Successfully running LabVIEW on a RockPi S 512MB

I've managed to get the runtime happy enough to run on the RockPi S, a 64bit quad core SBC that's a third the size of a Pi. The LabVIEW stuff is still 32bit of course but this opens the door for supporting even more devices.

One of the tricks I pulled to get it to work is to first enable armhf (32bit packages) on the RockPi, manually edit the lvrt20-schroot package metadata to remove its dependencies on schroot and python since it was trying to install the 32 bit versions, and just manually install those packages before manually installing the edited lvrt20-schroot package. I also needed to install netbase for the labview service to start and I installed binutils to get the tools on the RockPi to unpack and repack the package.

I'm looking to automate this process but I'm not sure how to do all the architecture specifications from the commandline. If anyone has insight on easy ways to accomplish this I'd love to hear them so I can extrapolate this to other devices as well (looking at the Banana Pi M2 Zero next).

This assumes you've got the RockPi up and running and can access it already:

ssh/console/shell into device

>mkdir lvrt20-schroot
>cd lvrt20-schroot
>echo "deb [trusted=yes] http://feeds.labviewmakerhub.com/debian/ binary/" | sudo tee -a /etc/apt/sources.list
>sudo apt-get update
>apt-get download lvrt20-schroot:armhf
>sudo apt-get install schroot python avahi-daemon netbase binutils nano
>ar x lvrt20-schroot_20.0.0-4_armhf.deb
>tar xzf control.tar.gz
>nano control

Remove the schroot, python entries from the Depends: line
Ctrl+x to exit, Y to save, use same filename

>tar --ignore-failed-read -cvzf control.tar.gz {post,pre}{inst,rm} md5sums control
>ar rcs lvrt20-schroot.deb debian-binary control.tar.gz data.tar.gz
>sudo dpkg --add-architecture armhf
>sudo dpkg -i lvrt20-schroot.deb
