Makefile（二）

将生产的.o文件放进指定的文件中（先创建该文件夹）

src = $(wildcard ./*.cpp)
obj = $(patsubst %.cpp,./output/%.o,$(src))target = test$(target) : $(obj)g++ $(obj) -o $(target)
%.o: %.cppg++ -c $< -o output/$@.PHONY:clean
clean:rm -f $(target) $(obj)

 将生产的最终可执行文件放进指定的文件夹中（可以不先创建文件夹）

VERSION = 1.0.0SOURCE = $(wildcard ./*.cpp)
OBJ = $(patsubst %.cpp,%.o,$(SOURCE))INCLUDE = -I /usr/include/mysql/LIBS = -lmysqlclient
LIB_PATH = -L /usr/lib/mysql/CFALGS = -gTARGET = test$(TARGET): $(OBJ)@mkdir -p output/g++ $(OBJ) $(LIB_PATH) $(LIBS) -o output/$(TARGET).$(VERSION)%.o : %.cppg++ $(INCLUDE) $(CFALGS) -c $< -o $@.PHONY: clean
clean:rm -rf $(OBJ) output/
