Jetson Nano as LinuxCNC driver

Thank you both for your replies. I saved the file as per the wget command line. When I tried sudo apt-get install it said it was selecting "linux-uspace:armhf" instead of "./linuxcnc-uspace_2.8.0~pre1.5968.g69df9c1ba_armhf.deb" and said "Some packages could not be installed. This may mean you have requested an impossible situation or if you are using the unstable distribution that some packages have not yet been created or been moved out of Incoming. The following information may help to resolve the situation: The following packages have unmet dependencies." It the lists about 50 dependencies of linux-uspace:armhf, just about each of which it states is not installable.
I can post the terminal o/p if that helps, but it's long.
On the other hand, if I were to compile it from source, I would appreciate any pointers as to how to start that process.
thx

You would need to satisfy the same dependencies to compile, so it might be useful to see the list.

Hi andypugh,
thanks for taking a look at this.

That is quite a list.

Do any of them exist in the package manager? Which Linux version are you running?

Well, and have you tried adding the foreign architecture to your installation? Armhf sould be compatible with aarch64.

From Linux headers 4.9 it looks like you are using a Stretch. Any chance to upgrade to Buster? (Multi-Arch has better support on Buster. [But Stretch is OK too.])

I ran a dpkg -s query and about half are not installed, see below. It is Unbuntu 18.04.3LTS
