rcpy for beaglebone blue

[ryansel...@gmail.com]

Hello,

I'm just getting into beaglebone and working with linux in general. I have the robotics controller library loaded and up to date. I would like to use rcpy. The first step on the rcpy documentation is to install libgpiod. I can git that fine, but when I go to do the autogen step, it gives me an error saying "libgpiod needs linux headers version >= v5.5.0". The kernel I have is 4.19 from the most recent flashed image. Is there anyway around this?

Thanks in advance

Try installing libgpiod from the debian package repository - with luck you might find an older version which supports the available kernel version. 

Run "apt search libgpiod" and see if the packages are there; then install them as usual ("sudo apt install libgpiod libgpiod-dev" or something similar). For compiling other source code against it, you'll also need the development package which ends with "-dev".

Kind regards,

Tarmo

Strange, I don't recall explicitly installing those packages; they may
be part of the standard Beagle images.

Correct libgpiod is installed by default.. There are a few projects
that utilize that library in the standard image..
