From what I can see fftw 3.2.x is needed (which is only alpha) for 64-bit planner support: http://www.fftw.org/release-notes.html /FredrikOctave can be built without fftw, with the included fftpack. It'll be slower, but should work with 64-bit.. D. FFLAGS = -fdefault-integer-8 work. Otherwise, will --enable-64 break all fft functions when Octave is build with fftw support? /Fredrik |
