准备工作

1. 配置编译环境

   • 安装gcc, make, g++
   • 安装GCC toolchain

   apt-get install build-essential

   • 安装编译库

   libssl-dev zlib1g-dev libncurses5-dev libncursesw5-dev libreadline-dev libsqlite3-dev libgdbm-dev libdb5.3-dev libbz2-dev libexpat1-dev liblzma-dev tk-dev libffi-dev

2. 编译参数

   • 设置编译后文件安装位置，默认/usr/

   prefix --- Python模块位置， ${prefix}/lib/pythonversion
   exec_prefix --- Python执行位置，${exec_prefix}/bin/python3
   默认prefix与exec_prefix相同

   • 使用优化的设置进行编译

   configure --enable-optimizations

   • 启用Link Time Optimization

   --with-lto, LTO当构建最终的可执行文件或共享库以获得额外的性能收益时，LTO利用最近编译器工具链的优势，跨越任意的.o文件边界进行优化。

3. 编译安装

   • 并存安装

   If you intend to install multiple versions using the same prefix you must decide which version (if any) is your "primary" version. Install that version using make install. Install all other versions using make altinstall.

   • 安装

   make -j n n为指定的编译线程数
   make install
