场景说明：RedHat6.4

    在gdb调试boost库的时候，出现如下的错误：

Program received signal SIGSEGV,Segmentation fault.

0x0011c613 in boost::thread::start_thread()()

  from /usr/local/lib/libboost_thread.so.1.49.0

Missing separate debuginfos, use:debuginfo-install glibc-2.12-1.80.el6.i686 libgcc-4.4.6-4.el6.i686 libstdc++-4.4.6-4.el6.i686

一言以蔽之，该指令和yum一样安装一些库文件，但是安装的库文件是携带gdb的调试。如下是debuginfo提供的源，如果debuginfo-install下载缓慢，可以直接使用迅雷下载：

解决方案：

1）配置debuginfo的yum源，CentOS可能自带：

# 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 - Debuginfo

baseurl=http://debuginfo.centos.org/6/$basearch/

gpgcheck=1

gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-Debug-6

enabled=1

保存文件到/etc/yum.repos.d/目录下，名字：CentOS-Debug.repo  

2)测试是否已经安装了debuginfo-install

debuginfo-install glibc

如果出现下面的问题,表明没有安装：

-bash: debuginfo-install: command not found

3）安装yum-utils，使用命令：

yum install yum-utils

可能安装的软件包比较多，可以单独安装：

# yum install nss-softokn-debuginfo --nogpgcheck

--nogpgcheck参数选项：忽略签名的检查

4）使用debuginfo-install指令，下载上面缺乏的调试库
