gdb - Missing separate debuginfos, use: debuginfo-install glibc-2.12-1.47.el6_2.9.i686 libgcc-4.4.6-3.el6.i686 libstdc++-4.4.6-3.el6.i686

Question

CentOS 6.2 + GNU gdb (GDB) Red Hat Enterprise Linux (7.2-50.el6)

When I debug a simple c++ code with GDB, I saw the following warning:

Missing separate debuginfos, use: debuginfo-install glibc-2.12-1.47.el6_2.9.i686 libgcc-4.4.6-3.el6.i686 libstdc++-4.4.6-3.el6.i686

I have tried the following methods and none of them fix the problems:

1. Search SO

2. yum install glibc

3. debuginfo-install glibc-2.12-1.47.el6_2.9.i686 libgcc-4.4.6-3.el6.i686 libstdc++-4.4.6-3.el6.i686

In fact, when I install those RPM one by one, I just realized that they are installed already.

[root@localhost Excluded]# rpm -ivh glibc-2.12-1.47.el6_2.9.i686.rpm

Why GDB cannot find it?

Question: Do I have to worry about this issue? If not, how to turn it off? If yes, how to fix it?

Thank you

debuginfo-install is a command of yum-utils, so

1. yum install yum-utils
2. debuginfo-install glibc
3. if the warning's still there, edit /etc/yum.repos.d/CentOS-Debuginfo.repo, set enabled=1
