[GRASS-dev] strange problem using v.out.ogr

GRASS GRASS developer
1

Using a very recently compiled GRASS 7.9

I imported a gpkg vector area. This went fine AFAICT. It imported into the correct location. (ETRS89 Zone 30)

I want to export it to shapefile format.

When I try to export it to any format, I get the following error:

ERROR 10: Pointer ‘hSRS’ is NULL in ‘OSRImportFromWkt’.
ERROR: Unable to create OGR spatial reference

I’ve checked the projection info and it seems fine and does not raise any error or warning. I tried exporting a map from the NC demo data and it exported fine.

Any idea what is wrong?

Michael,

I get the same error when trying to export a vector map to shapefile using v.out.ogr. I daily build the main branch myself for OSGeo4W v1 (GDAL 3.1.4) on Windows [1]. It used to work fine before (cannot remember exactly when). My daily cross-compiled version using GDAL 2.2.4 still works fine [2]. It could be a GDAL 3 issue or a GRASS-GDAL 3 compatibility issue? Maybe, it’s worth trying our official Windows release…
