Arch Linux User Repository

Hi jkercher

... you are my [code]-tag hero :)

Using the export within .bashrc is ok, allthough I modified the linuxcnc bin in the meantime to avoid systemwide path modifications. I guess that will be replaced when updating, but at the moment I am not able to build the package anymore. Didn't find the reason nor meaningfull error messages. Main difference is compiling the source with linux-rt. First build was with standard linux kernel.

Is it not possible to check whether TCLLIBPATH is empty or not and put the ':' accordingly as a separator?

@Tweety, code blocks are done with backticks. 3 for a block, 1 for inline:

`

This may work, but it will only work in the current shell. You will need to add this to something like your .bashrc:

export TCLLIBPATH=/usr/lib/tcltk/linuxcnc

I don't know what the AUR policy is toward modifying the users environment like that in PKGBUILD. I just added python2-gobject as a dependency.

Hi all,

I was not able to run linuxcnc using a config-file (templates/self generated). For linuxcnc the error message was: "can't find package Linuxcnc while executing "package require Linuxcnc ... check_config.tcl" line 141)" I found a solution after hours, mentioned here: https://forum.linuxcnc.org/9-installing-linuxcnc/42143-solved-linuxcnc-on-arch

leading to change of Line 35 in PKGBUILD, prepare() section to echo "export TCLLIBPATH=/usr/lib/tcltk/linuxcnc" > ${pkgname}.sh Using the original syntax leads to:

# echo $TCLLIBPATH
:/usr/lib/tcltk/linuxcnc

Where the ":" is the error source. In case the TCLLIBPATH was not set by any other process before it stays empty. Therefor it should be checked before the echo-statement to avoid a misplaced : . Just found this issue and solution, but don't know how to apply the change after installation now.

Second issue is the use of stepconf wizard. I had to install the additional package python2-gobject before stepconf showed up. pacman -S python2-gobject

Dependency should be included.

Last one is about using Linuxcnc in LXQT Desktop. Unfortunately the menus are not nicely build in comparison to the official Debian build. Stepconf, docs and icons are not available. But that's a minor issue.

... and what the hack is the correct "code" tags here ?

Now, you can use it for whatever reason you installed it for.

Yes, installed!! Version: python-setuptools 1:57.4.0-2

What to do now?

@williamrm.ti Do you have python-setuptools installed? To check:

pacman -Q python-setuptools

Error to compile LINUXCNC. Help-me please.

Good day!

Since 2.12.2020 is the new 2.81 ( http://linuxcnc.org/downloads/ ) ready. Can you say when they will offer it for update ?

Sincerely

Would you mind extending the description of the various linuxcnc packages to include whether they are for use with a realtime kernel or with uspace?

EDIT: I can confirm that installing boost-python2 allows LinuxCNC to build successfully.

@tellmi Installing https://aur.archlinux.org/packages/boost-python2/ fixed it for me @ragouel python2-boost seems to be a dependency
