覆盖Distutils的默认编译标志

Question

如何在Python3 setup.py脚本中删除或更改“distutils”使用的默认编译标志？

有时候，有一些我不想使用distutils的编译器标志。

对于这个问题，我正在寻找一个答案要么强制使用一组编译器标志（即我设置的那些），或删除distutils想要使用的标志。

我的代码：

#!/usr/bin/env python3
# python3 setup.py build_ext --inplace
"""Distutils setup file for building C-based modules"""

from distutils.core import Extension, setup

    '-fdata-sections',

setup(
    name='chemistry',
    version=__version__,
    description='Chemistry-related Functions',
    author=__author__,
    author_email=__email__,
    maintainer=__author__,

    ext_modules=[Extension(

        sources=['pychemistry.c', 'chemistry.c'],
        extra_compile_args=COMPILE_ARGS,
    )],
)

setup.py的当前输出：
