The thing people miss a lot about makefile, apart from what has already been mentioned is the fact you can have "local" version of the "global" variables, per rules. It's very very powerfull, clear to read, and simplify all these if/else/end no end... For example: CFLAGS = -std=gnu99 -Werror release/%.elf: CFLAGS += -DRELEASE debug/%.elf: CFLAGS += -DDEBUG Basically you can add your own context flags and variables for each individual targets, and they are 'inherited' by any of their /sub/ targets... Oh, people also need to learn about VPATH or course [0]! [0]: https://www.gnu.org/software/make/manual/html_node/General-Search.html https://www.gnu.org/software/make/manual/html_node/General-S...
