Hi Jonathan and Efraim, I had time to look into these patches. I added all the neccessary packages for squeekboard and updated the system packages. However, there is still issue with the build as squeekboard fails to build on missing function implementation. [1] Efraim, could you please help with the features error? I checked other Guix rust packages but didn't get any hint. [1] https://gitlab.gnome.org/World/Phosh/squeekboard/-/issues/349 ---- Petr
