Re: [Discuss-gnuradio] Cannot compile Volk

[Josh Blum]

Alright, i have kind of a fix. Here is the diff:
http://pastebin.com/fv4tRfEF

Basically, it looks like you cant MMX on win64. So I added mmx as an
optional parameter to the 3 machine definitions that get used on
windows. When on MSVC 64bit, the mmx arch will get overruled.

On the kernel side, I added LV_HAVE_MMX to the dot prod kernel. Since
this kernel requires MMX, in this case the build system will prevent its
building when MMX is not available (aka mmx is overruled):
