This is strange. libmpifort is a different version than libmpicxx.so ?<br>
<br>
If specifying these additional options (manually) get a functional superlu_dist build - you can also specify them to petsc configure via<br>
<br>
--download-superlu_dist-cmake-arguments=string<br>
<br>
[but yeah - good to know if this issue persists with petsc/main]<br>
