Hello,
I'm looking for good tutorials/books on Gnu Tool Chain and Gnu Build System.
To be more specific, I am looking for information that starts with just the source code & gradually adds build files & uses Gnu Tool Chain step by step.
In other words looking for an example which shows how to construct/build a project from the scratch to a full fledged project.
From the Gnu Build System you linked above:
Learning the GNU development tools
They go through a "Hello World" type of example. The whole of section 5 seems pretty nice.
