在IronPython的解释器(ipy.exe)中导入* .pyd库

this示例之后,我创建了一个小的hello.pyd库文件,其内容位于此问题的最后。

当我输入python解释器时,我得到以下内容:

D:\test\build\lib.win32-2.6>C:\Python26\python.exe
Python 2.6.6 (r266:84297, Aug 24 2010, 18:46:32) [MSC v.1500 32 bit (Intel)] on win32
Type "help", "copyright", "credits" or "license" for more information.
>>> import hello
>>> hello.say_hello("Greg")
Hello Greg!
>>>

但是使用IronPython的解释器尝试这个会产生错误:

D:\test\build\lib.win32-2.6>"C:\Program Files (x86)\IronPython 2.7\ipy.exe"
IronPython 2.7 Alpha 1 (2.7.0.1) on .NET 4.0.30319.1
Type "help", "copyright", "credits" or "license" for more information.
>>> import hello
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
ImportError: No module named hello
>>>

如何让ipy解释器接受这个C ++编译库?


hellomodule.cpp

#include "C:\Python26\include\Python.h"

static PyObject* say_hello(PyObject* self, PyObject* args)
{
    const char* name;

    if (!PyArg_ParseTuple(args, "s", &name))
        return NULL;

    printf("Hello %s!\n", name);

    Py_RETURN_NONE;
}

static PyMethodDef HelloMethods[] =
{
     {"say_hello", say_hello, METH_VARARGS, "Greet somebody."},
     {NULL, NULL, 0, NULL}
};

PyMODINIT_FUNC

inithello(void)
{
     (void) Py_InitModule("hello", HelloMethods);
}

setup.py

from distutils.core import setup, Extension

module1 = Extension('hello', sources = ['hellomodule.cpp'])

setup (name = 'PackageName',
        version = '1.0',
        description = 'This is a demo package',
        ext_modules = [module1])

编译如下

python setup.py build -cmingw32

您可以尝试使用Ironclad,但最近没有看到太多工作。

答案很可能是你的.pyd库没有正确的路径供IronPython选择它。由于您使用的是Python而不是IronPython的设置工具,它可能是在PYTHONPATH中构建和设置的,而不是IronPython所需的位置。

解决方案是a。)改变你的IronPython路径或b。)在IronPython的路径中重建
