I include __TIME__ and __DATE__ strings in some files (main.c & commands.c) - I want these files to be recompiled everytime even if they
are not changed. I am using teh standard makefile structure. How can I do this?

Hello,
I'm no makefile expert, but according to the stackoverflow thread linked below it seems like the most common approach is to create a new target named FORCE that is always run and then add this target as a dependency to the object files you want to rebuild every time.

You may try to add the lines below to the end of your project Makefile.
$(OUTPUT_DIRECTORY)/${TARGETS}/main.c.o: FORCE $(OUTPUT_DIRECTORY)/${TARGETS}/commands.c.o: FORCE .PHONY: FORCE FORCE:

Hi Vidar - thanks, that works! And ChatGPT helped me modify this as follows:
# Add files here that need to be recompiled every time, e.g. because they contain __TIME__ and __DATE__ FILES_TO_FORCE_REBUILD := main ble_commands # Force recompilation of any files in the last that contain __TIME__ and __DATE__ # Generate rules for each file in FILES_TO_FORCE_REBUILD list: $(foreach file, $(FILES_TO_FORCE_REBUILD), \ $(eval $(OUTPUT_DIRECTORY)/${TARGETS}/$(file).c.o: FORCE) \ ) .PHONY: FORCE FORCE:
