Accepting Constraints in Build Systems

As Embedded Systems become more complex, the complexity of the process to build the software for these systems also increases. As humans, our ability to deal with complexity is limited, so we develop tools and processes to manage the complexity. In the end, these tools and processes are about constraints and patterns. A well-designed tool or process encourages you to do things in a way that is consistent and maintainable, which leads to reliable and predictable results.

As we work with larger and more complex systems (i.e. Linux), more and more of our time is spent on integration and pulling different pieces together. We often need to debug or understand code we did not write — especially in build systems. To work effectively in this scenario you must be able to quickly search through a lot of source code. Therefore, we are always looking for ways to make this more efficient.

I’ve already written about using autotools and qmake in OE. With recent projects, we’re using CMake to build most C/C++ components. Like any good tool, CMake has a learning curve, but it seems to do its job quite well. Below are examples of a CMake build file, and corresponding OE recipe.
