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

line 28 PKGBUILD change to

      
echo "export TCLLIBPATH="$TCLLIBPATH  /usr/lib/tcltk/linuxcnc"" > ${pkgname}.sh

colons: perceived by TCL as part of the path, apparently from the inheritance of Windows paths like C:/Tcl/lib https://wiki.tcl-lang.org/page/TCLLIBPATH

Here an updated PKGBUILD according comments below, right version of libgpiod, rewrited function package (delete duplicate commands), right version of licences etc:

https://0x0.st/HRkB.txt

Note: linuxcnc.sh not needed, you should do export TCLLIBPATH=/usr/lib/tcltk/linuxcnc or reboot before first launch linuxcnc

Colleagues suggest a solution, current as of 2023-02-25 -. https://archlinux.org.ru/forum/post/260540/

error, typo in the file PKGBUILD.

should be /usr/lib/tcltk/linuxcnc if :/usr/lib/tcltk/linuxcnc then :/usr/lib/tcltk/linuxcnc then

it seems to be a bug in the package builder that they added colons and when TCLLIBPATH is empty it substitutes them.

line28

echo "export TCLLIBPATH=$TCLLIBPATH:/usr/lib/tcltk/linuxcnc" > ${pkgname}.sh

try running an already built package like this

export TCLLIBPATH=/usr/lib/tcltk/linuxcnc

linuxcnc

if it helps, you can rebuild with the fixes

PKGBUILD line 28

change to

echo "export TCLLIBPATH=/usr/lib/tcltk/linuxcnc" > ${pkgname}.sh

@ivanovp test with libgpiod downgrade to 1.6.4.2

I tried to compile it, I got an error: https://pastebin.com/J9acSDzq

In file included from hal/drivers/hal_gpio.c:39: hal/drivers/hal_gpio.c:188:50: error: invalid application of ‘sizeof’ to incomplete type ‘struct gpiod_line_bulk’ 188 | (ptr)[c].bulk = rtapi_kmalloc(sizeof((*ptr)[c].bulk), RTAPI_GFP_KERNEL);

Hi jkercher,

just after reinstalling I ran into a dependency problem at linuxcnc startup regarding OpenGL.

Installing python-openglpackage solved it for me. Should that be in the dependency check too?
