[mpich-discuss] No Fortran 90 compiler

[Dmitri Chubarov]

Hello,

You have to install gfortran or any other Fortran-90 compiler or use mpif77
with your FORTRAN-77 codes.

Here is what configure says:

checking whether the Fortran 77 compiler (g77  ) works... yes

You have got g77, good, but g77 is old and most of the work on the GNU
Fortran compiler is on gfortran.
<...>

checking for f95... no
> checking for f90... no

> checking for pgf90... no
> checking for ifc... no
> checking for efc... no
> configure: warning: no acceptable Fortran 90 compiler found in $PATH

You do not seem to have a Fortran 90 compiler available on your system.
