Arch Linux User Repository

The package contains udev rules for i2c, to use them add your user to the i2c group:

sudo gpasswd -a $USER i2c

Also you have to load the i2c-dev kernel module at boot, if you don't have it already:

sudo sh -c 'echo i2c-dev > /etc/modules-load.d/ddc.conf'

and reboot.

@tornado99: The error says you are still running kde plasma 5.25. To build this package with 5.26 you have to upgrade the system packages (especially plasma-workspace) first.

CMake Error at CMakeLists.txt:57 (find_package): Can't build:

'Could not find a configuration file for package "LibKWorkspace" that is compatible with requested version "5.26.2".The following configuration files were considered but not accepted: /usr/lib64/cmake/LibKWorkspace/LibKWorkspaceConfig.cmake, version: 5.25.5 /usr/lib/cmake/LibKWorkspace/LibKWorkspaceConfig.cmake, version: 5.25.5 /lib64/cmake/LibKWorkspace/LibKWorkspaceConfig.cmake, version: 5.25.5 /lib/cmake/LibKWorkspace/LibKWorkspaceConfig.cmake, version: 5.25.5'

@Thaodan: No, I did not, since there were already tickets. First 2020 it was declined, because upstream default is to disable it: https://bugs.archlinux.org/task/67533

Then it was enabled for a while: https://github.com/archlinux/svntogit-packages/commit/1bc296b31c67c3555815db41d22b140b3af552e7

Few months later this bug was created: https://bugs.archlinux.org/task/70525 Which caused the change to disable it again: https://github.com/archlinux/svntogit-packages/commit/274840f272926b74361a0cabf809e877d5a2adb5

Did you try to create a bug in flyspray to enable this on the official package? As this doesn't require any patches it should be easy.

definitio: Right, was added with 5.23 - I added it now here as well.

Please add power-profiles-daemon as optional dependency. The package in official repository has it.

Hi prroet, thanks for your suggestion. Though I tried it and it does not make a difference - build including packaging takes 21 seconds for me. It already builds in parallel if MAKEFLAGS are set accordingly: https://wiki.archlinux.org/title/makepkg#Improving_compile_times Would recommend to configure it there, so you can utilize all cores not just for building this package. Usually pkgbuilds only override this if >1 would cause issues.

I found a small improvement to reduce compile time:

i2c-tools contains many binaries, shared libs and a python module, which are all unnecessary for this package. I think it makes more sense to supply the 2 small config fragments here directly. i2c-tools can be installed separately if actually needed, as it doesn't cause conflicts.
