right, just facing to the strange problem, any idea? Sample script """ from grass.lib.vector import * map_obj = Map_info() map = pointer(map_obj) Vect_open_update(map, "a", "") print Vect_level(map) p = line_pnts() Vect_append_point(byref(p), 1, 1, 0) Vect_write_line(map, GV_POINT, byref(p), None) Vect_build(map) Vect_close(map) """ $ g.gisenv set=DEBUG=1 D1/3: Vect__open_old(): name = a mapset = layer= (null) update = 1 D1/3: Vect_open_old(): vector opened on level 1 D1/3: Vect_read_dblinks(): map = a, mapset = landa D3/3: Searching for FID column in OGR DB D1/3: dbln file: /home/martin/grassdata/nc_spm_08/landa/vector/a/dbln D1/3: Dblinks read D1/3: Vect_Rewind(): name = a 1 D3/3: Vect_write_line(): name = (null), format = 170241076, level = 0 ERROR: Unable to write feature, vector map is not opened The map is opened correctly, Vect_level() works. Anyway Vect_write_line() fails, seems to be that Map_info is corrupted. No clue at this moment.
