cython，编译错误（调用C函数）

Question

我尝试调用c库，例如下面的示例。你知道吗

# demo.pyx
from libc.math cimport sin

cdef double f(double x):
    return sin(x*x)

你知道吗设置.py你知道吗

# setup.py
from distutils.core import setup
from distutils.extension import Extension
from Cython.Build import cythonize

ext_modules=[
    Extension("demo",
              sources=["demo.pyx"],
              libraries=["m"] # Unix-like specific
    )
]

setup(
  name = "Demos",
  ext_modules = cythonize(ext_modules)
)

跑设置.py如下所示

%run setup.py build_ext --inplace --compiler=msvc

但是，出现以下错误：

    running build_ext
building 'demo' extension
