Re: [Discuss-gnuradio] Volk development using orc

[Gerald Baier]

D'oh! Thanks that did the trick. For everyone who is interested, this is 
the snippet of working code:

gr_complex *out = (gr_complex *) output_items[0];
int noi = noutput_items;
gr_complex temp1[noi];
gr_complex temp2[noi];
// do something with temp1 and temp2
volk_32f_x2_add_32f_a((float *)out, (float *)temp1, (float *)temp2, 2*noi);

Best regards,

Gerald
