install error related to gpiod #78
Description
Hello,
Trying to install daqhats on rpi5 with current (as of 08 October 2025) Raspberry pi OS.
Followed instructions in order and get an error trying to make via the script. Relevant section of errors excerpted.
Seems to be an issue related to the version of libgpiod-dev available versus expected by daqhats.
Ideas appreciated.
