108	build spatialite with librttopo support	Jeff McKenna	Jeff McKenna	" - main page: https://strk.kbt.io/projects/rttopo/

- IRC discussion

{{{
        GlennS	Hi, I'm wondering if anyone knows of a command line tool to fix invalid geometries? Something like PostGIS's ST_MakeValid, except without having to install PostGIS.
	GlennS	I know that Spatialite can also use this via librttopo, but I'm having trouble getting that working so thought I'd see if there was an easier way before I bang my head against it any further
	EvenR	GlennS: ogr2ogr out.shp in.shp -sql ""select ST_MakeValid(geometry), * FROM in"" -dialect SQLite
	GlennS	EvenR: I don't thing the spatialite which ships with ogr2ogr (or is it just using my system's library?) comes with ST_MakeValid by default? I get undefined function ST_MakeValid.
	EvenR	spatialite must be built against liblwgeom : https://www.gaia-gis.it/gaia-sins/spatialite-sql-4.3.0.html
	sigq	Title: SpatiaLite SQL functions reference list (at www.gaia-gis.it)
	GlennS	yeah, as I mentioned, I'm failing to do that
	GlennS	actually that information is out of date anyway
	GlennS	they've switched from liblwgeom to librttopo
