Question

我在64位python 2.7的64位窗口上工作，我正在尝试为python编译我的第一个c ++扩展。起初我尝试使用mingw但遇到了很多链接器错误，所以现在我使用c ++ for python 2.7和windows7 SDK。

它应该是一个存储c ++ map，map<tuple<int,int,int>,pen>和map<int,pen>两倍的对象，其中pen是一个c ++结构。

类的标题（Tactic.h）：

#include <iostream>
#include <string>
#include <string.h>
#include <sstream>
#include <map>
#ifndef TACTIC
#define TACTIC
#include <tuple>
#include <vector>
using namespace std;
struct pen
{
public:
    pen():p0(-15),p1(-15),p2(-15),p3(-15),
        p4(-15),p5(-15),p6(-15),
        p7(-15),p8(-15),p9(0){}
    signed int p0:11;
    signed int p1:11;
    signed int p2:11;
    signed int p3:11;
    signed int p4:11;
    signed int p5:11;
    signed int p6:11;
    signed int p7:11;
    signed int p8:11;
    signed int p9:4;
};
class Tactic
{
    public:
        Tactic();
        Tactic(vector<vector<int>> &map1, vector<vector<int>> &map2);
        ~Tactic();
        void adjust_map1(int k0, int k1,int k2,const char *act, int modifier);
        void adjust_map2(int key,const char *act, int modifier);
        vector<int> get_map1(int key);
        vector<int> get_map2(int k0, int k1,int k2);
        vector< vector < vector<int> > > get_list();
        void load_dict(vector< vector < vector<int> > > dict_list);
    private:
        map<int,pen> *map1;
        map<tuple<int,int,int>,pen> *map2;
};
#endif

setup.py：

导入os

from setuptools import setup
from setuptools import Extension
from Cython.Build import cythonize

ext_modules=[
    Extension("tactic",
        extra_compile_args=["/EHsc"],
        sources = ["tactic.pyx","Tact_source.cpp"],
        language = "c++",)]
setup(
    name="tactic",
    ext_modules = cythonize(ext_modules),)

命令python setup.py build_ext --inplace -compiler=msvc失败并出现以下错误：

D:\...>python setup.py build_ext --inplace -compiler=msvc

error: command '"C:\Users\....\AppData\Local\Programs\Common\Microsoft\Visual C++ for Python\9.0\VC\Bin\amd64\cl.exe"' failed with exit status 2

所以，似乎虽然我导入了元组，但编译器找不到元组的声明。有谁知道问题是什么？这可能不是编译器而是链接器错误吗？提前感谢您的帮助。

过时的Visual Studio 2008 C ++编译器在tuple命名空间中没有std但在std::tr1中没有，因此将std::tuple的实例替换为std::tr1::tuple应该有效

msdn docs

中也记录了这一点
