Hello make experts. I decided to write this letter again since I forgot about topic. I'm trying to use Auto-Dependency Generation form this article - Auto-Dependency GenerationThe article is very nice but i'm stuck. dependencies are generated in .d folder correctly as written in the article but make doesn't build if i change a header file. Here is my Makefile:
# -*- Makefile -*- DEP_DIR := .d $(shell mkdir -p $(DEP_DIR) >/dev/null) DEPFLAGS = -MT $@ -MMD -MP -MF $(DEP_DIR)/$*.Td POSTCOMPILE = @mv -f $(DEP_DIR)/$*.Td $(DEP_DIR)/$*.d && touch $@ CXX := g++ CXXFLAGS := -std=c++17 -g LIBS := -lsome_lib PRODUCT := main SRC_DIR := src SRCFILES := $(wildcard $(SRC_DIR)/*.cpp) OBJFILES := $(patsubst %.cpp,%.o,$(SRCFILES)) all: $(PRODUCT) $(SRC_DIR)/%.o: $(SRC_DIR)/%.cpp $(DEP_DIR)/%.d $(CXX) $(DEPFLAGS) $(CXXFLAGS) -o $@ -c $^ $(POSTCOMPILE) $(PRODUCT): $(OBJFILES) $(CXX) $^ $(LIBS) -o $@ $(DEP_DIR)/%.d: ; .PRECIOUS: $(DEP_DIR)/%.d .PHONY: clean clean: find ./src -name '*.o' -delete find . -name '*.o' -delete rm $(PRODUCT) include $(wildcard $(patsubst %,$(DEP_DIR)/%.d,$(basename $(SRCFILES)))) Source files(cpp and hpp) are located in src folder. I'm using gnu make 4.2.1 for mingw. Have a wonderful time. _______________________________________________ Help-make mailing list Help-make@gnu.org https://lists.gnu.org/mailman/listinfo/help-make
