Error regarding compiler conflict in mpich installation with fortran support

Error:

The selected Fortran 90 compiler /usr/bin/gfortran does not work with the selected Fortran 77 compiler ....

This happens when you have both fort77 and gfortran installed on your machine. As a solution, use variables F77 and F90 both pointing to the gfortran. The configure command should look like;

$./configure --prefix=<install-dir> --enable-f77 FC=/usr/bin/gfortran    F77=/usr/bin/gfortran

Installing fortran compilers

to install gfortran:

$ sudo apt-get install gfortran


to install f77

$ sudo apt-get install fort77
