hi, maybe i think i 've understod the problem.
in the program i'm trying to run there's a call for a routine "c05nbf" and if i comment it everything works when i compile and i don't get any error.
I'm at the first steps with fortran and i presume that these routines are the same as the libraries in C but i don't know where to get this specific routine.
what do you think?
thanks
