gdb调试时的问题Missing separate debuginfos, use: debuginfo-install glibc-XXX
转载自：http://blog.csdn.net/testcs_dn/article/details/19565411
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：
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：保存之后，使用 debuginfo-install glibc-2.12-1.132.el6.i686 安装，输出如下：
- # 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

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。
