Veering slightly off topic but still related to Geometry development, I've hit some hurdles with the rtree index. I could create an index of points easily but then couldn't query for the nearest neighbour of a segment. (I assume this is simply not supported at present; is it forthcoming?) So I created a ring or polygon from the segment and tried to query for the points that it covers/intersects, which is a feature listed in the documentation, but I've hit this compilation error:

Which version of Boost are you using?

1.55.

Ahh, I had an almost identical test program except for one line. I had:

typedef boost::geometry::model::d2::point_xy<double> Point;

Is that type meant to have different behaviour to the general point model?

No, it should behave the same, and in that sense you have stumbled upon a bug. I reproduced the error, and I know how to fix it. I expect to create a PR for that within the day. I still have not figured out yet why there is a need for a fix, so please bare with me until I can give you a more complete status report. In any case it will be fixed in develop and you will be able to use either one of the point models in discussion. Best, - m.

Thanks for your help, cheers.

Jeremy
