I run into [ann] in Pd's website (http://puredata.info/Members/dmorelli/ann/ann/) from the Fann homepage and downloaded the Linux version, but it's a 32-bit build and Pd can't load it. I can't find it in deken. Anyone (IOhannes maybe, since you have provided the Linux build) has the source code so I can try to compile (any compilation instructions would be great too).
Thanks, Alexandros
