Python 项目转化为so文件实例

pip install cython

yum install python-devel
yum install gcc

class test:
  
  def __init__(self):
    print('init')

  def say(self):
    print ('hello')

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

setup(ext_modules = cythonize(["Test.py"]))

python setup.py build_ext

"""
执行前提：
  系统安装python-devel 和 gcc
  Python安装cython

编译整个当前目录：
  python py-setup.py
编译某个文件夹：
  python py-setup.py BigoModel

生成结果：
  目录 build 下

生成完成后：
  启动文件还需要py/pyc担当，须将启动的py/pyc拷贝到编译目录并删除so文件
