NRF5 SDK uses dirty hack to dump list of object to link:
define dump $(eval CONTENT_TO_DUMP := $(1)) \ "$(MAKE)" -s --no-print-directory \ -f "$(TEMPLATE_PATH)/dump.mk" VARIABLE=CONTENT_TO_DUMP endef export CONTENT_TO_DUMP
which is called by
GENERATE_LD_INPUT_FILE = $(call dump, $^ $(LIB_FILES)) > $(@:.out=.in) LD_INPUT = @$(@:.out=.in)
to generate e.g. `mouse-n.in` file with list of files to link:
../../build_mouse-n_debug_nrf52840dk/mouse-n/nrf_log_frontend.c.o ../../build_mouse-n_debug_nrf52840dk/mouse-n/nrf_log_str_formatter.c.o </code> When make is used with parallelism enabled stdout is not synchronised by default. So some output from previous make target is catched by above macro which cause linker to show error. Additional lines looks like: <file txt mouse-n.in> make[1]: Entering directory ../../build_mouse-n_debug_nrf52840dk/mouse-n/nrf_log_frontend.c.o ../../build_mouse-n_debug_nrf52840dk/mouse-n/nrf_log_str_formatter.c.o
Solution 1:
NRF provides switch PASS_LINKER_INPUT_VIA_FILE to disable generation
of intermediate file and let pass list of object to link as arguments.
As side effects - long list of file with paths are printed.
Solution 2:
Patch NRF SDK and add -O argument to $(MAKE) to enforce output synchronisation.
