Hello everyone,
I'm trying to run LinuxCNC on BeagleBone Black which has Debian Stretch
installed, but it seems that LinuxCNC repo doesn't have armhf package for
Stretch. Is there any chance that I can build one myself? As I can run

I'm curious. Do you actually use physical machines to do the builds? I
assumed everyone ran VMWare's vSphere and had a ton of virtual machines

The x86 and amd64 builds all happen on a bunch of VMs (running
So using KEMU for the arm64 builds is either not working or to slow?
I'm interested because I'm setting up a virtual server farm too. but just
in planning stages now

I tried using qemu emulation, and it was way too slow. Running on a

The big advantage of the TX1 is the powerful Nvidia GPU that can be used

May be a Raspberry Pi could be used as a build machine for Stretch, armhf,
as Raspbian based on Debian Stretch is just released. I've successfully
built LinuxCNC on an RPi 3B running on Raspbian Stretch and run it on a BBB
running on Debian Stretch.
Interestingly, RPi has 64bit ARM CPU while Raspbi
