problem about linking a mixed c/fortran parallel code with mpif77

Hi,
I have a problem linking a mixed c/fortran code with mpif77:

the option for compilers and the error message are following :

The bold italic characters with a underline is error message.

(I run the programmes in clusters with linux centos 6.0, the compiler is parallel_studio_xe_2013_update1_intel64 and the mpi ismpich2-1.5 )

Thanks for any help.

I don't see why -nofor-main is not taking effect. mpif77, if correctly built for mpich2, would have embedded in it the -L and -l specifications for mpich2, so it appears there may be a conflict. Likewise, mpif77 and mpicc would have embedded -I specification for the mpich2 so you wouldn't need a consistent MPI include directory in ./MPI when you use them in place of ifort and icc. If you are building an open source application such as Openfoam, the wiki pages and help site for that application would be a better source of knowledge than this one, particularly as you aren't using an Intel provided MPI.
