title: Install tcmalloc on CentOS
body: <p>I installed <code>tcmalloc</code> on CentOS using the command:</p>
  
  <pre><code>sudo yum install google-perftools
  </code></pre>
  
  <p>And it proceeds correctly. But I cannot find any installed perftools libraries in <code>/usr/lib/</code>, so I cannot set <code>LD_PRELOAD</code> variable. </p>
  
  <p>Then, when I tried to compile with flag <code>-ltcmalloc</code>, the compiler did not recognize it, which quite made sense.</p>
  
  <p>What else should I specify to use <code>tcmalloc</code> on CentOS? Thanks.</p>
