编译错误而在Visual Studio 2017 Pybind11建设CPP为Python

问题描述 投票:0回答:2

这个查询就在微软文档中的教程标题Create a C++ extension for Python

我已经做了所有的指令按照教程。我使用的是Windows 10 64位和安装了多个版本的Python,我通常所说的py -x.x-xx sample.py。在此我已经安装了Visual Studio 2017 Python开发选项,包括的Python 3.6的32位和64位。

有两种方法在教程中所示:(1)CPython extensions和(2)Pybind11。我越来越多的错误与他们两个。不过,我决定追求Pybind11方式,因此上市与之相关的错误,因为它是清洁,需要对原来的C ++代码很少变化。

这是一块module.cpp文件:

#include <pybind11/pybind11.h>
#include <Windows.h>
#include <cmath>

const double e = 2.7182818284590452353602874713527;

double sinh_impl(double x) {
    return (1 - pow(e, (-2 * x))) / (2 * pow(e, -x));
}

double cosh_impl(double x) {
    return (1 + pow(e, (-2 * x))) / (2 * pow(e, -x));
}

double tanh_impl(double x) {
    return sinh_impl(x) / cosh_impl(x);
}

namespace py = pybind11;

PYBIND11_MODULE(superfastcode2, m) {
    m.def("fast_tanh2", &tanh_impl, R"pbdoc(
        Compute a hyperbolic tangent of a single argument expressed in radians.
    )pbdoc");

#ifdef VERSION_INFO
    m.attr("__version__") = VERSION_INFO;
#else
    m.attr("__version__") = "dev";
#endif
}

当我尝试建立按照本教程中的说明,下面是在日志中产生的错误:

我有完全相同的问题。由于连打后,我下载了GitHub上的教程相关的资料库:https://github.com/Microsoft/python-sample-vs-cpp-extension并通过项目配置去行由行。 (顺便提一下,其配置使用环境变量PYTHONPATH代替PYTHONHOME作为定向在教程)。

什么固定的问题对我来说是改变预处理器定义到:_WINDLL;%(PreprocessorDefinitions)相匹配的资源库版本。罪魁祸首似乎由教程劝Py_LIMITED_API定义:当我添加到列表中,再次出现问题。

正如我可以看到你想要编译例如32位的Python,它不能编译Python安装中的pybind11。

默认情况下,我有我的VS2017安装单独的64位的Python。所以,我对这样的64位配置的例子。

在superfastcode2请访问:

C / C ++ /一般/附加包含目录 - 添加$(PythonHome)Include$(ProjectDir)pybind11-master,最新的一个必须指向哪里pybind11安装(下载从GitHub的一个ZIP文件的位置,并将其解压到pybind11主目录,我把它里面的superfastcode2文件夹)。连接器/常规 - 添加$(PythonHome)libs

在superfastcode请访问:

C / C ++ /一般/附加包含目录 - 添加

C:\Program Files (x86)\Microsoft Visual Studio\Shared\Python36_64\include

连接器/常规 - 添加

C:\Program Files (x86)\Microsoft Visual Studio\Shared\Python36_64\libs

收藏此解决方法Python.h在module.cpp:

//Workaround for - LNK1104: cannot open file 'python36_d.lib'

#define HAVE_RND  //This makes always use the Release version of Python, even in Debug mode

#ifdef _DEBUG
#define RESTORE_DEBUG
#undef _DEBUG
#endif

#include <Python.h>

#ifdef RESTORE_DEBUG
#define _DEBUG
#undef RESTORE_DEBUG
#endif

修复路径:

#include <include/pybind11/pybind11.h>

应工作,然后。 ;)
