How to build linuxcnc on buildroot?

I need to build linuxcnc in buildroot, is there any reference document?

What is "buildroot" ?
-
If you mean building from sources (on github) :
linuxcnc.org/docs/html/code/building-linuxcnc.html

If you mean buildbot:
buildbot.linuxcnc.org/

I need to port Linuxcnc to an arm system, and then I need Buildroot to build and compile linuxcnc

My development board uses an RK3588 motherboard

There are ready made debs for ARMHF architecture here
buildbot.linuxcnc.org/dists/buster/maste...reempt/binary-armhf/
What architecture is RK3588 listed as?

The RK3588 is based on the ARMv8.2-A architecture and uses a 64-bit ARM (AArch64) core.

Building Linuxcnc on any hardware platforen is not difficult. I did a video of how to do it.


The  hard bit is to build  the PREEMPT_RT real time kernel as generally, there are no pre-built Debs for it. Using the 6.1.12 kernel and above will avoid the need to apply the RT patch to kernel source. This might help.

There's no information that I can recall for cross compiling Linuxcnc.

When compiling Linuxcnc for the RPi platform (4/400 or 5) I've either done it natively or via QEMU.

For those that are unaware Buildroot is a cross compiling system for building Linux file systems, generally aimed at embedded systems.
