如何建立与Python中的MinGW-W64我的C扩展？(How can I build my C

所以，我有一些Python的C扩展我以前建的和在Win7上运行32位Python的使用。我现在已经切换不过来64位Python和我有建立C扩展使用MinGW-W64的问题。

我所做的更改的distutils按照这个帖子，但我得到一些奇怪的错误提示什么是错的：

我用Google搜索周围相当多的查找信息，但它是不容易找到一个明确的答案。可能有人阐明这一些轻？我应该做哪些进一步的变化能够成功地打造C扩展为64位的Python在Win7？

编辑：

在cgohlke的评论了一些有用的指针后下面我设法生成libpython27.a 。在下面的意见后，但是这个帖子（第二到最后一个）我仍然有一个的__imp_Py_InitModule4_64错误。一些严重的谷歌福后，我设法绊倒这篇文章告诉我重命名Py_InitModule4线Py_InitModule4_64 。之后，一切都顺顺当当的工作。

这为我工作与Python 3.3：

创建DLL静态蟒蛇LIB

蟒DLL通常在C：/窗/ System32下; 在MSYS壳：

 gendef.exe python33.dll dlltool.exe --dllname python33.dll --def python33.def --output-lib libpython33.a mv libpython33.a C:/Python33/libs

使用痛饮生成的包装
例如， swig -c++ -python myExtension.i

包装必须用MS_WIN64进行编译，或者当您导入在Python类电脑会崩溃

 g++ -c myExtension.cpp -I/other/includes g++ -DMS_WIN64 -c myExtension_wrap.cxx -IC:/Python33/include

共享库

 g++ -shared -o _myExtension.pyd myExtension.o myExtension_wrap.o -lPython33 -lOtherSharedLibs -LC:/Python33/libs -LC:/path/to/other/shared/libs

确保所有共享库（GDAL，OtherSharedLibs）在路径（Windows不使用LD_LIBRARY_PATH或PYTHONPATH）
在Python，只是：进口myExtension

瞧！

Answer 2:

下面是一个VC的示例代码++生成工具https://github.com/starnight/python-c-extension/tree/master/00-HelloWorld

你可以试试：

python setup.py -c mingw32

然而，这不是为我工作。

我的解决办法是：

安装64位蟒蛇蟒蛇3.6
安装mingw64
添加mingw64 / bin添加到PATH

从编译C文件的dll通过

 gcc -c libmypy.c -IC:\Users\{user_name}\Anaconda3\pkgs\python-3.6.4-h6538335_1\include gcc -shared -o libmypy.dll libmypy.o -LC:\Users\{user_name}\Anaconda3\pkgs\python-3.6.4-h6538335_1\libs -lPython36

在脚本的.py加载DLL文件

 from ctypes import * m = cdll.LoadLibrary(r"C:\{path_to_dll}\libmypy.dll") print(m.hello())
