title: What may cause alex package build failure?
body: <p>So I was trying to set up a Haskell project (<code>ghcup-hs</code> to be precise) but all attempts at building it, be it just <code>cabal run</code> or using HLS in VSCode, fail at alex package. In the terminal, it says &quot;Building&quot;, my computer gets hot and loud, and then I just have to force quit the virtual machine since nothing is responding.</p>
  <p>I believe it may have something to do with the fact I try to build it on my Ubuntu virtual machine (using Parallels Desktop) but I don't know much about Linux or virtual machines so will be glad to provide any relevant details.</p>
