Boost Python C++ 学习 笔记

教程
https://www.boost.org/doc/libs/1_76_0/libs/python/doc/html/tutorial/tutorial/functions.html

1. 编写greet.cpp(hello_ext指代module hello_ext 可修改) 文件
2. 编写 Makefile文件

   hello_ext.so : greet.o
   g++ -shared greet.o -o hello_ext.so -lpython3.8 -lboost_python38
   greet.o : 
   g++ -c -fPIC -I/usr/include/python3.8 greet.cpp -o greet.o

   测试如下(example 2):
