I've built linuxcnc from source many times, but since upgrading to trixie, it no longer works. I'm following the instructions at
Building LinuxCNC
. I don't think they are entirely correct. In section 4.2 (Building Debian Packages) it says the following:The result of ./debian/configure is bash: ./debian/configure: No such file or directory
If I don't cd into src, like it says in the previous step, then configure works.
The result of sudo apt-get build-dep . is Error: Unsupported file . given on commandline
The result without the . is Error: Unable to locate package build-dep
If I just go ahead anyway and run the last line, it seems to compile but ends with:
Since it appears buildbot is not building debs for trixie, my only option is to build from source. What is the correct procedure for building deb files for trixie? Thanks,
Jim

linuxcnc.org/dists/trixie/2.9-uspace/bin...pace_2.9.8_amd64.deb
Download and double click to install with gdebi, and in case gdebi is missing:
sudo apt update
sudo apt install gdebi

Thanks tommylight but I'm trying to build from master branch. Probably should have mentioned that.

I have done a video on this. There is a bookmark for cloning and compiling.
Master branch build process has been updated but I think there is a typo in the docs. Now getting dependencies is done the debian way with a single command line. This is an amazing improvement

I should mention I show how to build for RIP but you can keep with the Debian way and build the debs and install with sudo dpkg -i on the folder above where you are.

Thanks Rod, I managed to build a deb in a bookworm chroot but it won't install on trixie because linuxcnc requires python3.11 and trixie uses python3.13. I also tried installing the deb from buildbot2 but same result. Looks like I have no option but to reinstall bookworm. Major PITA.
On that note, I recall you posted the 6.3.0-rt11-linuxcnc kernel somewhere, but I can no longer find it. Could you tell me where that is? Thanks again.

Following this with interest (I had the exact same problem) - my goal was rebuilding the mot2-eth driver. Will review all the advice here when I've had more coffee but PITA if we can't build from a Trixie installation.
