Re: [Discuss-gnuradio] Cannot compile Volk

[Josh Blum]

The problem is that volk_16i_32fc_dot_prod_32fc_a_sse is using MMX
instructions which it seems that you cant do in 64 bit windows

These should probably be replaced with SSE equivalent functions
m0 = _mm_set_pi16(*(aPtr+3), *(aPtr+2), *(aPtr+1), *(aPtr+0));
m1 = _mm_set_pi16(*(aPtr+7), *(aPtr+6), *(aPtr+5), *(aPtr+4));
