I am unable to find out what I need to have installed to make the configure script find "libsoxr" because sox itself installed: ./configure --enable-avresample --enable-gpl --enable-libx264 --enable-nonfree --enable-libmp3lame --enable-libfaac --enable-frei0r --enable-libsoxr ERROR: libsoxr not found Could anyone give me a clue?
