Re: [Boost-users] [boost::polygon::operators] Boolean operations compiler error

You could try: boost::polygon::assign(p3, p1&p2); Or, if you're using namespace boost::polygon::operators, you could write: p3 = p1; p3 &= p2; 2011/10/17 Dimitris Dakopoulos

Hello all, I'm using a custom polygon set (PolygonCollection) according to the guidelines here: http://www.boost.org/doc/libs/1_47_0/libs/polygon/doc/gtl_custom_polygon_set... There is one case that I don't get any compiler error:

PolygonCollection p1, p2; p1 & p2;

There is this case that I do have an error:

PolygonCollection p1, p2; PolygonCollection p3 = p1 & p2;

The error is: error: conversion from 'boost::polygon::polygon_set_view' to non-scalar type 'PolygonCollection' requested

There is also this case that I have a compiler error:

PolygonCollection p1,p2,p3; p3 = p1 & p2;

The error is:error: no match for 'operator=' in 'p3 = boost::polygon::operators::operator&(const geometry_type_1&, const geometry_type_2&) [with geometry_type_1 = PolygonCollection, geometry_type_2 = PolygonCollection](((const PolygonCollection&)((const PolygonCollection*)(& p1))))' /xxx/Polygon.hpp:182: note: candidates are: PolygonCollection& PolygonCollection::operator=(const PolygonCollection&)

(You can notice that I have overloaded the operator= for my custom polygon set but I got the same error without the suggestion before my implementation)

Any ideas are welcomed!

Dimitris
