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

[Marcus Müller]

Dear Owen,

I'd say the fact that you quickly eat up all your RAM is the best
indication for it possibly being a good idea to cross-build for the
Odroid on a PC. I've never actually did a cross-compilation for CentOS
or Fedora packages (just for the same architecture), but that might just
be the way to go: Get a .spec file for GNU Radio on x86_64, adjust it as
necessary, and use it to build stuff for the C2. As said, I've never
done this myself, though.

Best regards,
Marcus
