title: What does version info in ldd -v mean?
body: <pre><code>Version information:
      /usr/lib/lapack/liblapack.so:
          libc.so.6 (GLIBC_2.14) =&gt; /lib/x86_64-linux-gnu/libc.so.6
          libc.so.6 (GLIBC_2.4) =&gt; /lib/x86_64-linux-gnu/libc.so.6
          libc.so.6 (GLIBC_2.2.5) =&gt; /lib/x86_64-linux-gnu/libc.so.6
          libgcc_s.so.1 (GCC_4.0.0) =&gt; /lib/x86_64-linux-gnu/libgcc_s.so.1
          libgfortran.so.3 (GFORTRAN_1.0) =&gt; /usr/lib/x86_64-linux-gnu/libgfortran.so.3
          libgfortran.so.3 (GFORTRAN_1.4) =&gt; /usr/lib/x86_64-linux-gnu/libgfortran.so.3
          libm.so.6 (GLIBC_2.2.5) =&gt; /lib/x86_64-linux-gnu/libm.so.6
  </code></pre>
  
  <p>So there are 3 rows of <code>libc.so.6</code>, versioned at <code>GLIBC_2.xx</code>.</p>
  
  <p>What does that mean? What version of libc.so.6 does this <code>liblapack.so</code> require?</p>
  
  <p>How can I get <code>liblapack.so</code>'s version?</p>
