f2py compile multiple files, Exception: Check the blocks #43

I am trying to compile three fortran 77 files with f2py. I know the files compile with ifort and gfortran.

f2py produces a long trail of warnings and ends with a message to "Check the blocks":

I have found one post from 2004 that addresses this error http://osdir.com/ml/python.f2py.user/2004-04/msg00000.html but it's not clear to me if this relevant for my case. I'd be grateful for any suggestions, thanks.

Could you show us the header and footer portion of the file roms_read_write.F?

Btw, f2py option -m requires specification of module name which is missing in your case. For example, try f2py -c -m foo --fcompiler=intelem *.F

I am having the same error. Even after aligning the do loops in the code, the error resurfaces. Does anyone have insights on this crackline error?
