Note that these are different from the libsystemd's and libudev's pkg-config files, which can still be found in the respective dev packages, but instead provide data such as the installation directories for units, and more. many thanks Stuart On Sun, Jan 25, 2026 at 7:00 AM Stuart Stevenson <[email protected]> wrote: > > > 25Jan2026 exercise: > > ran > > cd linuxcnc-source-dev > ./debian/configure > sudo apt-get build-deb . > > attached file is the output from those commands > > then ran the following > > stustev@attlocal:~/linuxcnc-source-dir$ sudo apt update > [sudo] password for stustev: > Hit:1 http://deb.debian.org/debian trixie InRelease > Hit:2 > http://download.opensuse.org/repositories/science:/EtherLab/Debian_12 ./ > InRelease > Hit:4 https://www.linuxcnc.org trixie InRelease > > Hit:3 https://repository.qtpyvcp.com/apt develop InRelease > All packages are up to date. > stustev@attlocal:~/linuxcnc-source-dir$ sudo apt install libudev-dev > libudev-dev is already the newest version (257.9-1~deb13u1). > Summary: > Upgrading: 0, Installing: 0, Removing: 0, Not Upgrading: 0 > stustev@attlocal:~/linuxcnc-source-dev > > no joy - configure gives the same result - udev not found > > As an afterthought I ran > > sudo apt upgrade > > To see if that included anything more.
