Could not find debuginfo for main pkg
<p>I'm trying to use gdb with my code, but it's giving me an error:</p>

<pre><code>Missing separate debuginfos, use: debuginfo-install
blas-3.2.1-4.el6.x86_64 libtool-ltdl-2.2.6-15.5.el6.x86_64
</code></pre>

<p>Trying to install the missing packages, but getting another error:</p>

<pre><code># debuginfo-install blas-3.2.1-4.el6.x86_64 libtool-ltdl-2.2.6-15.5.el6.x86_64

<p>I downloaded a package, but when trying to install in manually, it says it's already installed:</p>

<pre><code>$ sudo rpm -ivh blas-3.2.1-4.el6.x86_64.rpm

</code></pre>

<p>The OS is CentOS 6.7. Just in case, my /etc/yum.repos.d/CentOS-Debuginfo.repo currently:</p>

<pre><code>[base-debuginfo]
name=CentOS-6 - Debuginfo
baseurl=http://debuginfo.centos.org/6/$basearch/
gpgcheck=0
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-Debug-6

</code></pre>

<p>Any ideas? 
Thanks in advance.</p>
