<p class="xmsonormal"><span style="font-family:Consolas">The issue seems to be that MPICH (or libtool?) assumes that flags that clang accepts will be accepted by the Fortran compiler as well. But NAG doesn't accept '-dynamiclib' as an option. (I am asking NAG
about this as well.)</span><o:p></o:p></p>
<p class="xmsonormal"><span style="font-family:Consolas"> </span><o:p></o:p></p>
