在Windows上使用VSCode远程链接到Linux上开发并调试C++程序

Linux安装相应工具

Debian 和 Ubuntu

apt install -y gcc make gdb

CentOS

yum install -y gcc make gdb

VSCode安装Remote Development

1.jpg

安装后可以看到一个新的图标,点击后选中SSH Targets

添加链接配置

新建config文件

D:_Projects_Source_bak\2021\linux\ssh\config

3.jpg

编辑完config配置文件保存后,VSCode配置链接

4.jpg

配置完成后,在SSH TARGETS下会显示config配置的远程目标(主机)

链接

右键点击远程目标(主机),选择任意一种connect
如果出现如下错误

5.jpg

表示本地(windows)电脑没有安装SSH客户端,可以安装Git客户端解决
下载地址:https://www.git-scm.com/downloads
然后会提示输入远程Linux登录密码

6.jpg

链接成功,打开远程linux C++工程存放路径

7.jpg

会列出Linux的文件系统,让你选择工作目录,比如(新建: root\ProDir),选好后点击旁边的OK即可:
如果使用密码验证,此处有可能会让你再输入一次密码.后面很多步骤也有可能反复验证

Linux端安装C/C++扩展

注意,这些扩展需要VSCode链接到Linux后再安装,安装时会显示"安装到SSH:远程linux"

创建工程

main.c

#include

void main()
{
    int a=0;
    a++;
    a+=2;
    a-=3;
    printf("a=%d\n",a);
    return;
}

Makefile

# C compiler options
CC  = gcc
#CFLAGS = -g -O2             
RELEASE = release.elf
DEBUG   = debug.elf
LIBS = 
INC = 

# Source files

开始调试

按F5,选择工程类型:
