Centos 6.x 上升级go 1.10.3

前提

目前本地Linux (Centos 6.x) 编译环境还滞留在1.8.x上，为了提升go性能，想将go升级到最新版，但在升级过程中遇到如下问题，故此记录下！忘后续的go友能跳过此坑！

问题描述

在Centos 6.x 升级go 1.10.x过程中遇到如下问题：

step1. 下载go 1.10.x 源码
step2. 解压，进入go/src
step3. 执行./all.bash

Building Go cmd/dist using /root/go1.4.
Building Go toolchain1 using /root/go1.4.
Building Go bootstrap cmd/go (go_bootstrap) using Go toolchain1.
Building Go toolchain2 using go_bootstrap and Go toolchain1.
Building Go toolchain3 using go_bootstrap and Go toolchain2.
Building packages and commands for linux/amd64.

问题分析

为什么在执行binutils_test.go 会Failed，最终查看代码原因是因为如下命令引起：

1	120807 3650 execve("/usr/bin/addr2line", ["/usr/bin/addr2line", "-aif", "-e", "testdata/exe_linux_64"], [/* 15 vars */] <unfinished ...>

有关生成此命令的源代码可查看如下地址：addr2line

add2line文件来自于包：binutils

执行命令失败，是因为在CentOS 6.x上，binutils的版本是2.20，参考文献，然后addr2line命令中的-a参数在binutils 2.21版中才添加

因此，为了解决这个问题，我从源码重新进行编译binutils并将其构建的二进制文件添加到PATH中，然后运行测试，并成功通过。

编译安装binutils过程如下：

wget https://ftp.gnu.org/gnu/binutils/binutils-2.27.tar.gz
tar zxvf binutils-2.27.tar.gz 
cd binutils-2.27
./configure --prefix=/usr
make 
make install

特此说明，在Centos 7.x 上能成功避免此坑！！
