--- Comment #7 from Dominique d'Humieres <dominiq at lps dot ens.fr> --- > I "make distclean",and make again. Everything goes well. And gfortran is made. > The problem is solved. thanks for the advice. You're welcome! Further advice, 4.8.0 is quite old and unsupported: you should go to at least 4.9.3 or better 5.2. Your gmp, mpfr and mpc libs are also old. I am using GMP version 6.0.0, MPFR version 3.1.2, MPC version 1.0.3.
