[petsc-users] [petsc-maint #97642] Configuration with Intel compilers

[Satish Balay]

1. hypre requires a c++ compiler
2. --with-mpi-dir=/curc/tools/free/redhat_5_x86_64/openmpi-1.4.3_intel-12.0_ib --with-cc=icc --with-fc=ifort

Its best to use mpicc/mpif90/mpicxx from the mpi install - and not
change compilers for mpi.

So use only
'--with-mpi-dir=/curc/tools/free/redhat_5_x86_64/openmpi-1.4.3_intel-12.0_ib'
[so that PETSc automatically uses mpicc from the specified mpi-dir] - or use:

--with-cc=/curc/tools/free/redhat_5_x86_64/openmpi-1.4.3_intel-12.0_ib/bin/mpicc
--with-fc=/curc/tools/free/redhat_5_x86_64/openmpi-1.4.3_intel-12.0_ib/bin/mpif90
--with-cxx=/curc/tools/free/redhat_5_x86_64/openmpi-1.4.3_intel-12.0_ib/bin/mpicxx
