We don't recommend using SML/NJ as a means of <a href="PortingMLton">porting MLton to a new platform</a> or bootstrapping on a new platform. <p> If you do want to build MLton with SML/NJ, it is best to have a binary MLton package installed. If you don't, here are some issues you may encounter when you run <tt>make nj-mlton</tt>. </p> <p> You will get (many copies of) the error message: </p> <pre>/bin/sh: mlton: not found</pre><p> The <tt>Makefile</tt> calls <tt>mlton</tt> to determine dependencies, and can proceed in spite of this error. </p> <p> If you don't have a <tt>mlton</tt> executable, you will get the error message: <pre>Error: cannot upgrade basis because the compiler doesn't work</pre> </p> <p> We use <tt>upgrade-basis.sml</tt> to work around basis library differences, allowing a version of MLton written for a newer basis library to be compiled by an older version of MLton. The file isn't necessary when building with SML/NJ, but is listed in <tt>$(SOURCES)</tt>, so the <tt>Makefile</tt> is attempting to build it. Building <tt>upgrade-basis.sml</tt> requires the old version of MLton to be around so that the right stubs can be built. </p> <p> To work around this problem, do one of the following. </p> <ul> <li> <p> Manually tweak sources to remove $(UP) until you're finished building MLton with SML/NJ and have a working MLton. </p> </li> <li class="gap"> <p> Build <tt>upgrade-basis.sml</tt> on some other machine with a working MLton and copy it over. </p> </li> </ul> <p> If you don't have an <tt>mllex</tt> executable, you will get the error message: <pre>mllex: Command not found</pre> </p> <p> Building MLton requires <tt>mllex</tt> and <tt>mlyacc</tt> 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 (<tt>ml.grm.sml</tt>, <tt>ml.grm.sig</tt>, <tt>ml.lex.sml</tt>, <tt>mlb.grm.sig</tt>, <tt>mlb.grm.sml</tt>). </p> </div> <p> <hr> Last edited on 2006-10-19 17:06:01 by <span title="ppp-71-139-198-88.dsl.snfc21.pacbell.net"><a href="StephenWeeks">StephenWeeks</a></span>. </body></html>
