在CentOS6.4下使用gdb进行调试的时候，

使用bt(breaktrace)命令时，会弹出如下的提示：

头一天提示：

Missing separate debuginfos, use: debuginfo-install glibc-2.12-1.107.el6.i686

问题没解决，第二天提示：

Missing separate debuginfos, use: debuginfo-install glibc-2.12-1.132.el6.i686

但是直接按提示使用 debuginfo-install glibc-2.12-1.132.el6.i686 去安装的时候会报如下的信息：

Loaded plugins: fastestmirror, refresh-packagekitLoading mirror speeds from cached hostfile * base: mirrors.yun-idc.com * extras: mirrors.yun-idc.com * updates: mirrors.yun-idc.comChecking for new repos for mirrorsNo debuginfo packages available to install

使用yum来进行安装：

 sudo yum --nogpgcheck --enablerepo=debug install glibc-debuginfo

却提示：Error Downloading Packages:  glibc-debuginfo-common-2.12-1.132.el6.i686: failure: glibc-debuginfo-common-2.12-1.132.el6.i686.rpm from debug: [Errno 256] No more mirrors to try.

使用yum install glibc安装，发现只是安装了一些基本库，不包含 glibc-debuginfo

后来搜索发现需要先修改“/etc/yum.repos.d/CentOS-Debuginfo.repo”文件的enable=1

文件内容如下：

# CentOS-Debug.repo## The mirror system uses the connecting IP address of the client and the# update status of each mirror to pick mirrors that are updated to and# geographically close to the client.  You should use this for CentOS updates# unless you are manually picking other mirrors.## All debug packages from all the various CentOS-5 releases# are merged into a single repo, split by BaseArch## Note: packages in the debuginfo repo are currently not signed#[debug]name=CentOS-6 - Debuginfobaseurl=http://debuginfo.centos.org/6/$basearch/gpgcheck=1gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-Debug-6enabled=1

保存之后， 使用  debuginfo-install glibc-2.12-1.132.el6.i686  安装，输出如下：

OK，问题解决。

第二次安装总结：

1、需要先修改“/etc/yum.repos.d/CentOS-Debuginfo.repo”文件的enable=1；

2、使用 sudo yum install glibc 安装；

3、使用 debuginfo-install glibc-2.12-1.132.el6.i686 安装。

测试，安装成功。
