问题
编译程序时遇到问题：
/bin/ld: this linker was not configured to use sysroots
collect2: error: ld returned 1 exit status
解决
- 升级
binutils
分析
查询了一下，这篇文章 提到该问题的原因是在编译安装ld时没有配置sysroot参数。
那么可能的解决方式是重新安装ld链接器。
查看一下ld的版本。这里采用的方式是查找能够提供ld的程序包：
[root: ~]# yum whatprovides ld
Loaded plugins: fastestmirror
Repository epel is listed more than once in the configuration
Repository epel-debuginfo is listed more than once in the configuration
Repository epel-source is listed more than once in the configuration
base | 3.6 kB 00:00:00
epel | 4.7 kB 00:00:00
extras | 2.9 kB 00:00:00
updates | 2.9 kB 00:00:00

binutils-2.25.1-22.base.el7.x86_64 : A GNU collection of binary utilities

Filename : /bin/ld
binutils-2.25.1-22.base.el7.x86_64 : A GNU collection of binary utilities
Repo : installed
Matched from:
Filename : /usr/bin/ld
查询结果说明当前的ld链接器版本为2.25.1-22，并非最新版本 2.27-43。
受此启发，更新一下binutils：
[root: ~]# yum upgrade binutils
Loaded plugins: fastestmirror
