在centos7上面gdb调试程序时候，报错信息是：
Missing separate debuginfos, use: debuginfo-install glibc-2.17-157.el7_3.5.x86_64
解决方案：
1 先修改"/etc/yum.repos.d/CentOS-Debuginfo.repo"文件的 enable=1；有时候该文件不存在，则需要手工创建此文件并加入以下内容：
[debug]
name=CentOS-7 - Debuginfo
baseurl=http://debuginfo.centos.org/7/$basearch/
gpgcheck=1
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-Debug-7
enabled=1
2 执行 sudo yum install -y glibc
3 执行 debuginfo-install glibc文章来源：https://www.toymoban.com/news/detail-603284.html
