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:</div><div><br></div><div><div style="margin: 0px; font-size: 14px; font-family: Menlo;"><div style="margin: 0px;">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.</div><div style="margin: 0px;"><br></div><div style="margin: 0px;">Attached please find the log files. </div><div style="margin: 0px;"><br></div><div style="margin: 0px;">I really appreciate your help!</div><div style="margin: 0px;"><br></div><div style="margin: 0px;">Best regards</div><div style="margin: 0px;"><br></div><div style="margin: 0px;">Yan</div><div style="margin: 0px;"></div></div></div></body></html>
