思路是先将py转换为c代码,然后编译c为so文件,所以要安装以下内容:
python 安装:cython
pip install cython
linux 安装:python-devel,gcc
yum install python-develyum install gcc
初步编译
新建Test.py文件,内容如下
class test: def __init__(self): print('init') def say(self): print ('hello')
新建setup.py,内容如下
from distutils.core import setupfrom Cython.Build import cythonizesetup(ext_modules = cythonize(["Test.py"]))
在bash中执行
python setup.py build_ext
运行后会生成build文件夹,如下
现在so文件就可以像普通py文件一样导入了
集成编译
做了以下内容:
1.文件夹编译
2.删除编译出的.c文件
3.删除编译的temp文件夹
将需要编译的目录和setup.py放在同一层级,执行python setup.py,so文件在build目录下
setup.py代码如下:
