py文件转换为so文件

将py文件编译为so文件

利用上面代码生成so文件生成的文件不方便取放，名字也不一样

通过执行发现转换执行了下面三句

/usr/local/python3/bin/cython test.py
gcc -pthread -Wno-unused-result -Wsign-compare -DNDEBUG -g -fwrapv -O3 -Wall -fPIC -I/usr/local/python3/include/python3.7m -c test.c -o test.o
gcc -pthread -shared test.o -o test.so

通过命令行执行也可以生成，那么开始编写一个shell脚本

import datetime
import os

'''
/usr/local/python3/bin/cython test.py
gcc -pthread -Wno-unused-result -Wsign-compare -DNDEBUG -g -fwrapv -O3 -Wall -fPIC -I/usr/local/python3/include/python3.7m -c test.c -o test.o
gcc -pthread -shared test.o -o test.so

通过代码生成一个shell脚本，再去执行这个脚本，达到生成一样目录结构的so文件目录

执行完后生成的sh文件

#!/bin/bash

mkdir encryp_so20230309145220

/usr/local/python3/bin/cython te.py

gcc -pthread -Wno-unused-result -Wsign-compare -DNDEBUG -g -fwrapv -O3 -Wall -fPIC -I/usr/local/python3/include/python3.7m -c te.c -o te.o

gcc -pthread -shared te.o -o te.so

find . -name '*.c' -delete
find . -name '*.o' -delete

mkdir encryp_so20230309145220/bbb

mv te.so encryp_so20230309145220/te.so
cp __init__.py encryp_so20230309145220/__init__.py

直接执行该文件即可得到想要的so文件
