[mpich-discuss] Problem with Intel Fortran Compiler and MPICH2 on Mac OS X

[Omer Acikgoz]

I have a problem using Intel Fortran Compiler 11.1 with MPICH2 version 1.3 on Mac OS X.

I do not have Intel C/C++ compiler, therefore when I compiled MPICH2, the C libraries were compiled using GCC 4.6 and I used ifort as the default fortran compiler. The compilation had no errors or problems, however, when I compiled my first code using mpif90, this is what I got

Undefined symbols:

When I change the default Fortran compiler to GNU gfortran, the code compiles with no problems. I suspect this is related to an incompatibility between GCC and Intel Fortran Compiler. What do you think?

Thanks a lot!
