Hi all.
I'm consistently getting a segfault from:
ogr2ogr OUTPUTLAYER.shp strade.shp strade -dialect sqlite -sql "SELECT
ST_Line_Interpolate_Point( geometry , 0.5 ),* FROM 'strade' "
Anything I can do for debugging?
Running under gdb and displaying the stack trace.
ogr2ogr OUTPUTLAYER.shp strade.shp -dialect sqlite -sql "SELECT
ST_Line_Interpolate_Point( geometry , 0.5 ),* FROM 'strade'"
ERROR 1: In ExecuteSQL(): sqlite3_prepare(SELECT
ST_Line_Interpolate_Point( geometry , 0.5 ),* FROM 'strade'):
no such function: ST_Line_Interpolate_Point
I have both SQLite and SpatiaLite support on. What's going on?
Not using a recent enough SpatiaLite I guess
I've now got the latest SpatiaLite version but ogr2ogr is still complaining.
However, I got also the SpatiaLite CLI and it has no problems:
spatialite> .loadshp strade strade utf8
========
Loading shapefile at 'strade' into SQLite table 'strade'
BEGIN;
CREATE TABLE "strade" (
"PK_UID" INTEGER PRIMARY KEY AUTOINCREMENT,
"id" INTEGER);
SELECT AddGeometryColumn('strade', 'Geometry', -1, 'LINESTRING', 'XY');
COMMIT;
Inserted 1 rows into 'strade' from SHAPEFILE
========
spatialite> SELECT astext(ST_Line_Interpolate_Point( geometry , 0.5 )),*
FROM 'strade';
POINT(-0.352046 0.4463)|1|0|
Hm.
Ari
