背景：试着在centos7里调试一下c程序，出现，Missing separate debuginfos, use: debuginfo-install cyrus-sasl-lib-2.1.26-17.el7.x86_64 glibc-2.17-78.el7.x86_64 keyutils-libs-1.5.8-3.el7.x86_64 krb5-libs-1.12.2-14.el7.x86_64 libcom_err-1.42.9-7.el7.x86_64 libgcc-4.8.3-9.el7.x86_64 libselinux-2.2.2-6.el7.x86_64 libstdc++-4.8.3-9.el7.x86_64 nss-softokn-freebl-3.16.2.3-9.el7.x86_64 openssl-libs-1.0.1e-42.el7.4.x86_64 xz-libs-5.1.2-9alpha.el7.x86_64

问题：

Missing separate debuginfos, use: debuginfo-install glib

解决方法：

在CentOS6.5上用gdb调试时提示Missing separate debuginfos, use: debuginfo-install glibc-2.12-1.132.el6.i686

实践如下过程：

uname -rsp

Linux 3.10.0-229.1.2.el7.x86_64 x86_64

http://debuginfo.centos.org/7/x86_64/

（例如本机uname -r 3.10.0-229.1.2 只能选 kernel-debuginfo-3.10.0-229.1.2.el7.x86_64.rpm kernel-debuginfo-common-x86_64-3.10.0-229.1.2.el7.x86_64.rpm

）

安装debuginfo

rpm -ivh kernel-debuginfo-3.10.0-229.1.2.el7.x86_64.rpm

rpm -ivh kernel-debuginfo-common-x86_64-3.10.0-229.1.2.el7.x86_64.rpm

配置yum源

or this to work, you need to have the debuginfo repository defined. For CentOS 5, put the following in /etc/yum.repos.d/CentOS-Base-debuginfo.repo:

[base-debuginfo] name=CentOS-$releasever - DebugInfo baseurl=http://debuginfo.centos.org/$releasever/$basearch/ gpgcheck=0

enabled=0

protect=1

priority=1

利用debuginfo-install安装glibc

debuginfo-install glibc

注意事项

安装debuginfo 去http://debuginfo.centos.org寻找和你内核完全匹配的rpm包。
