title: [AWS Lambda]: How to fix "/lib64/libm.so.6: version `GLIBC_2.29' not found"
body: <p>I'm attempting to use <a href="https://www.lcdf.org/gifsicle/" rel="nofollow noreferrer">gifsicle</a> in a lambda function utilizing a Node.js 14.x runtime. Executing the function throws the following error:</p>
  <pre><code>ERROR /opt/gifsicle: /lib64/libm.so.6: version `GLIBC_2.29' not found (required by /opt/gifsicle)
  </code></pre>
  <p>After doing some due diligence, I believe I need to add a layer to my lambda that contains the directory and required dependency noted in the error - but I'm at a total loss as to how to go about doing so.</p>
  <p>Any suggestions?</p>
