golang 从源码编译记录

下载golang 源码

git clone https://github.com/golang/go.git

笔者写此博客的时候最新是go 1.10.1 版本。 源码目录 /root/source_bk/go_source/go

基本编译流程解释

go 语言编译器自1.5版本开始自举 （ 使用go编译器编译go编译器 ） 。所以最新的源码编译其实是直接使用go 编译器来编译。

嗯 所以为了编译go编译器你要先有go 编译器

所以从源码起步，编译的go编译器的方式是

• 先编译go 1.4+版本 （ 没有自举， 使用c编译器编译）
• 然后使用编译好的go 1.4+编译器来编译最新的源码。

编译 go 1.4.3版本

• 切换源码到1.4.3版本

git checkout -b go143 go1.4.3

• 编译 1.4.3 版本

cd src && ./all.bash

• 保存go 1.4.3 版本并维护全局变量

cp -r /root/source_bk/go_source/go ~/go1.4
export GOROOT_BOOTSTRAP=~/go1.4

编译 go 1.10.1 版本

• 切换源码到最新

git checkout master

• 清理刚刚编译的残余

git status # 然后将新增的文件一一删除

• 编译

cd src && ./all.bash

输出日志

从编译日志可以清晰的看出两个版本的编译区别 :)
