Hello dear friends, I am sorry, I do not know how to program in C++, I was looking for something in "plain C", not C++. I seems that as Otto stated, complex.h is a C99 thing and OpenBSD does not fully support C99.
Anyway, I understand it better now. I will see whether I am able to modify the program and let it run under OpenBSD. Also, I have tested the fortran version and compiles perfectly, so I can work with it. Thank you very much. Ramiro. EA1ABZ.
