Building machinekit-hal using buildroot

[Константин Сергеевич]

Hello

I'm trying to build machinekit-hal for BeagleBone Black with buildroot. I've already achieved succesful compilation, but still have some critical problems:

1. Install step fails, probably because wheel install does not recognize dest dir correctly. After the failure, target buildroot rootfs has host user directory created with some whl files in it (that supposed to be installed into /usr/lib/python3.11/site-packages).

2. PRU Drivers dont compile.

CMAKE_SYSTEM_PROCESSOR STREQUAL "arm"

returns false for some reason.

3. Xenomai 3 bindins are absent. I am building on top of 4.19 xenomai image, so I can use both realtime and Qt with graphic acceleration via PowerVR, but machinekit-hal supposedly supports only 2nd version of Xenomai. 

Does anybody tried porting machinekit-hal to xeno3 or building machinekit with buildroot or even cross-compiling to ARM? Advices and help are welcome!

Regards
