1.make简介：
https://blog.youkuaiyun.com/abc13526222160/article/details/94853883
make是一个命令工具，是一个解释makefile中指令的命令工具

2.Makefile中符号的含义：

3.报错： target pattern contains no ‘%‘
删除*.d 和*.o文件 ok
find -name '*.d' -type f -print -exec rm -rf {} \;
find -name '*.o' -type f -print -exec rm -rf {} \;

4.linux环境打包img用到exe程序
ubuntu安装:apt-get install wine-development
sudo apt-get update

5.windows和虚拟机内linux无法共享文件，且vmware工具是灰色:

6.编译helloworld：
编译了那些目录下的文件？
路径：at1k-sdk-v2
   ./device/at1k/src/
   ./device/core/
   ./rtos/portable/
   ./project/example/
   /middleware/newlib/
   ./middleware/log/
   ./middleware/util/
   不是所有源码的所有文件的都编译
   同个路径下有的文件编译有的文件不编译

怎么设置编译哪些文件？
   makefile的依赖关系：
   最顶层的依赖是？
            make -j 执行的是：all:: dir $(LINK_DEPS) $(OBJS) $(BIN) force #$(BIN_DUMP)
   代表什么含义？
       all:: 等价于all:
       find -name 和find -iname 搜索的结果一样


       AT1K_SDK_HOME_SH =at1k-sdk-v2
       BUILDSCRIPT_DIR = ./tools/mk
       LINKER_SCRIPT        =    $(AT1K_SDK_HOME_SH)/$(BUILDSCRIPT_DIR)/link.lds
       LINK_DEPS            +=    $(LINKER_SCRIPT)
       LINK_DEPS = at1k-sdk-v2/./tools/mk/link.lds

       //查找./device/所有.S文件
       DEVICE_DIR            =    ./device/
       BOOT_ASM_SRC       =    $(shell cd $(AT1K_SDK_HOME); find $(DEVICE_DIR) -iname "*.S" | sed -e 's/.\///1')

       //把./device/所有.S文件替换为 .O文件保存到 helloworld路径下相关文件夹
       BUILDTOPDIR           =   ./BUILD
       CHIP                ?=   AT1K
       BUILDDIR            =    ./$(BUILDTOPDIR)/$(CHIP)/GCC_RISCV
       BUILDDIR = ././BUILD/AT1K/GCC_RISCV
       BOOT_ASM_OBJ       =    $(patsubst %.S, $(BUILDDIR)/%.o, $(BOOT_ASM_SRC)) //单纯实现替换

       //把./rtos/portable/所有.S文件替换为 .O文件保存到 helloworld路径下相关文件夹
       AT1K_SDK_HOME = at1k-sdk-v2
       PORT_DIR            =    ./rtos/portable
       RTOS_PORT_ASM_SRC   =    $(shell cd $(AT1K_SDK_HOME); find $(PORT_DIR) -iname "*.S" | sed -e 's/.\///1')
       RTOS_PORT_ASM_OBJ =    $(patsubst %.S, $(BUILDDIR)/%.o, $(RTOS_PORT_ASM_SRC))

       ASM_OBJS     =    $(BOOT_ASM_OBJ) $(RTOS_PORT_ASM_OBJ) $(MID_ASM_OBJ)

       APP_OBJ               =    $(patsubst %.c, $(BUILDDIR)/%.o, $(APP_SRC))

       //APP_OBJ：把main.c 拷贝为main.o
       //$(APP_CC_OBJ) $(MID_OBJ)
       //RTOS_OBJ：list.c queue.c tasks.c timers.c event_groups.c stream_buffer.c
       RTOS_PORT_OBJ：port.c

       DRIVER_DIR            =    ./device/peripheral
       DRIVER_OBJ:./device/peripheral下所有.c文件
       DEVICE_OBJ：./device/at1k/下所有.c文件
       CC_SRC：

       C_OBJS     =    $(APP_OBJ) $(APP_CC_OBJ) $(MID_OBJ) $(RTOS_OBJ) $(RTOS_PORT_OBJ) $(DRIVER_OBJ) $(DEVICE_OBJ) $(CC_OBJ)
       OBJS = $(ASM_OBJS) $(C_OBJS)

       TARGET = helloworld
       BIN    =    $(TARGET)
       $(BIN): $(OBJS) //目标依赖的点O文件不存在，会自动生成点o，文件 hello:main.o
           @$(CC) -MMD -MP -o $@ $(LDFLAGS) $(OBJS) $(EXTERNAL_OBJ) $(SYSLIBS) $(LIBS) $(LIBSFLAGS) $(STRIP)
           等价于
           LDFLAGS = T/at1k-sdk-v2/./tools/mk/link.lds -static -Wl,--gc-sections -Wl,--check-sections --stats -Wl,--print-memory-usage -Wl,-Map=all.map -Wl,--noinhibit-exec -march=rv32imfcxpulpv2 -mabi=ilp32f
           OBJS = 所有.o文件
           EXTERNAL_OBJ =空
           SYSLIBS = 空
           LIBS = -nostartfiles -lm -lc -lgcc -nostdlib -nodefaultlibs
           LIBSFLAGS = 空
           STRIP = 空
