I think I have MUMPS successfully working with:<br /> * An older copy of the mumps bindings from: http://mathema.tician.de/dl/software/boost-numeric-bindings<br /> * This was coupled with the traits that I had had from a previous buiild: http://www.terborg.net/numeric_bindings_20090209.zip <br /> * And the latest bindings from the boost sandbox (which probably have no effect on this).<br /> * MUMPS compiled with Winmumps and bound to Intel MKL for blas, lapack, etc.<br /><br />The regression test in the mumps lib directory seems to work.  The only changes I made were in mumps_driver_4_8_0<br />* I changed the includes: #include &lt;smumps_c.h&gt; to #include &lt;mumps/smumps_c.h&gt;, etc.<br />* This probably makes sense in general since the mumps libraries are not likely to be installed in the root include.<br /><br />-Jesse
