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

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

In case, someone else encounters the same issue,

I had updated the glibc and somehow the old ldconfig had been flushed was facing this error while running the application

> error while loading shared libraries: libjson-c.so.2: cannot open shared object file: No such file or directory

Even after setting the LD_LIBRARY_PATH it didn't work:

LD_LIBRARY_PATH=/usr/local/lib
export LD_LIBRARY_PATH

Finally the commands below came to the rescue.

// Add you library path here.
echo /usr/local/lib >> /etc/ld.so.conf

// And then Run ldconfig to reflect the path
ldconfig

The order of the accepted answer doesn't work for me.

I followed some tips in the comments and here's what I tried and succceded in my fresh install CentOS 7.2

1. From @lkraav's comment, I followed this wiki https://wiki.centos.org/AdditionalResources/Repositories/DebugInfo and create a new file.

> The following could be appended to /etc/yum.repos.d/CentOS-Base.repo or a new file created such as /etc/yum.repos.d/CentOS-Debug.repo.

2. I pasted those contents from the wiki into the new /etc/yum.repos.d/CentOS-Debug.repo file but edit enabled=0 line to enabled=1

3. I debuginfo-install everything showed in the gdb warning and succeeded installing.
