Thanks, this is fascinating. I'll delve into it at some point. But for now, say I'm on Debian and I install the fftw package. Could the packager put a post install script to run the runtime tests and cache the results for the library to use so that apps which leverage fftw don't have to do the test on each instantiation? Edit: clarification
