@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

Bwidget package has permissions issues, had to add.. chmod -R 755 "${pkgdir}"/usr/lib/tcl8.6/* to PKGBUILD

Even though I can see that Bwidget is clearly installed on my pc, it can't find it?

configure: error: BWidget not found! install with "sudo apt-get install bwidget"

Any ideas?

Please update to 2.8.4

Also TCLLIBPATH is still a thing

Hi everyone. Today, during the compilation it complained about missing libffi.so.7. Current version is 8. After manually installing version 7 of this lib the compilation continued until it failed on 'boost'. I've noticed i have two versions of boost installed. After removing the older one, the new one was rebuilt and the compilation finished.

The file /etc/profile.d/linuxcnc.sh contains ':' character that breaks the path for me. After removing it, everything works fine.

Cheers, Bushman

@nmanarch That is the exact problem that the linuxcnc.sh script is supposed to fix. All it does is set an environment variable. See if setting that variable manually fixes your problem: export TCLLIBPATH=/usr/lib/tcltk/linuxcnc. If that works, then the linuxcnc.sh didn't wind up in /etc/profile.d as it should have.

@laserk3000 Applied your change, thank you!

Hi all. Many thanks to Laserk3000 for this trick that correct the end of the process for build/install

-Dm 644 "${srcdir}/${pkgname}-${pkgver}/src/linuxcnc.sh" -t "${pkgdir}/etc/profile.d/"

Thanks for maintaining the package.

But i have an error when starting linuxcnc:

can't find package Linuxcnc while executing "package require Linuxcnc " (file "/usr/share/linuxcnc/hallib/check_config.tcl" line 141) check_config validation failed LinuxCNC terminated with an error.

I have found this thread on linuxcnc saying blt-2.5 require .. i have test the package blt 2.4z-12 package of arch but nothing change / work..

https://forum.linuxcnc.org/51-ot-posts/39134-compiling-linuxcnc-on-slackware-some-warnings?start=10

Someone have solve this ? many thanks. have a nice day.

Turned out I had libtirpc-compat installed. Removing it fixed the problem.

There were two more errors I encountered: 1) boost-python2 is outdated and didn't match the system's boost version (1.76.0 vs 1.78.0). After manually compiling 1.78.0 of boost-python2 it worked.

2) package() failed as linuxcnc.sh couldn't be found. The corresponding line in the PKGBUILD should read:

install -Dm 644 "${srcdir}/${pkgname}-${pkgver}/src/linuxcnc.sh" -t "${pkgdir}/etc/profile.d/"

Thanks for maintaining the package!
