Anyways, if you don't succeed in building with libDSP, you can still use the naive C implementation of the complex multiply-and-add function (see the README in libconvolve and the Makefile).. jack_/libconvolve themself should work perfectly fine with newer gcc's.. Flo P.S.: Maybe anybody has some ready to use optimized complex multiply-and-add function lying around? Let me know.. -- Palimm Palimm! http://tapas.affenbande.org
