This is a tree of Makefiles which when invoked downloads the source code, builds a package and installs it on the system. In order to run MLton on NetBSD, you will have to install several packages for it to work: </p> <ul> <li> <p> <tt>shells/bash</tt> </p> </li> <li class="gap"> <p> <tt>devel/gmp</tt> </p> </li> <li class="gap"> <p> <tt>devel/gmake</tt> </p> </li> </ul> <p> In order to get graphical call-graphs of profiling information, you will need the additional package </p> <ul> <li> <p> <tt>graphics/graphviz</tt> </p> </li> </ul> <p> To build the documentation for MLton, you need <tt>htmldoc</tt>. </p> <h2 id="head-94491c2cf063e8b634a4582f510f3a6735669262">Tips for compiling and using MLton on NetBSD</h2> <p> MLton can be a memory-hog on computers with little memory. While 640Mb of RAM ought to be enough to self-compile MLton one might want to do some tuning to the NetBSD VM subsystem in order to succeed. The notes presented here is what <a href="JesperLouisAndersen">JesperLouisAndersen</a> uses for compiling MLton on his laptop. </p> <h3 id="head-3bf1043eef710e5b57c1d91fccdbbd6535c8e3e0">The NetBSD VM subsystem</h3> <p> NetBSD uses a VM subsystem named <a class="external" href="http://www.ccrc.wustl.edu/pub/chuck/tech/uvm/"><img src="moin-www.png" alt="[WWW]" height="11" width="11">UVM</a>. <a class="external" href="http://www.selonen.org/arto/netbsd/vm_tune.html"><img src="moin-www.png" alt="[WWW]" height="11" width="11">Tuning the VM system</a> can be done via the <tt>sysctl(8)</tt>-interface with the "VM" MIB set. </p> <h3 id="head-53250437dad54a0be46b79ac843e8ef296be4249">Tuning the NetBSD VM subsystem for MLton</h3> <p> MLton uses a lot of anonymous pages when it is running. Thus, we will need to tune up the default of 80 for anonymous pages. Setting </p> <pre>sysctl -w vm.anonmax=95 sysctl -w vm.anonmin=50 sysctl -w vm.filemin=2 sysctl -w vm.execmin=2 sysctl -w vm.filemax=4 sysctl -w vm.execmax=4 </pre><p> makes it less likely for the VM system to swap out anonymous pages. For a full explanation of the above flags, see the documentation. </p> <p> The result is that my laptop goes from a MLton compile where it swaps a lot to a MLton compile with no swapping. </p> </div> <p> <hr> Last edited on 2006-07-20 19:36:43 by <span title="ppp-71-139-187-151.dsl.snfc21.pacbell.net"><a href="StephenWeeks">StephenWeeks</a></span>. </body></html>
