1);
These will be ignored. The default DBMI settings are taken from the
VAR file, not the environment. But you're use the settings from an
existing vector map.
I didn't write but I use grass 6.4 on ubuntu 9.10.
Do you know other commands to test or to set the dbf driver than
db_start_driver command ?
The code looks okay. Can you access the map's attribute table using
existing GRASS modules, e.g."v.db.connect -p ..."?
