Cannot compile opus on Mac osx 10.13.6

Hi, I am trying to complile opus on High Sierra, but I'm getting following error: /Users/admin/opus-1.5.1/silk/x86/VQ_WMat_EC_sse4_1.c:88:26: error: passing 'int' to parameter of incompatible type '__m128i' (vector of 2 'long long' values) v_cb_row_31_Q7 = OP_CVTEPI8_EPI32_M32( &cb_row_Q7[ 1 ] );

Any thoughts? Thanks
