[petsc-users] PETSc config error

[Barry Smith]

  These installation questions should be sent to petsc-maint at mcs.anl.gov not to petsc-users.

   It appears there is something wrong/incomplete with the mpicc that your are using; it is not properly connecting the executable to the MPI shared libraries that it is needs which it should do automatically.

   Where did you get this MPI? Do /home/amrit/MPI/bin/mpicc -show and send us the results. Please send all future correspondence on this issue to petsc-maint at mcs.anl.gov
