How to write a small makefile?

**Squall** · 18th March 2012, 23:27

Hello, I want to write a makefile that compiles each .cpp files with the same command and create an executable file with all .o files.

Qt Code:

Switch view

$(OUTPUT): ?dependencies?
	$(LINK) $^ -o $@ $(LIBS) $(LFLAGS)
 
$(OBJECTS_DIR)/%.o: $(SOURCES_DIR)/%.cpp $(SOURCES_DIR)/%.hpp
	$(CXX) $< -c -o $@ $(INCLUDE) $(CXXFLAGS)

$(OUTPUT): ?dependencies?
	$(LINK) $^ -o $@ $(LIBS) $(LFLAGS)

$(OBJECTS_DIR)/%.o: $(SOURCES_DIR)/%.cpp $(SOURCES_DIR)/%.hpp
	$(CXX) $< -c -o $@ $(INCLUDE) $(CXXFLAGS)

To copy to clipboard, switch view to plain text mode

The problem is the dependencies of the main rule. I tried $(OBJECTS_DIR)/%.o but it does not work. I do not want to write the name of each .o file.
The dependencies names are all .cpp files that are in $(SOURCES_DIR) folder, with .o suffix instead of .cpp and in $(OBJECTS_DIR) folder.

Thanks
