Re: [Discuss-gnuradio] [VOLK][announcement] VOLK release impeding

[Barry Duggan]

Hi Ralph and others,

When I work on a project, I use the tools I have, along with the 
knowledge of how to use those tools. Over the past 50+ years of my 
career, I have done mostly real-time embedded software. Most of those 
projects required a cross-compiler to produce the object code. Since 
that was my work, I had the tools to get it done.

Now I am retired, programming for fun, and playing with gnuradio as part 
of my amateur radio hobby. I used to have a good Linux system, but it 
crashed, so what I have left is a Mac mini - yes, I plug an HDMI monitor 
and a USB keyboard into it ;) Looking back at the specs for the Linux 
system, the Raspberry Pi has more capability than it did: faster, more 
memory, etc. So why not use it?

I think we are getting off-topic here, except for the fact that GR 3.8 
*can* be built on an rPi 3B+. So let it run over night :)

Happy computing!
