[petsc-users] Configure error after upgrading GCC

[Amneet Bhalla]

Hi Folks,

I upgraded GCC (GCC-5 to GCC-7) on Ubuntu following the first suggestion
given here:
https://gist.github.com/application2000/73fd6f4bf1be6600a2cf9f56315a2d91

I then removed system mpich (which was using GCC-5) and reinstalled it
using Ubuntu package manager. However, now I am getting the following
configure error with PETSc

===============================================================================

TESTING: CxxMPICheck from
config.packages.MPI(config/BuildSystem/config/packages/MPI.py:381)


*******************************************************************************

         UNABLE to CONFIGURE with GIVEN OPTIONS    (see configure.log for
details):

-------------------------------------------------------------------------------

C++ error! mpi.h could not be located at: []
*******************************************************************************



I am attaching the configure.log as well. Any hints on what I should be
doing?

Thanks,
