Problems building machinekit-cnc from source

[Michael Labuda]

Hello,

I am setting up a development environment and trying to build machine-kit from source, I was able to build machinekit-hal without any problems, but machinekit-cnc is a different story. Following instructions given on https://www.machinekit.io/docs/developing/machinekit-developing/#get-source-and-build I encountered problems immediately as there is no build_with_cnc script included in the machinekit git. I found this script in someone else's repo and copied it over. It started to compile but then failed after it couldn't find /machinekit-cnc/src/libnml/nml/inifile.XX. These appear to be symlinks to some fakeinclude directory. I put in some dummy empty inifile.XX files which got me a bit further but other source files are actually attempting to use an Inifile class that doesn't exist. What's going on here? Did I clone the wrong repo or something?

Thanks,

Michael

Yeah, the building of Machinekit-CNC is currently broken with work on supporting the EMCApplication work from Zultron. You can read more about it in https://github.com/machinekit/machinekit-hal/issues/267 . I am currently working on it but is it going slower that I would have liked. I am also changing the workflow of the building to be simpler and saner (actually read: So I like it better), so it is pretty unstable at the moment. The Machinekit-CNC will need to be updated to the same style as EMCApplication to actually function.

No, you cloned the right one. Probably. Checkout the e81023b8b9ae49a9e971d9da6d424297061772bc to use the scripts/build_with_cnc script.

I checked out that commit id and it built fine. Thanks for your help.

I also encountered  the same problem 。I‘ll try this check out later。

You just solved this problem by check out commit id？

Yes, the Machinekit-CNC@master cannot be currently built on top of Machinekit-HAL@master. This was done because the original build flow was extremely inflexible and the precedence was given to option to build Enhanced Machine Controller (which is developed as part of LinuxCNC and the development is much more active than Machinekit's own CNC portions). This is now possible - https://github.com/machinekit/emcapplication and can be previewed by following instructions here: https://github.com/machinekit/EMCApplication/issues/1#issue-666660311 .

I am hoping that Machinekit-CNC will be again buildable on Machinekit-HAL after CMake build system switch, which should filter out problems stemming out from kernel-space module past and streamline the whole operation.

Hi， Michael 

   I followed your advice to use the commit id  e81023b8b9ae49a9e971d9da6d424297061772bc  and use the  ./script/build_with_cnc 

   but I forgotted that I was running on a ARM64 board，there are many problems occured。

   Is there a available version on arm64 architecture ？

Hi,
the latest Machinekit-HAL should run on arm64 architecture - there is even testing of this: https://travis-ci.com/github/machinekit/machinekit-hal/jobs/371433497 (example of the latest push). I am not completely sure about the commit e81023b8b9ae49a9e971d9da6d424297061772bc, what kind of issue are you experiencing?

Cern.

Hi，

         When I install machinekit-hal with commit id  e81023b8b9ae49a9e971d9da6d424297061772bc  ，there is an error that “ rtapi/rtapi_io.h:39:43: fatal error: sys/io.h: No such file or directory”。

         If I install the latest version of machinekit-hal，it will be ok。but after that when I install machinekit-cnc，another error occurred named “

couldn't find /machinekit-cnc/src/libnml/nml/inifile.XX. ” 

Thanks

Wade

Hi all, long time no see!

i'm trying to build EMCapplication for an arm64 platform (Xilinx Zynq Ultrascale), alas things are changed quite a bit from last time i managed to make it work on a Zynq7000 some years ago!   

i think i managed to have machinekit-hal up and running, tests are a go, and i can halrun some examples with halscope and basic functionalities.

Trying setting up EMCapplication following this receipe:

https://github.com/machinekit/EMCApplication/issues/1#issue-666660311

seems to complete without complains, but when i run linuxcnc i get this:

LINUXCNC - 2.9.0~pre0

Machine configuration directory is '/home/zus/linuxcnc/configs/sim.axis'

Machine configuration file is 'axis_mm.ini'

Shutting down and cleaning up LinuxCNC...

LinuxCNC terminated with an error.  You can find more information in the log:...

googling around it could be related to a python2/python3 erroneous configuration.

zus@zus-cl:/usr/bin$ ls -l /usr/bin/python

lrwxrwxrwx 1 root root 9 Jan 24  2017 /usr/bin/python -> python2.7

should it be python3? 

sorry for the generic nonsense question, but i couldn't follow the recent developments of the project and in general i know very little 

about (modern) programming :-) 

Is there any suggestion on how to kickstart this? or any suggestion on how to check if i'm working in a 'sane' envoronment?

Hi Claudio

Im currently involved in creating a new Mksocfpga port for the Myirtech FZ3,

and updating the former ultra96 v1/v2 mksocfpga residents:

So I would very much know the name and brand of the board you are currently working on ?
Best wishes
