I have an SBC that I only can install FreeBSD (probably OpenBSD, too), and from searching for some information I understand I just need Python3, and a “bit” of a preparation, and it should work.
Firstly, has anyone ever done it already? I would love to compare notes.
Secondly, at my first attempt, to me it seems the code uses linux headers (maybe just this one).

The SBC is a “Niuguy NIU-one”, intel based “mini” computer, I used it as my firewall, but upgraded the firewall, so it is just collecting dust, why not try to use it? It is still plenty powerful to run linux or freeBSD. The problem, is that there is some weird video hardware in it, and any linux distro just goes black screen at the beginning of the installation, even in text mode. I have been trying to install ubuntu for weeks, but didn’t get anywhere. So, I thought I’ll try to go down another road, installing klipper on freeBSD. But kiauh works only with linux (perhaps even only debian based distros). So, I am now trying to install klipper manually.
I am building a Voron2, and I am going to use a SmartPrintCoreH7x board (or two, since it only has 5 stepper drivers). I already have successfully set up klipper to run on the board, I just didn’t want to buy a RPi just to run clipper, when I have a perfectly good computer.
I tried adding linux_enable=“YES” to /etc/rc.conf, but it didn’t help. I have a feeling that would only help if I already had a linux binary (just guessing), but in my case, the c_helper.so module compilation just fails.
I dug out the compile command from klipper/klippy/chelper/init.py, and executed it, and got the same error.

Could chelper be changed, so that it wouldn’t contain any linux system call?
