Boost error from XlC11. 01 using BOOST 1.53 in union

[devika.rs@…]

Hi All,

We are trying to compile sample boost code to demonstrate union on Aix64: Testcase: http://www.boost.org/doc/libs/1_55_0/libs/geometry/doc/html/geometry/reference/algorithms/union_.html

Following are the details of compiler Xlc Version:Version: 11.01.0000.0011 OS version:6100-06-05-1115 Boost version:1.53

It throws errors: "/usr/vacpp/include/vector.t", line 163.36: 1540-0716 (S) The template argument "std::vector<boost_1_53_0::geometry::model::ring<boost_1_53_0::geometry::model::d2::point_xy<double,boost_1_53_0::geometry::cs::cartesian>,1,1,std::vector<boost_1_53_0::geometry::model::ring<boost_1_53_0::geometry::model::d2::point_xy<double,boost_1_53_0::geometry::cs::cartesian>,1,1,std::vector<boost_1_53_0::geometry::model::ring<boost_1_53_0::geometry::mod..." does not match the template parameter "template class Container".

Is this a known bug ? Please help us in case a patch is available.

Hi,

I personally am not aware of this problem. I have no access to an AIX machine.

Is the code in test.cpp exactly the same as on the page? Or have you tried the example contained in BOOST_ROOT/libs/geometry/doc/src/examples/algorithms/union.cpp (​https://github.com/boostorg/geometry/blob/boost-1.53.0/doc/src/examples/algorithms/union.cpp) ?

Could you try to find what exactly fails to compile. Is it model::polygon, read_wkt or union_? Are you able to compile the bg::model::polygon properly? For example:

    typedef boost::geometry::model::d2::point_xy<double> point;
    typedef boost::geometry::model::polygon<point> polygon;

    polygon p;

If it was ok and you tried to add other things from the example, when does the code stop to compile?

Could you provide more info or contact the developers on the mailing list (​http://lists.boost.org/mailman/listinfo.cgi/geometry)?

Hi,

read_wkt is not causing the problem.

These four line:

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

polygon green, blue;

std::vector<polygon> output;

boost::geometry::union_(green, blue, output);

Please find the attachment union.txt for full error message.

Apparently the geometry::model::ring class itself does not compile:

"/remote/ports/aix/xlcpp11_1_aix53/usr/vacpp/include/vector.t", 
line 163.36: 1540-0716 (S) The template argument 
"std::vector<boost_1_53_0::geometry::model::ring
<boost_1_53_0::geometry::model::d2::point_xy
<double,boost_1_53_0::geometry::cs::cartesian>,1,1,
std::vector<boost_1_53_0::geometry::model::ring
<boost_1_53_0::geometry::model::d2::point_xy
<double,boost_1_53_0::geometry::cs::cartesian>,1,1,
std::vector<boost_1_53_0::geometry::model::ring
<boost_1_53_0::geometry::mod..." 

does not match the template parameter "template class Container".

What kind of STL is used by AIX? Is it compliant? Can you maybe use stlport?

I'm guessing that at this point we shouldn't change the definition of a model::ring<> and model::polygon<>. So we are unable to fix it on our side.

But those types (model::ring, model::polygon) are just the default ones implemented for the users convenience. Boost.Geometry allows to use any user-defined type as long as it's adapted to one of the Geometry concepts. See:

• http://www.boost.org/doc/libs/1_57_0/libs/geometry/doc/html/geometry/reference/concepts.html

and in particular:

• http://www.boost.org/doc/libs/1_57_0/libs/geometry/doc/html/geometry/reference/concepts/concept_ring.html
• http://www.boost.org/doc/libs/1_57_0/libs/geometry/doc/html/geometry/reference/concepts/concept_polygon.html

You could implement your own ring and polygon types, adapt them to Boost.Geometry concepts and use with the algorithms. Consider one of the methods below:

USE MACRO FOR ADAPTATION

You could use one of the REGISTER_XXX macros which generates the adaptation code automatically, see:

• http://www.boost.org/doc/libs/1_57_0/libs/geometry/doc/html/geometry/reference/adapted/register.html

and in particular:

• http://www.boost.org/doc/libs/1_57_0/libs/geometry/doc/html/geometry/reference/adapted/register/boost_geometry_register_ring.html
• http://www.boost.org/doc/libs/1_57_0/libs/geometry/doc/html/geometry/reference/adapted/register/boost_geometry_register_ring_templated.html

It could look as simple as this:

typedef boost::geometry::model::d2::point_xy<double> point_2d;
struct ring_2d : public std::vector<point_2d> {}
BOOST_GEOMETRY_REGISTER_RING(ring_2d)

ADAPT YOUR OWN TYPE MANUALLY

The most simple way of doing it would be to copy the contents of Boost.Geometry files defining the models, e.g. see:

• ​https://github.com/boostorg/geometry/blob/master/include/boost/geometry/geometries/ring.hpp
• ​https://github.com/boostorg/geometry/blob/master/include/boost/geometry/geometries/polygon.hpp

Then remove unneeded template parameters (e.g. Container for ring and PointList,RingList for polygon) and internally use e.g. std::vector<> everywhere instead. Then adapt this type properly, so remove the template parameters also from traits' specializations below, etc.
