@chetanpm

Did you try this solution:

export TCLLIBPATH=/usr/lib/tcltk/linuxcnc

https://aur.archlinux.org/packages/linuxcnc#comment-914603 I'm getting the same error when starting axis. I tried with 2.10 pre aur package too with the same error. I tried on linux-rt-lts 6.1 as well as mainline kernel 6.4 Does anybody know the solution to make it run?

Please change depend python2-imaging to its drop-in continuation fork python2-pillow.

Imaging is dead since 2009.

@Tweety

I just built this myself with no issues.

However, I don't see this having anything to do with the real-time kernel. I've seen these kind of errors popup due to weird ordering in the linking step. Unfortunately, the link ordering does matter.

Without being able to replicate the error, this is hard to track down. But, we can see that this is an error building milltask. In src/emc/task/Submakefile, try switching the order of the link step:

- $(CXX) -o $@ $^ $(LDFLAGS) $(BOOST_PYTHON_LIBS) -l$(LIBPYTHON)
+ $(CXX) -o $@ $^ $(LDFLAGS) -l$(LIBPYTHON) $(BOOST_PYTHON_LIBS)

Hi jkercher,

thanks for your reply.

I did a yay -Syu and tons of time went by since then. Result is a running 2.8.4.

As for khvalera I added the export line into /usr/bin/linuxcnc and everything is ok now.

... how dare you not having arch installed ...

@khvalera There is a file in the repo that is supposed to get put into /etc/profile.d that doesn't appear to work. Unfortunately, I don't have an Arch Linux installation running to investigate why that is. There is an environment variable you need to set. For now, I would recommend just adding this to ~/.profile:

export TCLLIBPATH=/usr/lib/tcltk/linuxcnc

@tweety Is that the only linker error you are getting? It got to the linking step which would imply that you have boost python dependency installed. If that is the only error, either your package needs to be updated or something recently got deprecated. If there are actually a whole slew of errors like this, then make never found the library in the first place. In that case, you may need to go hunt down the libboost-python*.so library and add that to the Makefile manually.

Hi there,

tried to get it running with linux-6.2.0.3.realtime1-4-rt Kernel. But it stops during make with that message. No clue how to handle that error. Any hints?

On startup I get the following error:

@InnerBushman It looks like that issue is resolved on the 2.9 release. Your hack works for 2.8.x branches. Unfortunately, I currently do not have an Arch based system up so I cannot make that change. I will when I get my system back up.

The component for 6-axis wireless USB pendant is not being compiled:

gcc version 12.2.1 too old: skipping hal/user_comps/xhc-whb04b-6

The reason is GCC version is incorrectly checked with sort, which puts 12.x before 4.7 which is the minimal version. https://github.com/LinuxCNC/linuxcnc/blob/2.8/src/hal/user_comps/xhc-whb04b-6/Submakefile

I added this in line 49 of PKGBUILD to trick it to not skip it. Basically lied to it it needs version 10.

sed -i "2s|4.7|10.0|" hal/user_comps/xhc-whb04b-6/Submakefile

It's a dirty workaround before it gets fixed properly by someone more competent than me.

I also reported an issue on LinuxCNC github issue tracker: https://github.com/LinuxCNC/linuxcnc/issues/2364
