Dear all, I am trying to test PWscf on NEC machine, using MathKeisan library. But in the make.sys, which was generated by "configure.old sxcross", it stated that the fft library of Mathkeisan (version <= 1.4, zzfft3d) is buggy.
I searched the forum for a while but there is not updated information about this issue. Does anyone know whether this fft bug has been fixed? Otherwise I would use jmfft. Many thanks in advance! Best regards, William
