Question

我正在尝试为python创建C ++扩展。我的C ++代码依赖于STLPort 5.1.0。我用stdlib = stlport编译了boost.python。这发生在我的编译器中，即Microsoft Visual Studio 2005。

但是当我尝试编译测试项目时，我不断收到以下链接错误。

stdafx.h包含：

// STL
#include <string>
#include <fstream>
#include <sstream>
#include <vector>
#include <iostream>
using namespace std;

// Boost
#include <boost/shared_ptr.hpp>
#include <boost/algorithm/string.hpp>
#define BOOST_PYTHON_STATIC_LIB

TestProject.cpp： #include“stdafx.h” #include“TestProject.h”

/**Python Link Begin**/
#include <boost/python.hpp>
#include <boost/random.hpp>
#include <boost/random/normal_distribution.hpp>

using namespace boost::python;

boost::mt19937 gen;
struct World
{
    std::string msg;
    double mypi;

    World(std::string msg): msg(msg) {
        gen.seed(std::time(0));
    } // 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; }

    double getgaussrand() {
        boost::normal_distribution<> nd(0.0, 1.0);
        boost::variate_generator<boost::mt19937&, boost::normal_distribution<> > var_nor(gen, nd);
        return var_nor();
    }

};

BOOST_PYTHON_MODULE(TestProject)
{
    class_<World>("World", init<std::string>())
        .def("greet", &World::greet)
        .def("set", &World::set)
        .def("getgaussrand", &World::getgaussrand)
        .def_readonly("msg",  &World::msg)
        .def_readwrite("mypi", &World::mypi)
        .add_property("rovalue", &World::get)
        .add_property("value", &World::get, &World::setter)
    ;
}

最重要的是，以下链接错误导致：错误2错误LNK2019：未解析的外部符号“类boost :: python :: api :: object __cdecl boost :: python :: objects :: function_object（struct boost :: python :: objects :: py_function const＆amp;，struct stlpd_std：：pair const＆amp;）“（？function_object @ objects @ python @ boost @@ YA？AVobject @ api @ 23 @ ABUpy_function @ 123 @ ABU？$ pair @ PBUkeyword @ detail @ python @ boost @@ PBU1234 @@ stlpd_std @@ @Z）函数中引用“类boost :: python :: api :: object __cdecl boost :: python :: detail :: make_function_aux，类stlpd_std :: allocator＆gt;（__ thiscall World :: *）（void），struct boost :: python :: default_call_policies，struct boost :: mpl :: vector2，class stlpd_std :: allocator＆gt;，struct World＆amp;＆gt ;, struct boost :: mpl :: int_＆lt; 0＆gt;＆gt;（class stlpd_std :: basic_string ，类stlpd_std :: allocator＆gt;（__ thiscall World :: *）（void），struct boost :: python :: default_call_policies const＆amp;，struct boost :: mpl :: vector2，class stlpd_std :: allocator＆gt ;,struct World ＆amp;＆gt; const＆amp;，struct stlpd_std :: pair const＆amp;，struct boost :: mpl :: int_ ＆lt; 0＆gt;）“（?? $ make_function_aux @ P8World @@ AE？AV？$ basic_string @ DV？$ char_traits @ D @ stlpd_std @@ V？$ allocator @ D @ 2 @@ stlpd_std @@ XZUdefault_call_policies @ python @ boost @@ U＆$ vector2 @ V'$ basic_string的@ DV？$ char_traits @ d @ @@ stlpd_std V'$分配器@ d @ @@ 2 @@ stlpd_std @@@ AAUWorld MPL @ 6 @ U＆$ INT _ @ $ 0A @@ 86 @@细节@蟒蛇@升压@@ YA？AVobject @ API @ 12 @ P8World @@ AE？AV？$ @的basic_string DV？$ @ char_traits @ d @@ stlpd_std V'$ @分配器@ d @@ 2 stlpd_std @@ @ XZABUdefault_call_policies 12 @ ABU？$ vector2 @ V'$ basic_string的@ DV？$ char_traits @ d @ @@ stlpd_std V'$分配器@ d @ @@ 2 @@ stlpd_std @@@ AAUWorld MPL @ 2 @ ABU？ $ pair @ PBUkeyword @ detail @ python @ boost @@ PBU1234 @@ 7 @ U？$ int _ @ $ 0A @@ mpl @ 2 @@ Z）TestProject.obj

如果我没记错的话，Boost Python库要求您提前构建它，以便使用它的项目可以链接它。你有没有这样做过？

将错误Boost.Python与stlport链接为stdlib
