[petsc-users] Trouble configuring PETSc with serial MUMPS (no MPI)

[salvador]

Dear PETSc team,

I'm trying to compile PETSc with *MUMPS* in *serial mode* (without MPI), 
and I’ve encountered an issue during the |./configure| step.

Here is the command I'm using:

./configure \
   --with-cc=gcc \
   --with-cxx=g++ \
   --with-fc=gfortran \
   --with-mpi=0 \
   --with-scalar-type=complex \
   --with-petsc-arch=arch-linus-c-opt-complex \
   --with-blaslapack=1 \
   --with-mumps=1 \
   --with-scalapack=0

However, I get the following error:

*********************************************************************************************
            UNABLE to CONFIGURE with GIVEN OPTIONS (see configure.log 
for details):
---------------------------------------------------------------------------------------------
   Package mumps requested but dependency scalapack not requested.
   Perhaps you want --download-scalapack or 
--with-scalapack-dir=directory or
   --with-scalapack-lib=libraries and --with-scalapack-include=directory
*********************************************************************************************

My understanding is that *MUMPS can be used in serial* (according to its 
documentation), but PETSc seems to expect *ScaLAPACK* as a dependency 
even without MPI.

  *

    Is it possible to use MUMPS in PETSc *without MPI and without
    ScaLAPACK*?

  *

    If not, is there a way to enable serial MUMPS with PETSc?

Any guidance would be appreciated.

Best regards,
/Salvador
