gdb调试时的问题Missing separate debuginfos, use: debuginfo-install glibc-XXX

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-packagekit
Loading mirror speeds from cached hostfile
 * base: mirrors.yun-idc.com
 * extras: mirrors.yun-idc.com
 * updates: mirrors.yun-idc.com
Checking for new repos for mirrors
No debuginfo packages available to install

使用yum来进行安装：

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.

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- releases
    # are merged into a single repo, split by BaseArch
    #
    # Note: packages in the debuginfo repo are currently not signed
    #  

    [debug]
    name=CentOS- - Debuginfo
    baseurl=http://debuginfo.centos.org/6/$basearch/
    gpgcheck=
    gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-Debug-6
    enabled=  

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

    Complete!  

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。
