## Makefile多文件编译 ##

编译库

TARGET=libmytest.so
    
    all: $(TARGET)
    
    CFLAGS += -Os -Wall \
    		-I. \
    		-I./common \
    		-I../include
    
    LDFLAGS += -L. -L.. -L../../lib
    
    C_FILES=./common/common.c \
    		./common/common_os.c
    
    C_FILES+=./src/shared/queue.c \
    		./src/shared/util.c \
    		./src/shared/mgmt.c \
    		./src/shared/crypto.c \
    		./src/shared/mainloop.c
    
    C_FILES+=./arch.c \
    		./arch_os.c\
    		./arch_os_timer.c\
    		./app.c
    
    
    OBJS = $(patsubst %c, %o, $(C_FILES))
    LDLIBS = -lrt -lpthread
    
    
    $(OBJS): %.o : %.c
    	$(CC) -c $(CFLAGS) $< -o $@
    
    $(TARGET): $(OBJS)
    	$(CC) $(CFLAGS) $^ $(LDLIBS) -fPIC -shared -o $(TARGET)
    
    clean:
    	rm -rf $(OBJS) $(TARGET)

CC = aarch64-linux-gnu-c++
    CFLAGS = #-O2
    DBUG = -g
    INCLUDE = -I../out/include/ -I../out/include/alize-core/include/ -I../dao/ -I../
    LIBS = -lpthread -lsqlite3
    LD_FLAG = -L../out/lib
    SRCS = $(wildcard *.cpp)  
    OBJS = $(patsubst %cpp, %o, $(SRCS))
    CGIS = $(patsubst %cpp, %cgi, $(SRCS))
    DEP_OBJS = ../dao/sysUserDml.o ../logApi/log.o ../utils/util.o
    
    .PHONY : clean
    all: $(CGIS)
    
    .c.o:
    	$(CC) $(DBUG) -c $(CFLAGS)  $(INCLUDE) $<  
    .cpp.o:
    	$(CC) $(DBUG) -c $(CFLAGS)  $(INCLUDE) $<  
    %.cgi : %.o
    	$(CC) $(DBUG) -o $@ $(OBJS) $(DEP_OBJS) $(LD_FLAG) $(LIBS) $(INCLUDE)
    
    clean :
    	-rm -f $(OBJS) $(CGIS)

## 改进方法 ##

CC = aarch64-linux-gnu-c++
    CFLAGS = #-O2
    DBUG = -g
    INCLUDE = -I../out/include/ -I../out/include/alize-core/include/ -I../dao/ -I../model -I../utils -I.
    LIBS = -lpthread -lsqlite3 -lcgic
    LD_FLAG = -L../out/lib
    SRCS = $(wildcard *.cpp)  
    OBJS = $(patsubst %cpp, %o, $(SRCS))
    CGIS = $(patsubst %cpp, %cgi, $(SRCS))
    DEP_OBJS = ../dao/sysUserDml.o \
    			../dao/userEnrollDml.o \
    			../logApi/log.o \
    			../utils/util.o \
    			../model/userEnroll.o
    
    .PHONY : clean
    all:$(CGIS)
    	
    clean :
    	-rm -f $(OBJS) $(CGIS)
    
    $(CGIS) : %.cgi : %.o 
    	$(CC) $(DBUG)  $(DEP_OBJS) $(LD_FLAG) $(LIBS) $(INCLUDE) $< -o $@
    
    $(OBJS): %.o : %.cpp 
    	$(CC) -c $(DBUG)  $(CFLAGS)  $(INCLUDE)  $<

## 类似使用方式 ##

BIN = test
    SRCS = $(wildcard *.cpp)  
    OBJS = $(patsubst %cpp, %o, $(SRCS))
    
    .PHONY : clean
    all:$(BIN)
    	
    clean :
    	-rm -f $(OBJS) $(BIN)
    
    $(BIN) : $(OBJS)
    	$(CXX) -o $@ $ *.o $(LD_FLAG) $(LIBS)
    
    $(OBJS): %.o : %.cpp 
    	$(CXX) -c $(CFLAGS)  $<

# Makefile编译子目录 #

dirs:= multi_code_table/src \
    multi_main/src \
    multi_msg_find/src \
    multi_set_up/src \
    multi_user_table/src \
    sms_code_set/src \
    top/src \
    user_table_set/src
    all:
    	$(foreach N, $(dirs),make -C $(N);)
    clean:
    	$(foreach N, $(dirs),make clean -C $(N);)

# 常用命令 #

*  打印当前目录

$(warning $(shell pwd))

*  文件模式进行替换

#$(patsubst 原模式， 目标模式， 文件列表)
    OBJS = $(patsubst %.c, %.o, $(SRC))

*  foreach循环

$(foreach var , list, text)
    names := test main log caffe
    files := $(foreach n , $(name), $(n).o )
    输出files的值为：“test.o main.o log.o caffe.o
