[geos-devel] Doubts

[vishal tiwari]

Hey,
I am facing some very silly problems when i try to compile
QuadEdgeSubdivision.cpp.
I have declared my getVoronoiCellPolygons as :
void
QuadEdgeSubdivision::getVoronoiCellPolygons(std::vector<geom::Geometry *>
&cells ,const geom::GeometryFactory& geomFact)
{
.....
.....
}

And I have definition it in QuadEdgeSubdiviion.h as:

void getVoronoiCellPolygons( std::vector<geom::Geometry *> &cells , const
geom::GeomtryFactory &geomFact);

And i am getting the following compilation error:
In file included from QuadEdgeSubdivision.cpp:18:
../../../include/geos/triangulate/quadedge/QuadEdgeSubdivision.h:425:
error: expected unqualified-id before ‘&’ token
../../../include/geos/triangulate/quadedge/QuadEdgeSubdivision.h:425:
error: expected ‘)’ before ‘&’ token
../../../include/geos/triangulate/quadedge/QuadEdgeSubdivision.h:425:
error: expected ‘;’ before ‘&’ token

Similar error is shown getVoronoiCellPolygon method:
getVoronoiCellPolygon.cpp:

geos::geom::Polygon*
QuadEdgeSubdivision::getVoronoiCellPolygon(QuadEdge* qe ,const
geom::GeomtryFactory& geomFact)
{
...........
...........
...........
}

getVoronoiCellPolygon.h

geos::geom::Polygon* getVoronoiCellPolygon(QuadEdge* qe ,const
geom::GeomtryFactory& geomFact);

../../../include/geos/triangulate/quadedge/QuadEdgeSubdivision.h:442:
error: expected unqualified-id before ‘&’ token
../../../include/geos/triangulate/quadedge/QuadEdgeSubdivision.h:442:
error: expected ‘)’ before ‘&’ token
../../../include/geos/triangulate/quadedge/QuadEdgeSubdivision.h:442:
error: expected ‘;’ before ‘&’ token

I have quantified it using the "::" operator and specified to which class
the methods belong to. Please help me out with this.
