Anyone recommend how a person could get started with autotools in building a C project?
I found this tutorial given by Thomas Petazzoni at the Embedded Linux Conference 2016 very helpful to start learning autotools: Autotools: A Demystification Tutorial
Here are the associated slides: GNU Autotools Tutorial Slides
He gives demonstrations and good examples that are in my opinion a good start before going further with the already mentioned A. Duret-Lutz tutorial.
