unresolved external symbol geos::geom::GeometryFactory::createPolygon

[Kees]

error LNK2019: unresolved external symbol "public: class geos::geom::Polygon * thiscall geos::geom::GeometryFactory::createPolygon(class geos::geom::LinearRing *,class _STL::vector<class geos::geom::Geometry *,class _STL::allocator<class geos::geom::Geometry *> > *)const " (?createPolygon@GeometryFactory@geom@geos@@QBEPAVPolygon@23@PAVLinearRing@23@PAV?$vector@PAVGeometry@geom@geos@@V?$allocator@PAVGeometry@geom@geos@@@_STL@@@_STL@@@Z) referenced in function _main

Occured in example:

vector<​geos::geom::Geometry*> inner_holes; vector<​geos::geom::Geometry*> outer_holes;

geos::geom::DefaultCoordinateSequence* innerSequence=new geos::geom::DefaultCoordinateSequence();

innerSequence->add(geos::geom::Coordinate(1, 1));

innerSequence->add(geos::geom::Coordinate(2, 1));

innerSequence->add(geos::geom::Coordinate(2, 2)); innerSequence->add(geos::geom::Coordinate(1, 1)); geos::geom::LinearRing* innerRing = global_factory.createLinearRing(innerSequence);

geos::geom::Polygon* innerPolygon = global_factory.createPolygon(innerRing,&inner_holes);

The problem is with createPolygon because no unresolved externals will be created when this method is left out of the example.
