在 IronPython 的解释器 (ipy.exe) 中导入 *.pyd 库
按照 this 示例,我创建了一个小 hello.pyd 库文件,其内容为 当我输入 python 解释器时,
我得到以下信息:
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 的解释器尝试此操作会产生错误:
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
>>>
如何使 ipy 解释器接受此 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
Following this example, I've created a little hello.pyd library file, the contents of which are at the end of this question.
When I enter python interpreter I get the following:
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!
>>>
But trying this with IronPython's interpreter yields an error:
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
>>>
How can I make ipy interpreter accept this C++ compiled library?
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])
Compiled as follows
python setup.py build -cmingw32

您可以尝试使用 Ironclad,但最近没有看到太多进展。
You can try using Ironclad, but it hasn't seen much work recently.
答案很可能是您的 .pyd 库不在 IronPython 获取它的正确路径中。由于您使用的是 Python 而不是 IronPython 的设置工具,因此它可能是在 PYTHONPATH 中构建和设置的,而不是 IronPython 需要的位置。
解决方案是 a.) 更改 IronPython 的路径或 b.) 在 IronPython 的路径中重建
The answer is most likely that your .pyd library isn't in the correct path for IronPython to pick it up. Since you used Python and not IronPython's setup tools, it probably got built and setup in the PYTHONPATH rather than where it needs to be for IronPython.
The solution is to a.) change your path for IronPython or b.) rebuild in IronPython's path
