title: Installing Big Integer libraries for C++?
body: <p>I try to install <a href="https://mattmccutchen.net/bigint/" rel="nofollow">https://mattmccutchen.net/bigint/</a> and even when I include all the .hh files, using BigIntegers throws undefined reference errors.</p>
  
  <pre><code>[Linker error] undefined reference to `BigInteger::BigInteger(int)'
  [Linker error] undefined reference to BigInteger::divideWithRemainder(BigInteger const&amp;, BigInteger&amp;)
  </code></pre>
  
  <p>I am using DevCPP and don't want to switch from this (it's been a headache getting anything other than DevCPP working). I also tried GMP but that was needlessly confusing and I couldn't get that working either.</p>
  
  <p>When I tried compiling the <code>.cc</code> files that came with it, I get all the same linker errors. </p>
