Python：在AcANDA（Windows）中构建C++模块作为共享对象而不是扩展 假设您有一个C++函数，您想在Python中使用Python。CPP extern "C" int fun(int i) { return i*2; }

然后可以使用下面的setup.py

from distutils.core import setup, Extension

module1 = Extension('fun', sources = ['src/fun.cpp'],include_dirs = ['src/'])

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

然后在这个有趣的软件包中，您可以有以下内容

import ctypes   
fun = ctypes.cdll.LoadLibrary(__path__[0]+"/../fun.so").fun
fun.restype = ctypes.c_int
fun.argtype = ctypes.c_int

所以你可以像这样使用它

>>import fun
>>fun.fun(2)
>>4

:

这在Linux中工作得非常好，但是当我在Windows上使用Anaconda尝试这一点时，首先链接器要求我提供一个initfun符号，这意味着它正在尝试构建一个python扩展，而不仅仅是构建一个共享对象。有人知道如何更改setup.py或Anaconda设置来构建共享对象并将其与ctypes.cdll.LoadLibrary函数一起使用吗

提前感谢。

我终于使用了这个解决方案。它并没有尽可能的干净，因为它试图以一种不安全的方式找到蟒蛇的路径

from distutils.core import setup, Extension

from sys import platform as _platform
if _platform == "linux" or _platform == "linux2":
    module1 = Extension('fun/fun', sources = ['src/fun.cpp','src/cochlea.cpp'],include_dirs = ['src/'], extra_compile_args=['-Ofast','-flto','-march=native','-funroll-loops'] )
    setup (name = 'fun',
        version = '1.0',
        description = 'This is a demo package',
        ext_modules = [module1],
        packages = ['fun'])

elif _platform == "darwin":
    module1 = Extension('fun/fun', sources = ['src/fun.cpp','src/cochlea.cpp'],include_dirs = ['src/'], extra_compile_args=['-Ofast','-flto','-march=native','-funroll-loops'] )
    setup (name = 'fun',
        version = '1.0',
        description = 'This is a demo package',
        ext_modules = [module1],
        packages = ['fun'])

elif _platform == "win32":


    import sys
    for a in sys.path:
        f = a.find('Anaconda')
        if f!=-1:
            path = a[:f+9]

    import os

    os.system("gcc.bat -mdll -O -Wall -Isrc/ -I"+path+"include -I"+path+"PC -c src/fun.cpp -o fun.o -Ofast -flto -march=native -funroll-loops") 
    os.system("g++.bat -shared -s fun.o -o fun.dll") 

    setup (name = 'fun',
            version = '1.0',
            description = 'This is a demo package',
            package_data={'fun': ['fun.dll']},
            packages = ['fun'])
