Re: [Discuss-gnuradio] Building on ODroid C2 running CentOS 7 report.

[Marcus Müller]

I can really well understand the nature of "wanting to learn by doing"
:) but since GNU Radio builds excellently without GRC or graphical
(gr-qtgui, gr-wxgui, gr-sdl) interfaces, I'd really say: Start with GNU
Radio minus graphical stuff – adding that later on when necessity
dictates is probably a good idea, but for now, it sounds a bit
"overkilly", to be honest.

If you want to wrap things up for multiple different deployments (or
even just deployments at different times), going the extra mile of
cross-building a CentOS package definitely sounds like the skill I'd
prefer to have, rather than building on the device itself.
That way, installing GR boils down to a simple rpm command, rather than
a recompile just to get this stuff done on yet another machine. Also, if
there's already a gnuradio package SPEC that defines all the
dependencies, rpmbuild will take care of making sure everything
necessary to do the package build will be there – no manual chasing
dependency rabbits down dependency holes, and the resulting binary
package will automatically demand that you yum install the GNU Radio
dependencies. Notice that if your .edu, the electricity spent on
cross-compilation is probably paid for, whereas your hours chasing
dependencies might or might not be :D

Best regards,
Marcus
