Just wanted to mention that all my problems with building and missing gi module stemmed from improperly detected highest version of python. After I removed python 2.x and 3.9, the installation (build) finished without issues. My current version of python is 3.12. From what I can see the prepare() only checks for 3.11 and lower, that's why it found 3.9 in my system instead. Here's the log: https://pastebin.com/jUftCxGT I know nothing about python so can't really dig into this in any helpful manner. I'm here for the CNC :D

I used a yay/pacman -Qs python2 and got no further results. Started linuxcnc setup and got that yapps error.

If you removed python2 that would remove python2-yapps and then the old linuxcnc build

Started linuxcnc setup and got that yapps error.

Which 'that yapps error'

My impression is that you don't keep your system up-to-date anyway I don't have time or energy to provide tips on system maintainance; look into the forum for that

Hi Fabio,

thanks for the hint. I used a yay/pacman -Qs python2 and got no further results. Started linuxcnc setup and got that yapps error. Any hints how to find residuals?

Finally it seems, that there is a mismatch with python-2 packages and current linuxcnc libs. I uninstalled all of them and ended up in a "yapps" conflict.

This isn't using python2 since v2.9.1 update on 2023-10-30

If you had removed all the python2 packages and still had "yapps" conflict you hadn't removed all python2 packages

tclx packages are also tied to tcl version

Hi all,

in my hopeless situation I started to clean up and did crazy things. Finally it seems, that there is a mismatch with python-2 packages and current linuxcnc libs. I uninstalled all of them and ended up in a "yapps" conflict. Reinstalling that too did the trick. Everything installed nicely. TCL/TK is on its latest version 8.6.

Hope that helps others to find the error. Running the lcnc installation from scratch seems to make a clean python environment necessary.

and good luck Tweety

I am also not sure if tcl/tk version 8.6 is ok or if it should be 8.4.

Check on https://archlinux.org/packages/ (8.6), fully update you system before dealing with AUR pkgbuilds

Look into building in a clean chroot with for example paru --chroot for an easy way

Hi all,

I got stuck here

checking match between tk and Tkinter versions... Traceback (most recent call last):
  File "<string>", line 1, in <module>
ImportError: No module named _tkinter
Traceback (most recent call last):
  File "<string>", line 1, in <module>
ImportError: No module named _tkinter
TCL mismatch: 8.6 vs 
configure: error: Python requires use of Tcl  and Tk .
Install this version and specify --with-tclConfig and --with-tkConfig if necessary
==> ERROR: A failure occurred in prepare().
    Aborting...
 -> error making: linuxcnc-exit status 4
 -> Failed to install the following packages. Manual intervention is required:
linuxcnc - exit status 4

I checked here backwards and generally in the internet but didn't find a solution. I am also not sure if tcl/tk version 8.6 is ok or if it should be 8.4.

Anny advise? greez2all Tweety

@simona

Solved with:
yay -Rs mingw-w64-gcc libtirpc-compat netkit-rusers nfsshell

This would have been avoided building in clean chroot, both the hassle of the error and removing the packages

I think I understand that it's about creating an independent environment and installing there.

It don't install there, it build there

you install the builded package in your system

That kind of thing that takes up your disk space and somehow dirty up your installation. No thanks.

It creates a folder which you can deleted later and is not dirtying your installation, the chroot for building gnuclad (a small cli program) is 2GB pratically all of Arch packages

It create an isolated environment and build the package there, this is the way Arch Linux packages are build

Building in chroot prevent unwanted dynamic and other quirks of users system and I know your system have several

It is the reccomended way of building compilers on AUR

It is also helpful when you need to use conflicting makedepends like the nodejs versions and the only sane way to deal with stuff like ffmpeg AUR variants, mesa AUR variants etc

I prefer things that are simple and linear. A single package shouldn't complicate your life like that.

except packaging isn't always simple

The true question is: where when I install linuxcnc, yay take the include used? Where is stored the path?
locate rpc.h
find
/opt/watcom/h/nt/rpc.h
/usr/i686-w64-mingw32/include/rpc.h
/usr/include/capnp/rpc.h
/usr/include/event2/rpc.h
/usr/include/rpc/rpc.h
/usr/include/tirpc/rpc/rpc.h

Solved with:
yay -Rs mingw-w64-gcc libtirpc-compat netkit-rusers nfsshell
/usr/include/wine/windows/rpc.h
/usr/x86_64-w64-mingw32/include/rpc.h

I've been doing some research on this chroot installation. I think I understand that it's about creating an independent environment and installing there. That kind of thing that takes up your disk space and somehow dirty up your installation. No thanks. I prefer things that are simple and linear. A single package shouldn't complicate your life like that. thx for FailFast and SkipReview.
