1，在运行GDB的R指令时，报错。。。。

(gdb) r

Starting program: /root/tst

Breakpoint 1, main () at tst.c:17

17              long result=0;

Missing separate debuginfos, use: debuginfo-install glibc-2.12-1.80.el6_3.6.x86_64

2，按提示，运行debuginfo-install glibc-2.12-1.80.el6_3.6.x86_64时报错：

debuginfo-install glibc-2.12-1.80.el6_3.6.x86_64

3，网上搜索，找到有用的。

For this to work, you need to have the debuginfo repository defined.  For CentOS 5, put the following in /etc/yum.repos.d/CentOS-Base-debuginfo.repo:

[base-debuginfo]name=CentOS-$releasever -DebugInfobaseurl=http://debuginfo.centos.org/$releasever/$basearch/gpgcheck=0enabled=0protect=1priority=1 ~~~~~~~ debuginfo-install is part of the yum-utils package.  If you don't know what package contains a command, you can try something like yum install /usr/bin/debuginfo-install and yum will find it for you (assuming that the package you want is in /usr/bin) ~~~~~~~~ 4，问题解决
