<p>You can compile MLton with <a href="SMLNJ">SML/NJ</a>, however the resulting
compiler will run much more slowly than MLton compiled by itself.  We
don&#8217;t recommend using SML/NJ as a means of
<a href="PortingMLton">porting MLton</a> to a new platform or bootstrapping on a
new platform.</p>
</div>
<div class="paragraph">
<p>If you do want to build MLton with SML/NJ, it is best to have a binary
MLton package installed.  If you don&#8217;t, here are some issues you may
encounter when you run <code>make smlnj-mlton</code>.</p>
</div>
<div class="paragraph">
<p>You will get (many copies of) the error messages:</p>
</div>
<div class="listingblock">
<div class="content">
<pre>/bin/sh: mlton: command not found</pre>
</div>
</div>
<div class="paragraph">
<p>and</p>
</div>
<div class="listingblock">
<div class="content">
<pre>make[2]: mlton: Command not found</pre>
</div>
</div>
<div class="paragraph">
<p>The <code>Makefile</code> calls <code>mlton</code> to determine dependencies, and can
proceed in spite of this error.</p>
</div>
<div class="paragraph">
<p>If you don&#8217;t have an <code>mllex</code> executable, you will get the error
message:</p>
</div>
<div class="listingblock">
<div class="content">
<pre>mllex: Command not found</pre>
</div>
</div>
<div class="paragraph">
<p>Building MLton requires <code>mllex</code> and <code>mlyacc</code> executables, which are
distributed with a binary package of MLton.  The easiest solution is
to copy the front-end lexer/parser files from a different machine
(<code>ml.grm.sml</code>, <code>ml.grm.sig</code>, <code>ml.lex.sml</code>, <code>mlb.grm.sig</code>,
<code>mlb.grm.sml</code>).</p>
