**实现一个简单的两个c文件的编译**

# makefile文件 方法一
    CC = gcc  #编译器的型号
     
    .PHONY: all #伪所址 不管有没有all  都会执行
    all: hello.c tool.o  #
    	$(CC) hello.c tool.o -o all # 生成 all.o文件
    tool.o:tool.c
    	$(CC) -c tool.c
    clean:           #清除文件
    	rm *.o all

CC = gcc  #编译器的型号
    RM      = rm -rf #删除命令
    
    ## 目标文件  方法二
    TARGET     := all
    
    ## source file path
    SRC_PATH   := .
    
    ## get all source files
    SRCS         = $(wildcard $(SRC_PATH)/*.c ) ## all .o based on all .c OBJS := $(SRCS:.c=.o) ## used headers file path INCLUDE_PATH := . ## get all include path CFLAGS += $(foreach dir, $(INCLUDE_PATH), -I$(dir)) .PHONY: all #伪所址 不管有没有all 都会执行 $(TARGET): @echo $(SRCS) $(CC) -c $(CFLAGS) $(SRCS) $(CC) $(CFLAGS) -o $(TARGET) $(OBJS) # $(LDFLAGS) $(RM) $(OBJS) clean: #清除文件 $(RM) *.o $(TARGET)

//hello.c 文件

    }
