本地vscode，搭建centos7的c语言开发环境

• 远程主机一台或本地虚拟主机一台；本地电脑需要安装vscode的软件，vscode下载链接；vscode需要安装remote-ssh插件
  *vscode的debug参考文档

• 远程主机

  • 安装gcc yum install -y gcc gdb
  • 查看gcc是否安装成功，gcc -v

• vscode用远程开发工具链接到centos

  • 打开插件市场，搜索c/c++
  • 重启vscode

#创建一个文件夹
mkdir demo
touch main.c

# include <stdio.h>

int main(void) {
    printf("hello, world\n");
    return 0;
}

• vscode选择顶部菜单栏依次选择 Terminal > Configure Default Build Task，并在弹出框里选择 C/C++: gcc build active file。

{
	"version": "2.0.0",
	"tasks": [
		{
			"type": "cppbuild",
			"label": "C/C++: gcc 生成活动文件",
			"command": "/usr/bin/gcc",
			"args": [
				"-fdiagnostics-color=always",
				"-g",
				"${file}",
				"-o",
				"${fileDirname}/build/${fileBasenameNoExtension}"
			],
			"options": {
				"cwd": "${workspaceFolder}"
			},
			"problemMatcher": [
				"$gcc"
			],
			"group": {
				"kind": "build",
				"isDefault": true
			},
			"detail": "编译器: /usr/bin/gcc"
		},
	]
}

• vscode创建一个launch.json,选择Add Debug Configuration，选择g++ build and debug active file.
