--- Comment #2 from Benyahia.N <benyahia-nezha at hotmail dot fr> --- Salam Dominique d'Humieres Thanks for your response, that's so kind of you,fortunately, i have solved this problem only by using the command 'gfortran band-3c.for' unstead of 'gcc' command which must be used only with the 'c' programs. That was so obvious but it is things that can happen to everybody.
