Hands-On Embedded Programming with C++17

Platform-independent build systems

Ideally, the project and build system we choose could be used to build the target platform on any desktop platform. Usually, the main consideration here is the availability of the same toolchain and programmer for each development platform. Fortunately, for AVR- and ARM-based MCU platforms, the same GCC-based toolchain is available, so that we do not have to take different toolchains with different naming conventions, flags and settings into account.

The remaining challenge is simply to invoke the toolchain, and subsequently the programmer utility, in a way that doesn't require any knowledge of the underlying OS.

In Chapter 6, Testing OS-Based Applications, we looked at a multitarget build system, which ...
