Dear mpich staff,<br>
<p>
when I'm installing mpich-3.3.1 using gcc-8.3.1,
</p>
<p>
unset F90 export F90=gfortran export F77=gfortran
</p>
<p>
./configure --prefix=/home/majun2/dat01/setup_new/mpich/
</p>
<p>
<br>
</p>
<strong>error shows:</strong><br>
nfigure: WARNING: installation or configuration problem: Fortran 90 compiler cannot create executables.<br>
checking whether Fortran 90 compiler works with Fortran 77 compiler... configure: WARNING: See config.log for the failed test program and its output.<br>
no<br>
configure: error: <strong>The selected Fortran 90 compiler gfortran does not work with the selected Fortran 77 compiler gfortran.</strong> Use the environment variables FC and F77 respectively to select compatible Fortran compilers. The check here tests to see if a main program compiled with the Fortran 90 compiler can link with a subroutine compiled with the Fortran 77 compiler.<br>
