Painless way to get C++ extensions in Python in Visual Studio 2005
I'm having some very serious compatibility issues with STLPort 5.1.0 and Boot.Python 1.46.1 in Visual Studio 2005, I was wondering if there was any other way to have Python calling C++ code.
Just in case someone can help: The following code compiels and runs without issue: char const* greet() { return "hello, world"; }
BOOST_PYTHON_MODULE(hello_ext)
{
using namespace boost::python;
def("greet", greet);
}
The linking errors start when I do something slightly more complex:
#include <iostream>
#include <boost/python.hpp>
using namespace boost::python;
struct World
{
std::string msg;
double mypi;
World(std::string msg): msg(msg) {} // added constructor
void set(std::string msg) { this->msg = msg; }
std::string greet() { return msg; }
double get() const { return mypi; }
void setter(double mypi) { this->mypi = mypi; }
};
BOOST_PYTHON_MODULE(hello_ext)
{
class_<World>("World", init<std::string>())
.def("greet", &World::greet)
.def("set", &World::set)
.def_readonly("msg", &World::msg)
.def_readwrite("mypi", &World::mypi)
.add_property("rovalue", &World::get)
.add_property("value", &World::get, &World::setter)
;
}
Unfortunately, I've been so frustrated that I've mangled my code to a point where I can reproduce the linkin开发者_开发技巧g errors because other compile errors are appearing. But the errors were linking errors for undefined symbols beginning with 'stlp' which I assume is referring to STLPort methods.
So at this point, I am simply looking for an alternative to Boost that's a bit easier to deal with in terms of compatibility.
Try using SWIG. I remember it being straight forward.
