python - 尝试使用 cython 和 mingw 编译 hello world 时出错

Question

我已经花了 2 天时间尝试了我在这个网站上看到的所有其他内容。我试图让 cython 在 python 中编译基本的 helloworld 脚本，但有错误。尽管列出的路径是正确的并且我已经验证文件在那里(例如 c:/Python27/include/pyconfig.h)我已经包含了使用的文件，但 Gcc 似乎无法看到 python 头文件我的设置。

Hello World .pyx

print 'Hello World'

设置.py

from distutils.core import setup
from Cython.Build import cythonize

setup(
    ext_modules = cythonize("helloWorld.pyx")
)

命令行

python setup.py build_ext --inplace --compiler=mingw32

错误

Answer 1

正如 IanH 评论的那样，GCC 似乎无法找到 Python header 中包含的标准 C header ，而不是 Cython 的问题。你能编译一个简单的 C 程序吗，如下所示:

#include <stdio.h>
int main(void)
{
  printf("Hello World\n");
  return 0;
}

编译:

$ gcc hello.c -o hello.exe
