A simple make will build the first target in the list, which is put-files. make all will build the target all. If you want all to be the default, then move it to the top of the list. To understand what the .PHONY does, see http://www.gnu.org/s/hello/manual/make/Phony-Targets.html
Use make -d or make –debug[=flags] options: ‘-d’ Print debugging information in addition to normal processing. The debugging information says which files are being considered for remaking, which file-times are being compared and with what results, which files actually need to be remade, which implicit rules are considered and which are applied—everything interesting about how … Read more
Check out the override directive. You will probably need to modify the makefile once, but it should do what you want. Example makefile: override CFLAGS += -Wall app: main.c gcc $(CFLAGS) -o app main.c Example command lines: $ make gcc -Wall -o app main.c $ make CFLAGS=-g gcc -g -Wall -o app main.c
In fact all is explained in the doc: Finds whitespace-separated words in TEXT … means that one or more spaces have to separate the words. … that match PATTERN … means that it select only words that match a pattern (which can include some spaces). … and replaces them with REPLACEMENT. means that the selected … Read more
After re-reading the documentation on static pattern rules, I derived the following pattern rule which seems to work. $(OBJ_DEBUG): $(OBJDIR_DEBUG)/%.o: %.cpp $(CXX) $(CFLAGS_DEBUG) $(INC_DEBUG) -c $< -o $@ I’m not sure this is the best approach, and I’m open to suggestions.
Does the following function meet the purpose? FILTER_OUT = $(foreach v,$(2),$(if $(findstring $(1),$(v)),,$(v))) $(call FILTER_OUT,g, seven eight nine ten)
Your tutorial promotes old and bad practices, you should avoid it IMHO. In your rule here: $(ODIR)/%.o: %.c $(DEPS) You’re telling make to look for sources in the current directory while they actually reside in the src directory, thus this pattern is never used and you have no suitable one. Make sure you organize your … Read more
Use the shell function to execute the cygpath utility with the -w flag. Example: BAR := /cygdrive/c/foo/bar WIN_BAR := $(shell cygpath -w ${BAR}) cygpath accepts a lot of additional options. See the man page for details.
My preference is for release: $(MAKE) clean $(MAKE) test1 This forces the two targets to be made consecutively without disturbing their inner parallelism (if any).
Since you’re using GNU Make, you can make the following adjustment to your Makefile: .PRECIOUS: $(BUILD)/%.pp # ADD THIS LINE $(BUILD)/%.pp: %.c $(ECHO) “PreProcess $<” $(Q)$(CC) $(CFLAGS) -E -Wp,-C,-dD,-dI -o $@ $< The documentation has this to say about .PRECIOUS directives: The targets which .PRECIOUS depends on are given the following special treatment: if make … Read more
