</span>Context: this affects the auto-build MPI library only, not the use of<br>
an existing MPI library found on a cluster or even the one found on<br>
ubuntu, debian, OSX etc. As far as I can see there is thus no way of<br>
"manually" specifying extra libraries (in an option list)</blockquote><div><br></div><div>You can modify the global LIBS variable.</div><div><br></div><div>-erik</div><div> </div><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">since this<br>
only happens in exactly the case where the option list says "build<br>
yourself" or the auto-detection fails.<br>
<br>
Frank already gave the answer as to where to modify things (it<br>
literally is) in his email:<br>
<br>
$ENV{MPI_LIBS} .= " rt util" if($^O == "linux");<br>
<br>
and as said rt and util as part of libc6 anyway so they are always<br>
present.<br>
<br>
