My knowledge was apparently outdated! So, the bug I was thinking of was <a href="https:&#x2F;&#x2F;github.com&#x2F;rust-lang&#x2F;rust&#x2F;issues&#x2F;28667" rel="nofollow">https:&#x2F;&#x2F;github.com&#x2F;rust-lang&#x2F;rust&#x2F;issues&#x2F;28667</a> , which has apparently since been closed. The Alpine tracker also links to this bug: <a href="https:&#x2F;&#x2F;bugs.alpinelinux.org&#x2F;issues&#x2F;3949" rel="nofollow">https:&#x2F;&#x2F;bugs.alpinelinux.org&#x2F;issues&#x2F;3949</a><p>And in fact, <a href="https:&#x2F;&#x2F;doc.rust-lang.org&#x2F;book&#x2F;advanced-linking.html#linux" rel="nofollow">https:&#x2F;&#x2F;doc.rust-lang.org&#x2F;book&#x2F;advanced-linking.html#linux</a> has some instructions for building your own rustc in this way.<p>I am not sure why we don&#x27;t currently distribute them today, though... I will ask around.<p>EDIT: Alex says:<p><pre><code>  we don&#x27;t have an issue for it 
  specifically, no, but I think all alpine users were 
  trying to use the llvm on the system

  b&#x2F;c we don&#x27;t work well with building an llvm against 
  musl right now
</code></pre>
So, yeah, some small things to work out with regards to Alpine.
