[petsc-users] What is "You must specify a path for MPI with --with-mpi-dir=<directory>"

[Nan Zhang]

Hi there,

I am trying to install petsc with its own mpicc. I download it and untar it
under my directory. I export PETSC_DIR=`pwd` and export PETSC_ARCH=x86_64.

When I do configure:
./config/configure.py –with-shared-libraries=1 –with-x=0 –with-mpi=1
-download-hypre=1 –download-f-blas-lapack=1 –download-mpich=1
-download-mpicc=1 –download-f2cblaslapack=1

I got an error report:
+++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++
The version of PETSc you are using is out-of-date, we recommend updating to
the new release
 Available Version: 3.5.2   Installed Version: 3.4.2

             Configuring PETSc to compile on your system
===============================================================================
TESTING: check from
config.libraries(config/BuildSystem/config/libraries.py:145)

 *******************************************************************************
         UNABLE to CONFIGURE with GIVEN OPTIONS    (see configure.log for
details):
-------------------------------------------------------------------------------
You must specify a path for MPI with --with-mpi-dir=<directory>
If you do not want MPI, then give --with-mpi=0
You might also consider using --download-mpi instead
*******************************************************************************
How to solve this? I also attach my configure.log below.

Thanks!
Nan
