Many thanks to your quick response. It still doesn’t work.  

I used this configure line

./configure --prefix=/users/ybai5/mpich2-install F77=$ABSOFT/bin/af90\

           FC=$ABSOFT/bin/af90  --with-pm=mpd

and got this error:

configure: error: The selected Fortran 90 compiler /Applications/Absoft11.5/bin/af90 does not work with the selected Fortran 77 compiler /Applications/Absoft11.5/bin/af90.  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.

It’s so weird. If you need, I can send the log files. 

Thanks a million!

Best

Try setting both FC and F77 to af90.

Hello

I was trying to install mpich-3.1 but stopped at the first step: configuration. The Fortran compiler I have is absoft. I tried both the configuration command given by Readme file of mpich-3.1 and the configuration line given by Absoft. Both have the following error message:

configure: error: The selected Fortran 90 compiler /Applications/Absoft11.5/bin/af90 does not work with the selected Fortran 77 compiler /Applications/Absoft11.5/bin/af77.  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.

Attached please find the log files.

I really appreciate your help!

Best regards
