VS code配置编译及debug环境

一. 在.vscode下建两个文件

     1.1. tasks.json:配置编译

     1.2. lunch.json配置debug 

           PS:附录中我提供源文件

 

二.   创建makefile,以便json调用

三.  build

        3.1. 打开源码文件

        3.2. 编译

                 点击菜单上Terminal->config Task->make build

       3.2. clean

                 点击菜单上Terminal->config Task->clean

 

 四. Debug

    4.1. 按F5开始debug(或按菜单上的Run)

    4.2. 设置断点(在行前左击)

 

     4.3. 如果运行时不执行断点,报信息如下

         4.3.1. Module containing this breakpoint has not yet loaded or the breakpoint address not be obtained

                如果你编译没有加-g时,调试就会出现这个信息

 五. 附录

    5.1. tasks.json

            ],
            "options": {
                "cwd": "${workspaceFolder}"
            },
            "problemMatcher": [

            ],
            "group": "build"
        }
    ]

CC = /usr/bin/gcc

# 正则表达式表示目录下所有.c文件,相当于:SRCS = main.c a.c b.c

# .PHONE伪目标,具体含义百度一下一大堆介绍
.PHONY:all debug clean

# 要生成的目标文件
all: $(TARGET)
# 第一行依赖关系:冒号后面为依赖的文件,相当于Hello: main.o a.o b.o
# 第二行规则:$@表示目标文件,$^表示所有依赖文件,$<表示第一个依赖文件
$(TARGET): $(OBJS)

# 上一句目标文件依赖一大堆.o文件,这句表示所有.o都由相应名字的.c文件自动生成

    # make clean删除所有.o和目标文件
clean:
