title: Undefined reference to mempcy@GLIBC_2.14 when compiling on Linux
body: <p>I am trying to port an application to drive a device that uses an ftdi2332h chip from windows to linux. I installed the libftd2xx library on an ubuntu 10.04 system <a href="http://www.ftdichip.com/Drivers/D2XX/Linux/ReadMe-linux.txt" rel="noreferrer">per these instructions</a>. </p>
  
  <p>When I try to compile any of the sample programs I get the following error:</p>
  
  <pre><code>/usr/local/lib/libftd2xx.so: undefined reference to `memcpy@GLIBC_2.14'
  collect2: ld returned 1 exit status
  </code></pre>
  
  <p>Any guidelines on how to fix this?</p>
