How to Print in Makefile

Source: https://stackoverflow.com/questions/11775733/how-can-i-print-message-in-makefile/11776179

 15 # for TRACEGEN
 16 include $(MAKEDIR)/Tools.make
 17
 18 ifeq ($(CONFIG_SOMETHING),y)
 19 EXTRA_CFLAGS += -fsanitize=kernel-address
 20 $(info ************  TEST VERSION ************)
 21 else
 22 $(info ************  ELSE VERSION ************)
 23 endif

$(info your_text) : Information. This doesn't stop the execution.

$(warning your_text) : Warning. This shows the text as a warning.

$(error your_text) : Fatal Error. This will stop the execution.

To print a variable in Makefile:

 18 $(info $$CONFIG_VAR1 is [${CONFIG_VAR1}])

 19 $(info $$CONFIG_VAR2 is [${CONFIG_VAR2}])

What is the smallest integer greater than 95555 in which there will be 4 identical numbers?

Ans: 96666? nope, its 95999 :-)
