Cross-compilation and multi-target build systems are among the words that tend to frighten a lot of people, mostly because they evoke images of hugely complicated build scripts that require arcane incantations to perform the desired operation. In this chapter, we'll be looking at a simple Makefile-based build system, based on a build system that has seen use in commercial projects across a range of hardware targets.
The one thing that makes a build system pleasant to use is to be able to get everything set up for compilation with minimal fuss and have a central location from which we can control all relevant aspects of building the project, or parts of it, along with building and running tests.
For this reason, we have a single Makefile at the top of the project, which handles all of the basics, including the determining of which platform we run...
