Re: [Discuss-gnuradio] Problem linking volk gnuradio3.7.4

Hi Marcus, I'm very sorry for having sent my message four times, but a
problem on my email client prevent me to see the sent messages, so I was
in doubt it was sent or not.
Anyway rm -r build & re-make.... solved the problem, now it's building
3.7.4...

many thanks, Stefano ik2yxt
