You have an issue while setting TCLLIBPATH. When the environment variable is empty prior to linuxcnc instalation your script sets the variable to ":/usr/lib/tcltk/linuxcnc" which produces an invalid result. Hence I suggest to change it to "/usr/lib/tcltk/linuxcnc:$TCLLIBPATH" which is safer since "/usr/lib/tcltk/linuxcnc:" would be valid.

Here it is the explanation: https://chatgpt.com/share/790d5a9c-cea7-47cb-a25d-3d76aea5d20a

While I've managed to figure out my previous issue (I was just missing the path in $PATH variable) I've encountered another issue. The python version changed so I wanted to rebuild the package linuxcnc. Unfortunately I get this error during building:

checking for python pango module... Traceback (most recent call last):
File "<string>", line 1, in <module>
ModuleNotFoundError: No module named 'gi'

From what i've googled i need to install PyGObject but pip refuses to install it and I can't find this package in the repo for python3. Any help will be greatly appreciated.

After one of the recent updates I started getting this error:

Debug file information:
Note: Using POSIX non-realtime
/usr/share/linuxcnc/hallib/axis_manualtoolchange.hal:1: execv(hal_manualtoolchange): No such file or directory

Any ideas how I can fix it? I've checked, the file is there:

-rwxr-xr-x 1 root root 2463 04-23 11:59 hal_manualtoolchange

simona can't reproduce, this already depends on libtirpc

$ LANG=C pacman -Qo /usr/include/tirpc/rpc/rpc.h
/usr/include/tirpc/rpc/rpc.h is owned by libtirpc 1.3.4-1

Nebulosa GPereira PR welcome here at the moment https://github.com/FabioLolix/PKGBUILD-AUR_fix (update coming)

InnerBushman I'm not notified about modiifed comments FYI

configure: error: Unable to use rpc.h

Hi. For some reason in /etc/profile.d/linuxcnc.sh the line is added as:

export TCLLIBPATH=/usr/lib/tcltk/linuxcnc:/usr/lib/tcltk/linuxcnc:/usr/lib/tcltk/linuxcnc:/usr/lib/tcltk/linuxcnc

Anyone have any idea what's causing it to get duplicated 4 times?

PS: @FabioLolix have you considered adding GPereira as co-maintainer yet?

Hello FabioLolix, can you add me as a co-maintainer? I am the initial submitter of this package and would like to continue involved in maintaining it.

Hi, I have the following message error
