[mpich-discuss] a question related to installation of MPICH2 with pgf90 and pgcc (PGI fortran and c compiler)

[Rui Mei]

I first set FC=/opt/pgi/linux86-64/10.4/bin/pgf90 and
CC=/opt/pgi/linux86-64/10.4/bin/pgcc and then run the configure command in
default. Do I need to add FC and CC as some option with configure command? I
thought defining them before executing configure should be fine.
