Hello Greg, would you mind giving https://github.com/gnuradio/volk/pull/813 a try on your machine, please? Hello Johannes, sadly I could not find a way that both introduces no random new includes in volk_common.h that causes functional changes in consumers of the header, while still addressing the issue Greg describes; the cleanest seems to be moving the mostly-internal math functions out of volk_common.h to a new header. That of course means API breakage; sorry.
