Save the attached file to the root directory of the 3.0 distribution (the one containing PH/) and use command "patch -p0 < phonon.diff". This should produce a patched version of PH/phonon.f90 that fixes the problem with example06. I don't know about the second case, but I think that the 2.1.5 version has the same problem (but needs a different fix) Paolo -- Paolo Giannozzi e-mail: giannozz at nest.sns.it Scuola Normale Superiore Phone: +39/050-509876, Fax:-563513 Piazza dei Cavalieri 7 I-56126 Pisa, Italy -------------- next part -------------- A non-text attachment was scrubbed...
