![]() If you create a good makefile, only the necessary rules (compiler/link commands) will run, which stands "to next" from the modified file in the dependency path. The rule may produce/update further files, which may trigger other rules and so on. If there's any, it triggers the rule, which depends on it. When you launch make, it reads Makefile, and checks for changed files. There are files (source, object, executable) in this graph, and rules ( make's terminology). # $(OBJS) should be automagically removed right after linking.Ī simple program's compilation workflow is simple, I can draw it as a small graph: source -> -> object -> executable. # OBJS are automagically compiled by make.īIN = $(patsubst = Compile the executables # =- NOTHING TO CHANGE BELOW THIS LINE =īINS := $(patsubst %,%$(PRG_SUFFIX),$(PRGS)) # Sets PRGS BINS and OBJS using pattern substitution. # Sets SRC to a list of *.c files in PWD using wildcard. # Set CFLAGS and LDFLAGS according to your needs. # Set PRG_SUFFIX_FLAG below to either 0 or 1 to enable or disable ![]() # then you may be interested in using this makefile. a common case when compiling the programs of some chapter, # This makefile should suffice for simple projects that require building c file has a main() function, and each object # The purpose of this makefile is to compile to executable all C source # 'A Generic Makefile for Building Multiple main() Targets in $PWD' ![]()
