sorry, small bug in my sample test. Here is a new attempt - sample script: """ #!/usr/bin/python from grass.lib.gis import * from grass.lib.vector import * map_obj = Map_info() map = pointer(map_obj) print os.environ['PYTHONPATH'] print sizeof(off_t) Vect_open_update(map, "a", "") p = Vect_new_line_struct() c = Vect_new_cats_struct() Vect_append_point(p, 1, 1, 0) Vect_cat_set(c, 1, 1) print p.contents.n_points Vect_write_line(map, GV_POINT, p, c) Vect_build(map) Vect_close(map) """ My system is Debian GNU/Linux unstable 32bit, the script works when GRASS compiled without LFS, with LFS it fails. /usr/local/src/grass_trunk/dist.i686-pc-linux-gnu/etc/python 8 /usr/local/src/grass_trunk/dist.i686-pc-linux-gnu/etc/python 8 D1/5: Vect__open_old(): name = a mapset = layer= (null) update = 1 D1/5: Vect_set_thresh(): thresh = 0.000000 D3/5: dig_init_plus() D3/5: dig_cidx_init() D1/5: G_find_vector2(): name=a mapset= D1/5: Map name: a D1/5: Map mapset: pg D1/5: open format file: 'pg/vector/a/frmt' D1/5: Vector format: 0 (native) D2/5: G__read_Cell_head D2/5: G__read_Cell_head_array ....
