Vscode在linux下配置c/c++环境

（Vscode）Linux远程c/c++环境搭建

Linux端安装基础软件

1、换源

vi /etc/apt/sources.list

//阿里云源 18.04

deb http://mirrors.aliyun.com/ubuntu/ bionic-proposed main restricted universe multiverse

1、安装ssh

sudo apt-get install openssh-server

2、安装gcc，g++

sudo apt-get install gcc g++

3、安装gdb

sudo apt-get install gdb

4、安装cmake

sudo apt-get install cmake

5、安装open_vm_tools
Vmware Tools工具官方已经不建议。更提倡开源的open-vm-tools，所以我安装了这个：

sudo apt install open-vm-tools

#如果要实现文件夹共享，需要安装 open-vm-tools-dkms
sudo apt install open-vm-tools-dkms

#桌面环境还需要安装 open-vm-tools-desktop 以支持双向拖放文件
sudo apt install open-vm-tools-desktop

Vscode安装插件并配置免密登录

1、安装Remote -ssh插件

2、配置免密登录

先在window下生成公钥：

ssh-keygen -t rsa

再在linux下生成公钥

ssh-keygen -t rsa

在linux生成公钥的目录下，创建authorized_keys文件，并写入windows下生成的公钥

Vscode在Linux下导入头文件警告

这是因为在配置中没有指定依赖路径导致的，在c_cpp_properties.json文件中includePath的默认配置只有当前目录，需要将系统依赖导入进去。
编辑~/.vscode/c_cpp_properties.json
（ctrl + shift + p，键入C/Cpp : Edit Configurations，这样就打开了配置文件）， 在includePath字段添加头文件的路径即可

在linux系统中输入命令：

gcc -v -E -x c++ -

将最后面的include路径都添加到c_cpp_properties.json文件中，该文件在vscode工作目录下.vscode文件夹中
