The "pgiFortran" macro told the C compiler to use the Fortran-calling-C conventions of the PGI Fortran compiler. Those conventions *should* be the same as the ones of the ifort(1) compiler (at least they were). Did you call the Fortran function UTOPEN(3f) before you called the function UTDEC(3f)? > Thanks, > > Daniel.
