  For simple stuff, you would probably find it faster to actually do the
building ON the BBB, using the ARM native GCC.

Dennis,

I’m afraid I’m taking this a bit off topic, but part of your answer tantalized me:

…I also should see about setting up Buster (Debian 10) in VirtualBox first; I do have Stretch in VirtualBox already…

I’m pretty sure you don’t mean what I hope you mean, but do you have a Beaglebone VM environment set up? Or are you just referring to having the current version of x86/64/standard desktop Debian VM running under Virtualbox?

I know there have been efforts in the past to emulate the old beagleboard devices under qemu but I would be thrilled to be able to run a modern emulated am335x in any desktop environment. I looked into bringing that back up to date but it was about 3 steps outside of the actual tasks I need to work on and simply not worthwhile to do so.

Back on topic, as to Megha’s question, there are some details about cross-compiling here which have been useful to me in the past, though now to ensure all the pieces end up in the correct places I have stayed with compiling directly on the machine.

  No -- just the Intel compatible OS.

  And I'm afraid Molloy 2nd Ed may already be dated -- I'm not finding
the cross-build toolchain in Debian Stretch. No idea if the section on
setting up QEMU is still valid either.

wulfraed@stretch:~$ apt-cache search cross-build-essential
wulfraed@stretch:~$ apt-cache search crossbuild-essential
wulfraed@stretch:~$ apt-cache search armhf
wulfraed@stretch:~$

  Mea culpa...

  Appears, since I'd installed Stretch from DVDs, it had never looked at
the online "main" repository. Just added that to the source list and after
an apt-get update the cross build stuff is showing up in a search.

  So I am proceeding on the basis that Molloy 2nd Ed IS VALID.
