目录下有加减乘除4个头文件和源文件如下

jackiexiao@debian:/opt/jackiexiao/makefile/src/math$ ls
add.cpp add.h devide.cpp devide.h Makefile minus.cpp minus.h multi.cpp multi.h

jackiexiao@debian:/opt/jackiexiao/makefile/src/math$ cat Makefile

## FILE: Makefile

## TARGET: generate libztxmath.a
## $^ : 所有依赖
## $@ : 目标文件
## $< : 第一个依赖
## g++ -g -o main main.cpp

GXX := g++
INCLUDE_FILE := ./%.h
SRC_FILES := $(wildcard *.cpp)
OBJ_FILES=$(SRC_FILES:%.cpp=./.objs/%.o)
TARGET := ../lib/libztxmath.a
CFLAGS=-I./ -Wall -Werror -fPIC -ggdb
AR := ar
ARFLAG := -rc

$(TARGET) : $(SRC_FILES) $(OBJ_FILES)
$(AR) $(ARFLAG) $(TARGET) $(OBJ_FILES)

$(DEP_FILES): ./%.d : ./%.cpp
@echo "generate dependence $@"
@printf "../" > $@.tmp
@$(GXX) -MM $< $(CFLAGS) >> $@.tmp 2> /dev/null
@mv $@.tmp $@

$(OBJ_FILES) : ./.objs/%.o : ./%.cpp
$(GXX) -o $@ -c $< $(CFLAGS)

clean:
-rm $(TARGET) $(OBJ_FILES)

sinclude $(DEP_FILES)
