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.

Build environment: Windows XP, Visual Studio 7.1, STLPort 4.6.2.

I've tested and GEOS 3.0.0 successfulyl builds with both compilers

• Microsoft (R) 32-bit C/C++ Optimizing Compiler Version 13.10.6030 for 80x86
• Microsoft (R) 32-bit C/C++ Optimizing Compiler Version 15.00.30729.01 for 80x86

However, GEOS 3.0.0 package includes broken makefile.vc (need to remove .obj entries for non-existing files) and dirlist.mk is missing.

Closing as fixed.

I'm having the exact same problem under MacOS X 10.6, with both GCC 4.0 and 4.2, both with the framework and installing from source. I tried with GEOS 3.1.1 and 3.2.0.

It affects: geos::geom::createPolygon(geos::geom::LinearRing? *, std::vector<geos::geom::Geometry *> *) const geos::geom::createPolygon(geos::geom::LinearRing? &, std::vector<geos::geom::Geometry *> &) const

The createPolygon() function works well, and this is only for the C++ interface.

Is this still an issue ? Tried 3.2.2 as well ?

[strk]

lack of response from people willing to build on those architectures is a won't fix for me
