I am using boost library version 1.54 with gcc --std=c++11.
I am trying a simple use of geometry::intersection as follows:
#include
#include
#include
#include
using namespace boost::geometry;
......
typedef model::d2::point_xy<double> point_xy;
model::polygon clipBounds;
// add points to clipBounds
model::polygon area;
// add points to area
model::polygon result;
if(boost::geometry::intersection(area, clipBounds, result))
{
std::cout << std::endl << "Boost intersection, size = " <<
num_points(result) << std::endl;
}
If I comment out the call to intersection, everything compiles. With it I
get:

typedef typename f_::type type;
Since my code is virtually identical to the sample code in the
documentation, I am very puzzled by this. What have I missed? How do I get
this to compile?
(I do find it odd that this error refers to boost/serialization rather than
boost/geometry, but I suppose that has to do with the order of inclusion).
