[mpich-discuss] Fwd: compiling parallel programms with ifort

[mohamed ali]

Hi Anthony
it gave me this message:
The Open MPI wrapper compiler was unable to find the specified compiler
gfortran in your PATH.

Note that this compiler was either specified at configure time or in
one of several possible environment variables.

can i change any variable of mpif90 to appoint to ifort rather than
gfortran?
