【问题描述】：
这可能是一个新手问题。当完全相同的代码在 linux 上运行时，我无法对简单的 helloworld.pyx 教程脚本进行 cythonize：
print("hello world")
这里是 setup.py 脚本：
from distutils.core import setup
from Cython.Build import cythonize
setup(ext_modules = cythonize('helloworld.pyx'))
但我在运行 python setup.py build_ext --inplace 后得到了这个：
running build_ext
building 'helloworld' extension
creating build
creating build/temp.macosx-10.7-x86_64-3.6
gcc -Wno-unused-result -Wsign-compare -Wunreachable-code -DNDEBUG -g -fwrapv -O3 -Wall -Wstrict-prototypes -I/Users/haotian/anaconda3/include -arch x86_64 -I/Users/haotian/anaconda3/include -arch x86_64 -I/Users/haotian/anaconda3/include/python3.6m -c helloworld.c -o build/temp.macosx-10.7-x86_64-3.6/helloworld.o

我使用的是 MacOS 10.13.1、python 3.6.3、Cython 0.27.3 和 clang-900.0.38。
显然包含 stdint.h 存在问题，我应该如何在 Cython 中进行呢？
编辑： 我的 gcc 在 /usr/bin/gcc
gcc --version
显示：
Configured with: --prefix=/Applications/Xcode.app/Contents/Developer/usr --with-gxx-include-dir=/usr/include/c++/4.2.1

【问题讨论】：
-
你确定你使用的是clang而不是gcc吗？你的gcc是哪个版本的，如果日志可信的话用哪个？
-
helloworld.c 可能不包含
#include <stdint.h>。或者，你被困在“垃圾模式”，又名 gnu90。将-std=c99或-std=c11传递给gcc 编译器。 -
我修改了版本号@ead
-
看起来clang“假装”是gcc并使用相当老的gcc-headers（4.2.1）。您应该直接使用 clang（将 CC 环境变量设置为 clang）或安装更新的 gcc 版本
-
设置 CC 似乎不起作用，我尝试手动运行 gcc-7:
/usr/local/bin/gcc-7 -Wno-unused-result -Wsign-compare -Wunreachable-code -DNDEBUG -g -fwrapv -O3 -Wall -Wstrict-prototypes -I/Users/haotian/anaconda3/include -arch x86_64 -I/Users/haotian/anaconda3/include -arch x86_64 -I/Users/haotian/anaconda3/include/python3.6m -c helloworld.c -o build/temp.macosx-10.7-x86_64-3.6/helloworld.o这也给了我同样的错误
