31<div class="paragraph"><p>You can compile MLton with <a href="SMLNJ">SML/NJ</a>, however the resulting\r
32compiler will run much more slowly than MLton compiled by itself. We\r
33don&#8217;t recommend using SML/NJ as a means of\r
34<a href="PortingMLton">porting MLton</a> to a new platform or bootstrapping on a\r
35new platform.</p></div>\r
36<div class="paragraph"><p>If you do want to build MLton with SML/NJ, it is best to have a binary\r
37MLton package installed. If you don&#8217;t, here are some issues you may\r
38encounter when you run <span class="monospaced">make smlnj-mlton</span>.</p></div>\r

50proceed in spite of this error.</p></div>\r

58distributed with a binary package of MLton. The easiest solution is\r
59to copy the front-end lexer/parser files from a different machine\r
