body: <p>When I execute <code>make</code> from the <a href="http://dpdk.org/doc/quick-start" rel="noreferrer">quick start</a> instruction for DPDK, I get the following error:</p>
  
  <pre><code>eal_memory.c:56:18: fatal error: numa.h: No such file or directory
  </code></pre>
  
  <p>The error comes out even when libnuma is installed already:</p>
  
  <pre><code>&gt;sudo yum install numactl-libs.x86_64
  Loaded plugins: fastestmirror, langpacks
  Loading mirror speeds from cached hostfile
   * elrepo: mirrors.tuna.tsinghua.edu.cn
  Package numactl-libs-2.0.9-6.el7_2.x86_64 already installed and latest version
  Nothing to do
  </code></pre>
  
  <p>I'm using CenOS Linux release 7.3.1611 (Core).</p>
  
  <p>How do I fix this problem?</p>
