Before you go scorched earth on your externalpackages, did you turn on any packages? Some require<div>MPI and if they are already built when you switch to MPIUNI we could have forgotten a check. I would</div><div>leave off all packages to start. Then we can locate this error.</div>

I&#39;m trying to build a non MPI code and get this error:<br>
<br>
Undefined symbols:<br>
  &quot;_ompi_mpi_comm_self&quot;, referenced from:<br>
      _ompi_mpi_comm_self$non_lazy_ptr in libamrelliptic2d.Darwin.g++-4.gfortran.DEBUG.OPT.PETSC.a(PetscLinearSolver.o)<br>
     (maybe you meant: _ompi_mpi_comm_self$non_lazy_ptr)<br>
<br>
<br>
In the past I have linked libmpiuni.a but that did not seem to get created.  Did libmpiuni.a go away or did my make fail ...<br>
