Yes coming from nixos, this &quot;foo install me tools; bar build me project&quot; ideom is quite primitive. I have an long-open RFC that I hope will get cross-compilation working the right way <a href="https:&#x2F;&#x2F;github.com&#x2F;rust-lang&#x2F;rfcs&#x2F;pull&#x2F;1133" rel="nofollow">https:&#x2F;&#x2F;github.com&#x2F;rust-lang&#x2F;rfcs&#x2F;pull&#x2F;1133</a>.<p>That said RustUP is still a fine easy way to get <i>compilers</i> builds as opposed to standard library builds. I view it as convenient duck-tape analogous to Haskell&#x27;s stack in that regard.
