title: How to update GLIBC_2.17 in CentOS
body: <p>After unpacking the  kingsoft-office_9.1.0.4032~a10_x86.tar, I run the "et", but the terminal telled me that</p>
  
  <pre><code> /king/kingsoft-office_9.1.0.4032~a10_x86/office6/et: /lib/libc.so.6: version `GLIBC_2.17' not found (required by /king/kingsoft-office_9.1.0.4032~a10_x86/office6/libstdc++.so.6)
  </code></pre>
  
  <p>then follwing the tip, I download the deb from <a href="http://community.wps.cn/wiki/Libstdc%2B%2B_too_old" rel="nofollow">http://community.wps.cn/wiki/Libstdc%2B%2B_too_old</a>, and operated as what the website says, anyway, the same question still occurs</p>
