I'm trying to compile Aliki and I'm coming across this error: impdata.cc:264: error: 'SFC_WAVEX_GET_AMBISONIC' was not declared in this scope impdata.cc:264: error: 'SF_AMBISONIC_B_FORMAT' was not declared in this scope I see a sndfile.h reference on the web mentions a declaration which is close (for instance) SFC_SET_AMBISONIC - Modify a WAVEX header for Ambisonic format but not exactly correct. To go further, my particular sndfile.h has neither listed. Versioning issues? Any help much appreciated. brad media-libs/libsndfile-1.0.17-r1 -- Brad Fuller www.bradfuller.com
