Я пытаюсь построить интерфейсы движка c ++ для python, используя boost / python. Импорт python завершается неудачно в среде анаконды. Я сократил c ++ до следующего (простой python. cpp), который все еще не работает:
#include <boost/python/module.hpp>
#include <boost/python/class.hpp>
namespace R3 {
class Coordinate {
public:
Coordinate() : x(0), y(0), z(0) {}
Coordinate(int _x, int _y, int _z) : x(_x), y(_y), z(_z) {}
double getX() const { return x;}
double getY() const { return y;}
double getZ() const { return z;}
private:
double x, y, z;
};
}
BOOST_PYTHON_MODULE(simplepython) {
// An established convention for using boost.python.
using namespace boost::python;
Py_Initialize();
class_<R3::Coordinate>("R3Coordinate", init<>())
.def(init<int, int, int>())
.def("getX", &R3::Coordinate::getX)
.def("getY", &R3::Coordinate::getY)
.def("getZ", &R3::Coordinate::getZ)
;
}
, пробуя это:
$> python - c 'import sys; печать (sys.executable); импорт простой python
