按照这个例子,我创建了一个小 hello.pyd 库文件,其内容在这个问题的末尾。
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!
>>>
但是尝试使用 IronPython 的解释器会产生错误:
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?
你好模块.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);
}
安装程序.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
