GDB Debugging problems: Missing separate Debuginfos, use ...

When using GDB for debugging under CentOS6.4,

When you use the BT (breaktrace) command, the following prompts are displayed:

First day Tip:

Missing separate Debuginfos, Use:debuginfo-install glibc-2.12-1.107.el6.i686

The problem is not resolved, the next day prompt:

Missing separate Debuginfos, Use:debuginfo-install glibc-2.12-1.132.el6.i686

However, when prompted to use Debuginfo-install glibc-2.12-1.132.el6.i686 to install the information will be reported as follows:

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 the new repos for mirrors

No Debuginfo packages available to install

To install using Yum:

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

But prompted: 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.

Using the Yum install glibc installation, found that only some basic libraries were installed, not including Glibc-debuginfo

Later search found that you need to modify the "/etc/yum.repos.d/centos-debuginfo.repo" file first enable=1

The contents of the document are as follows:

# Centos-debug.repo # The  
Mirror system uses the connecting IP address of the client and the  
# Update status of each mirror to pick mirrors, are updated to and  
# geographically close to the client.  You are should use this for CentOS updates # unless to are manually other picking  
.  
# all  
      
Debug Packages various CentOS-5 releases  
# are to a single merged, split by Repo 10/>#  
# Note:packages in the Debuginfo repo are currently not signed  
#

After saving, use the Debuginfo-install glibc-2.12-1.132.el6.i686 installation, the output is as follows:
