Install basic software on Linux

Install ssh

yum install openssh-server #安装

service sshd status #查看状态

Install g++

＃　安装g++　要用root权限运行
yum install gcc-c++

g++ -v #查看版本

Install gdb

yum install gdb #安装

gdb -v  #查看版本

Install cmake

yum install cmake #安装

cmake --version #查看版本

make --version #查看版本

VsCode install service plugin

• Remote  -Containers
• Remote  -SSH
• Remote  -SSH:Editing Configuration Files
• Remote  -WSL
• Remote  -Containers

Establish remote connection configuration

 

• Select the platform (here, select linux), enter the password to connect to the storage server to connect .

Remote need to install the plug-in again

Create project example

• Create folder, get path

• Open folder

• Create Cmake project (Ctrl + Shift + p)

• Create case file

• hello.txt

This is a test!

• main.cpp

#include <iostream>
#include <sys/types.h>
#include <sys/stat.h>
#include <fcntl.h>
#include <unistd.h>

int main(int ,char**){
    int fd = open("../hello.txt", O_RDWR);
    if (-1 == fd){
        std::cerr << "erro \n" ;
        return -1;
    }
for(;;){
    char buffer[1024] = {};
    ssize_t len = read(fd, buffer, sizeof(buffer));
    if(0 == len){
        break;
    }  
    buffer[len] = '\0';
    std::cout << buffer << std::endl;
}
    close(fd);
    return 0；
}

• Compilation output

Remote debugging example

• Set via configuration file

• Use absolute path when debugging, otherwise an error will be reported (after modification, compile first and then debug)

• To debug
