You can build from source on the Beagle. I have done it.

Great!

 

However, the
Beagle has only a single core processor, you will have to mount swap
space, the 4G of memory isn't roomy - at all, and you will have to
install a bunch of additional packages. 

Can you point me to those packages so that I do not miss something? I installed pre-reqs for GNU Radio and cmake seems to run fine with some warnings/messages as shown in my first email.

 

I don't recommend native builds but it can be done. Cross develop if
you can. I seem to recall it took a few /days/ to build, multiply if
there is a failure. You should also mount an external USB disk for
swap, /tmp, etc. 
 

The compiler on the Beagle is old. I installed a more modern version.

I tried to cross develop but was not able to do so. I am still working on that approach. If you have done it or have any pointers please do share.  What compiler did you use? Did you do a full install of GNU Radio on BBB? 

The Beagle isn't suited for GNURadio unless you have a low data rate
and low memory requirements, but it can work.

I'll also use low data-rates :)

 

Regarding VOLK, you may have to tune the build. You will have to look
up the processor specifics and tune the build appropriately.

I'll look how can I do it. Thanks for your time.
