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，但是有错误。 Gcc 似乎无法看到 python 头文件，尽管列出的路径是正确的并且我已经验证了文件在那里（例如 c:/Python27/include/pyconfig.h） 我已经包含了使用的文件我的设置。

helloWorld.pyx

print 'Hello World'

setup.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

编译 helloworld.pyx 因为它发生了变化。 Cythonizing helloworld.pyx 运行 build_ext 构建“helloworld”扩展 C:\MinGW\bin\gcc.exe -mno-cygwin -mdll -O -Wall -IC:\Python27\include -IC:\Pytho n27\PC -c helloworld.c -o build\temp.win32-2.7\Release\helloworld.o 在包含的文件中 helloworld.c:8: C:/Python27/include/pyconfig.h:68:16: io.h: 没有 文件或目录 C:/Python27/include/pyconfig.h:296:20: stdio.h: 否 这样的文件或目录在包含的文件中 C:/MinGW/bin/../lib/gcc/mingw32/3.4.5/include/limits.h:122 ，来自 C:/MinGW/bin/../lib/gcc/mingw32/3.4.5/include/syslimits.h: 7，来自 C:/MinGW/bin/../lib/gcc/mingw32/3.4.5/include/limits.h:11，来自 C:/Python27/include/Python.h:19，来自 helloworld.c:16： /mingw/lib/gcc/mingw32/3.4.5/include/limits.h:122:61：limits.h：否 这样的文件或目录在 helloworld.c:16 包含的文件中： C:/Python27/include/Python.h:35:5: #error "Python.h 要求 stdio.h 定义 NULL。” C:/Python27/include/Python.h:38:20: string.h: 否 这样的文件或目录 C:/Python27/include/Python.h:40:19: errno.h: 否 这样的文件或目录 C:/Python27/include/Python.h:42:20: stdlib.h: 没有这样的文件或目录 C:/Python27/include/Python.h:56:20: assert.h：在包含的文件中没有这样的文件或目录 C:/Python27/include/Python.h:58，来自 helloworld.c:16： C:/Python27/include/pyport.h:325:76: math.h: 没有这样的文件或目录 C:/Python27/include/pyport.h:338:18:time.h: 没有这样的文件或目录 C:/Python27/include/pyport.h:390:22: sys/stat.h: 没有这样的文件或 目录在 C:/Python27/include/Python.h:80 包含的文件中，来自 helloworld.c:16: C:/Python27/include/object.h:307: 错误：语法错误 在“文件”C:/Python27/include/object.h:459 之前：错误：语法错误 在“文件”之前从 C:/Python27/include/Python.h:85 包含的文件中， 来自 helloworld.c:16: C:/Python27/include/unicodeobject.h:57:19: ctype.h：没有这样的文件或目录 C:/Python27/include/unicodeobject.h:120:21: wchar.h: 没有这样的文件或 目录在 C:/Python27/include/Python.h:108 包含的文件中，来自 helloworld.c:16: C:/Python27/include/fileobject.h:12: 错误：语法 “文件” C:/Python27/include/fileobject.h:12 之前的错误：警告：否 结构或联合末尾的分号 C:/Python27/include/fileobject.h:15: 错误: '' 之前的语法错误 令牌 C:/Python27/include/fileobject.h:33: 错误：之前的语法错误 '}' 标记 C:/Python27/include/fileobject.h:33：警告：类型默认值 到int' in declaration ofPyFileObject' C:/Python27/include/fileobject.h:33：警告：数据定义没有 类型或存储类 C:/Python27/include/fileobject.h:44: 错误： '' 标记 C:/Python27/include/fileobject.h:45 之前的语法错误： 错误：“”标记之前的语法错误 C:/Python27/include/fileobject.h:46: 错误: '' 之前的语法错误 令牌 C:/Python27/include/fileobject.h:46：警告：类型默认为 int' in declaration of PyFile_AsFile' C:/Python27/include/fileobject.h:46: warning: data definition has no type or storage class C:/Python27/include/fileobject.h:47: error: syntax error before '*' token C:/Python27/include/fileobject.h:48: error: syntax error before '*' token C:/Python27/include/fileobject.h:65: error: syntax error before "FILE" C:/Python27/include/fileobject.h:66: error: syntax error before "FILE" In file included from C:/Python27/include/Python.h:127, from helloworld.c:16: C:/Python27/include/pythonrun.h:35: error: syntax error before '*' token C:/Python27/include/pythonrun.h:36: error: syntax error before '*' token C:/Python27/include/pythonrun.h:38: error: syntax error before '*' token C:/Python27/include/pythonrun.h:39: error: syntax error before '*' token C:/Python27/include/pythonrun.h:40: error: syntax error before '*' token C:/Python27/include/pythonrun.h:45: error: syntax error before '*' token C:/Python27/include/pythonrun.h:55: error: syntax error before '*' token C:/Python27/include/pythonrun.h:61: error: syntax error before '*' token C:/Python27/include/pythonrun.h:78: error: syntax error before '*' token C:/Python27/include/pythonrun.h:152: error: syntax error before '*' token C:/Python27/include/pythonrun.h:154: error: syntax error before '*' token In file included from C:/Python27/include/Python.h:129, from helloworld.c:16: C:/Python27/include/sysmodule.h:12: error: syntax error before '*' token C:/Python27/include/sysmodule.h:12: error: syntax error before "FILE" C:/Python27/include/sysmodule.h:12: warning: type defaults toint' 在 PySys_GetFile' C:/Python27/include/sysmodule.h:12: warning: data definition has no type or storage class In file included from C:/Python27/include/Python.h:131, from helloworld.c:16: C:/Python27/include/import.h:39: error: syntax error before "FILE" helloworld.c: In function__PYX_NAN' 的声明中：helloworld.c:315：警告： 函数memset' helloworld.c: In function __Pyx_PyUnicode_FromString'的隐式声明：helloworld.c:1423：警告：隐式 函数声明strlen' helloworld.c: In function __Pyx_PyObject_AsStringAndSize'：helloworld.c:1474：警告：隐式 声明函数“断言”错误：命令 'C:\MinGW\bin\gcc.exe' 失败，退出状态为 1

正如 IanH 评论的那样，看起来 GCC 未能找到 Python 标头中包含的标准 C 标头，而不是 Cython 的问题。你能不能编译一个简单的C程序，比如下面这个：

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

编译：

$ gcc hello.c -o hello.exe
