Re: Illegal Instruction error ...

Hm, this looks like a problem when calling the FFTW library. Maybe you
use the double precision version of the library but gadget thinks it
calls the single precision one, or vice versa. Try to toggle the
DOUBLEPRECISION_FFTW compile time switch, or see whether setting
NOTYPEPREFIX_FFTW makes a difference.
