I think you misunderstand. The API differences are not between 32-bit and 64-bit; rather they're between FFTW2 and FFTW3
- The new (FFTW3) version of the script is verified as working in both 32-bit and 64-bit - I expect that the current (FFTW2) version would work in 64-bit, if we either found or compiled a 64-bit FFTW2 library. The basic interface is the same in both, so most people won't notice the difference. I'm new around here, so don't expect that my opinion ought to carry a lot of weight. In particular, I've no idea whatever how much code there is out there that relies on the existing (FFTW2) interface. But I'd suggest: - rename the existing fftw as fftw2 - call the upgraded version plain old fftw ... so that the default is to get the newer library (which works with the same basic interface as the older library); but any legacy code that relies on the existing interface can easily use fftw2 instead of fftw and avoid any further rewrite of their own code. (This might need some careful commenting or perhaps a better name for fftw2, as otherwise one might easily think that fftw2 was newer than fftw).
